Add authorization using groups & group claims to an ASP.NET Core Web app that signs-in users with the Microsoft identity platform

Build status

Overview

This sample demonstrates a ASP.NET Core Web App calling Microsoft Graph.

ℹ️ To learn how applications integrate with Microsoft Graph, consider going through the recorded session:: An introduction to Microsoft Graph for developers In doing so, it implements Role-based Access Control (RBAC) by using Microsoft Entra ID Security Groups

Role based access control in Microsoft Entra ID can be done with Delegated and App permissions and App Roles as well. We will cover RBAC using App Roles in the next tutorial. Delegated and App permissions, Security Groups and App Roles in Microsoft Entra ID are by no means mutually exclusive - they can be used in tandem to provide even finer grained access control.

ℹ️ To learn more on using security groups and app roles in your app AD,consider going through the recorded session: Implement authorization in your applications with App roles and Security Groups with the Microsoft identity platform

Scenario

This sample demonstrates a ASP.NET Core Web App calling Microsoft Graph.

  1. The client ASP.NET Core Web App uses the Microsoft.Identity.Web to sign-in a user and obtain a JWT ID Token and an Access Token from Microsoft Entra ID.
  2. The access token is used as a bearer token to authorize the user to call the Microsoft Graph protected by Microsoft Entra ID.

Scenario Image

Prerequisites

This sample will not work with a personal Microsoft account. If you're signed in to the Microsoft Entra admin center with a personal Microsoft account and have not created a user account in your directory before, you will need to create one before proceeding.

Setup the sample

Step 1: Clone or download this repository

From your shell or command line:

git clone https://github.com/Azure-Samples/microsoft-identity-platform-aspnetcore-webapp-tutorial.git

or download and extract the repository .zip file.

⚠️ To avoid path length limitations on Windows, we recommend cloning into a directory near the root of your drive.

Step 2: Navigate to project folder

cd 5-WebApp-AuthZ\5-2-Groups

Step 3: Register the sample application(s) in your tenant

There is one project in this sample. To register it, you can:

  • follow the steps below for manually register your apps

  • or use PowerShell scripts that:

    • automatically creates the Microsoft Entra applications and related objects (passwords, permissions, dependencies) for you.
    • modify the projects' configuration files.
    Expand this section if you want to use this automation:

    ⚠️ If you have never used Microsoft Graph PowerShell before, we recommend you go through the App Creation Scripts Guide once to ensure that your environment is prepared correctly for this step.

    1. On Windows, run PowerShell as Administrator and navigate to the root of the cloned directory

    2. In PowerShell run:

      Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process -Force

    3. Run the script to create your Microsoft Entra application and configure the code of the sample application accordingly.

    4. For interactive process -in PowerShell, run:

      cd .\AppCreationScripts\
.\Configure.ps1 -TenantId "[Optional] - your tenant id" -AzureEnvironmentName "[Optional] - Azure environment, defaults to 'Global'"

    Other ways of running the scripts are described in App Creation Scripts guide. The scripts also provide a guide to automated application registration, configuration and removal which can help in your CI/CD scenarios.

Choose the Microsoft Entra tenant where you want to create your applications

To manually register the apps, as a first step you'll need to:

  1. Sign in to the Microsoft Entra admin center.
  2. If your account is present in more than one Microsoft Entra tenant, select your profile at the top right corner in the menu on top of the page, and then switch directory to change your portal session to the desired Microsoft Entra tenant.

Register the webApp app (WebApp-GroupClaims)

  1. Navigate to the Microsoft Entra admin center and select the Microsoft Entra ID service.
  2. Select the App Registrations blade on the left, then select New registration.
  3. In the Register an application page that appears, enter your application's registration information:
    1. In the Name section, enter a meaningful application name that will be displayed to users of the app, for example WebApp-GroupClaims.
    2. Under Supported account types, select Accounts in this organizational directory only
    3. Select Register to create the application.
  4. In the Overview blade, find and note the Application (client) ID. You use this value in your app's configuration file(s) later in your code.
  5. In the app's registration screen, select the Authentication blade to the left.
  6. If you don't have a platform added, select Add a platform and select the Web option.
    1. In the Redirect URI section enter the following redirect URIs:
      1. https://localhost:44321/
      2. https://localhost:44321/signin-oidc
    2. In the Front-channel logout URL section, set it to https://localhost:44321/signout-oidc.
    3. In the Implicit grant section, check the ID tokens option as this sample requires the Implicit grant flow to be enabled to sign-in the user and call an API.
    4. Select ID tokens (used for implicit and hybrid flows) checkbox.
    5. Click Save to save your changes.
  7. In the app's registration screen, select the Certificates & secrets blade in the left to open the page where you can generate secrets and upload certificates.
  8. In the Client secrets section, select New client secret:
    1. Type a key description (for instance app secret).
    2. Select one of the available key durations (6 months, 12 months or Custom) as per your security posture.
    3. The generated key value will be displayed when you select the Add button. Copy and save the generated value for use in later steps.
    4. You'll need this key later in your code's configuration files. This key value will not be displayed again, and is not retrievable by any other means, so make sure to note it from the Microsoft Entra admin center before navigating to any other screen or blade.

    💡 For enhanced security, instead of using client secrets, consider using certificates and Azure KeyVault.

    1. Since this app signs-in users, we will now proceed to select delegated permissions, which is is required by apps signing-in users.
    2. In the app's registration screen, select the API permissions blade in the left to open the page where we add access to the APIs that your application needs:
    3. Select the Add a permission button and then:
    4. Ensure that the Microsoft APIs tab is selected.
    5. In the Commonly used Microsoft APIs section, select Microsoft Graph
    • Since this app signs-in users, we will now proceed to select delegated permissions, which is requested by apps that signs-in users.
    • In the Delegated permissions section, select User.Read, GroupMember.Read.All in the list. Use the search box if necessary.
    1. Select the Add permissions button at the bottom.

    ⚠️ To handle the groups overage scenario, please grant admin consent to the Microsoft Graph GroupMember.Read.All permission. See the section on how to create the overage scenario for testing below for more.

Configure Optional Claims
  1. Still on the same app registration, select the Token configuration blade to the left.
  2. Select Add optional claim:
    1. Select optional claim type, then choose ID.
    2. Select the optional claim acct.

    Provides user's account status in tenant. If the user is a member of the tenant, the value is 0. If they're a guest, the value is 1.

    1. Select Add to save your changes.

Create Security Groups

⚠️ You may already have security groups with the names defined below in your tenant and/or you may not have permissions to create new security groups. In that case, skip the steps below and update the configuration files in your project(s) with the desired names/IDs of existing groups in your tenant.

  1. Navigate to the Microsoft Entra admin center and select the Microsoft Entra ID service.
  2. Select Groups blade on the left.
  3. In the Groups blade, select New Group.
    1. For Group Type, select Security
    2. For Group Name, enter GroupAdmin
    3. For Group Description, enter Admin Security Group
    4. Add Group Owners and Group Members as you see fit.
    5. Select Create.
  4. In the Groups blade, select New Group.
    1. For Group Type, select Security
    2. For Group Name, enter GroupMember
    3. For Group Description, enter User Security Group
    4. Add Group Owners and Group Members as you see fit.
    5. Select Create.
  5. Assign the user accounts that you plan to work with to these security groups.

For more information, visit: Create a basic group and add members using Microsoft Entra ID

Configure Security Groups

You have two different options available to you on how you can further configure your application to receive the groups claim.

  1. Receive all the groups that the signed-in user is assigned to in a Microsoft Entra tenant, included nested groups.
  2. Receive the groups claim values from a filtered set of groups that your application is programmed to work with (Not available in the Microsoft Entra ID Free edition).

To get the on-premise group's samAccountName or On Premises Group Security Identifier instead of Group ID, please refer to the document Configure group claims for applications with Microsoft Entra ID.

Configure your application to receive all the groups the signed-in user is assigned to, including nested groups

  1. In the app's registration screen, select the Token Configuration blade in the left to open the page where you can configure the claims provided tokens issued to your application.
  2. Select the Add groups claim button on top to open the Edit Groups Claim screen.
  3. Select Security groups or the All groups (includes distribution lists but not groups assigned to the application) option. Choosing both negates the effect of Security Groups option.
  4. Under the ID section, select Group ID. This will result in Microsoft Entra ID sending the object id of the groups the user is assigned to in the groups claim of the ID Token that your app receives after signing-in a user.

Configure your application to receive the groups claim values from a filtered set of groups a user may be assigned to

Prerequisites, benefits and limitations of using this option
  1. This option is useful when your application is interested in a selected set of groups that a signing-in user may be assigned to and not every security group this user is assigned to in the tenant. This option also saves your application from running into the overage issue.
  2. This feature is not available in the Microsoft Entra ID Free edition.
  3. Nested group assignments are not available when this option is utilized.
Steps to enable this option in your app
  1. In the app's registration screen, select the Token Configuration blade in the left to open the page where you can configure the claims provided tokens issued to your application.
  2. Select the Add groups claim button on top to open the Edit Groups Claim screen.
  3. Select Groups assigned to the application.
    1. Choosing additional options like Security Groups or All groups (includes distribution lists but not groups assigned to the application) will negate the benefits your app derives from choosing to use this option.
  4. Under the ID section, select Group ID. This will result in Microsoft Entra ID sending the object id of the groups the user is assigned to in the groups claim of the ID Token that your app receives after signing-in a user.
  5. If you wish to have 'groups' claims available to Access Tokens issued to your Web API, then you can also choose the Group ID option under the Access section. This will result in Microsoft Entra ID sending the Object ID of the groups the user is assigned to in the groups claim of the Access Token issued to the client applications of your API.
  6. In the app's registration screen, select on the Overview blade in the left to open the Application overview screen. Select the hyperlink with the name of your application in Managed application in local directory (note this field title can be truncated for instance Managed application in ...). When you select this link you will navigate to the Enterprise Application Overview page associated with the service principal for your application in the tenant where you created it. You can navigate back to the app registration page by using the back button of your browser.
  7. Select the Users and groups blade in the left to open the page where you can assign users and groups to your application.
    1. Select the Add user button on the top row.
    2. Select User and Groups from the resultant screen.
    3. Choose the groups that you want to assign to this application.
    4. Click Select in the bottom to finish selecting the groups.
    5. Select Assign to finish the group assignment process.
    6. Your application will now receive these selected groups in the groups claim when a user signing in to your app is a member of one or more these assigned groups.
  8. Select the Properties blade in the left to open the page that lists the basic properties of your application.Set the User assignment required? flag to Yes.

💡 Important security tip

When you set User assignment required? to Yes, Microsoft Entra ID will check that only users assigned to your application in the Users and groups blade are able to sign-in to your app.To enable this, follow the instructions here. You can assign users directly or by assigning security groups they belong to.

Configure the webApp app (WebApp-GroupClaims) to use your app registration

Open the project in your IDE (like Visual Studio or Visual Studio Code) to configure the code.

In the steps below, "ClientID" is the same as "Application ID" or "AppId".

  1. Open the appsettings.json file.
  2. Find the key ClientId and replace the existing value with the application ID (clientId) of WebApp-GroupClaims app copied from the Microsoft Entra admin center.
  3. Find the key TenantId and replace the existing value with your Microsoft Entra tenant/directory ID.
  4. Find the key ClientSecret and replace the existing value with the generated secret that you saved during the creation of WebApp-GroupClaims copied from the Microsoft Entra admin center.
  5. Find the key Enter the objectID for GroupAdmin group copied from Microsoft Entra admin center and replace the existing value with the GroupAdmin object id from Azure.
  6. Find the key Enter the objectID for GroupMember group copied from Microsoft Entra admin center and replace the existing value with the GroupMember object id from Azure.

Configure the app to recognize Group IDs

⚠️ During Token Configuration, if you have chosen any other option except groupID (e.g. like DNSDomain\sAMAccountName) you should enter the group name (for example contoso.com\Test Group) instead of the object ID below:

  1. Open the "\..\appsettings.json" file.
    1. Find the keys for the security Group and replace the existing value with the object ID of the group copied from the Microsoft Entra admin center.

Step 4: Running the sample

Run the sample using Visual Studio

For Visual Studio Users

Clean the solution, rebuild the solution, and run it.

Run the sample using a command line interface such as VS Code integrated terminal

Step 1. Install .NET Core dependencies
   dotnet restore
Step 2. Trust development certificates
   dotnet dev-certs https --clean
   dotnet dev-certs https --trust

Learn more about HTTPS in .NET Core.

Step 3. Run the applications

In the console window execute the below command:

    dotnet run

Explore the sample

  1. Open your web browser and make a request to the app. The app immediately attempts to authenticate you to the Microsoft identity platform. You can sign-in with a work or school account from the tenant where you created this app. If admin consent to GroupMember.Read.All permission from portal is not done then sign-in with admin for the first time and consent for the permission.
  2. If the Overage scenario occurs for the signed-in user then all the groups are retrieved from Microsoft Graph and added in a list. The overage scenario is discussed later in this article.
  3. On the home page, the app lists the various claims it obtained from your ID token. You'd notice one more claims named groups.
  4. On the top menu, click on the signed-in user's name [email protected], you should now see all kind of information about yourself including their picture.
  5. the Admin link leads to an empty page that can only be accessed if the signed-in user is a part of the GroupAdmin security group.

About the code

Much of the specifics of implementing RBAC with Security Groups is the same with implementing RBAC with App Roles discussed in the previous tutorial. In order to avoid redundancy, here we discuss particular issues, such as groups overage, that might arise with using the groups claim.

.NET Core app configuration and how to handle the overage scenario

  1. In Startup.cs, OnTokenValidated event calls ProcessAnyGroupsOverage method defined in GraphHelper.cs to process groups overage claim.
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddMicrosoftIdentityWebApp(options =>
        {
            // code omitted for brevity...
            options.Events.OnTokenValidated = async context =>
            {
                // code omitted for brevity...
                if (context != null)
                {
                    // Calls method to process groups overage claim (before policy checks kick-in)
                    await GraphHelper.ProcessAnyGroupsOverage(context, requiredGroupsIds);
                }
                await Task.CompletedTask;
            };
        })
    .EnableTokenAcquisitionToCallDownstreamApi(options => Configuration.Bind("AzureAd", options))
    .AddMicrosoftGraph(Configuration.GetSection("GraphAPI"))
    .AddInMemoryTokenCaches();

AddMicrosoftGraph registers the service for GraphServiceClient. The values for BaseUrl and Scopes defined in GraphAPI section of the appsettings.json.

  1. In GraphHelper.cs, ProcessAnyGroupsOverage method checks if incoming token contains the Group Overage claim. If so, it will call ProcessUserGroupsForOverage method to retrieve groups, which in turn calls the Microsoft Graph /checkMemberGroups endpoint.
public static async Task ProcessAnyGroupsOverage(TokenValidatedContext context)
{
    // Checks if the incoming token contains a groups overage claim.
    if (HasOverageOccurred(context.Principal))
    {
        await ProcessUserGroupsForOverage(context, requiredGroupsIds);
    }
}

  1. UserProfileController.cs

    1. Checks authorization of signed-in user for [Authorize(Policy = AuthorizationPolicies.AssignmentToGroupMemberGroupRequired)]. If authorized successfully then obtain information from the /me and /me/photo endpoints by using GraphServiceClient.

  2. UserProfile\Index.cshtml

    1. Has some client code that prints the signed-in user's information. Much of the specifics of implementing RBAC with Security Groups is the same with implementing RBAC with App Roles discussed in the previous tutorial. In order to avoid redundancy, here we discuss particular issues, such as groups overage, that might arise with using the groups claim.

  3. AdminController.cs

    1. Checks authorization of signed-in user for [Authorize(Policy = AuthorizationPolicies.AssignmentToGroupAdminGroupRequired)]. If authorized successfully a simple place holder page is displayed.

  4. Admin\Index.cshtml

    1. A simple place holder to show how you can store hidden content only available to members of the GroupAdmin group

Caching user group memberships in overage scenario

Since overaged tokens will not contain group membership IDs, yet these IDs are required for controlling access to pages and/or resources, applications have to call Microsoft Graph whenever a user action (e.g. accessing a page on the UI, accessing a todolist item in the web API etc.) takes place. These network calls are costly and will impact the application performance and user experience. As such the project benefits from caching the group membership IDs once they are fetched from Microsoft Graph for the first time. By default, these are cached for 1 hour in the sample. Cached groups will miss any changes to a users group membership for this duration. If you need more fine grained control, you can configure cache duration in appsettings.json. If your scenario requires capturing real-time changes to a user's group membership, consider implementing Microsoft Graph change notifications instead.

Group authorization policy

The ASP.NET middleware supports roles populated from claims by specifying the claim in the RoleClaimType property of TokenValidationParameters. Since the groups claim contains the object IDs of the security groups than the actual names by default, you'd use the group IDs instead of group names. See Role-based authorization in ASP.NET Core for more info. See Startup.cs for more.

// The following lines code instruct the asp.net core middleware to use the data in the "groups" claim in the [Authorize] attribute and for User.IsInrole()
// See https://docs.microsoft.com/aspnet/core/security/authorization/roles
services.Configure<OpenIdConnectOptions>(OpenIdConnectDefaults.AuthenticationScheme, options =>
{
    // Use the groups claim for populating roles
    options.TokenValidationParameters.RoleClaimType = "groups";
});
// Adding authorization policies that enforce authorization using Microsoft Entra roles.
services.AddAuthorization(options =>
{
    options.AddPolicy(AuthorizationPolicies.AssignmentToGroupMemberGroupRequired, policy => policy.RequireRole(Configuration["Groups:GroupMember"], Configuration["Groups:GroupAdmin"]));
    options.AddPolicy(AuthorizationPolicies.AssignmentToGroupAdminGroupRequired, policy => policy.RequireRole(Configuration["Groups:GroupAdmin"]));
});

These policies can be used in controllers as shown below:

[Authorize(Policy = AuthorizationPolicies.AssignmentToGroupMemberGroupRequired)]
[AuthorizeForScopes(Scopes = new[] { Constants.ScopeUserRead })]        
public async Task<IActionResult> Index()
{
    try
    {
        User me = await _graphServiceClient.Me.GetAsync();
        ViewData["Me"] = me;

        var photo = await _graphServiceClient.Me.Photo.GetAsync();
        ViewData["Photo"] = photo;
    }
    // See 'Optional - Handle Continuous Access Evaluation (CAE) challenge from Microsoft Graph' for more information.
    catch (ServiceException svcex) when (svcex.Message.Contains("Continuous access evaluation resulted in claims challenge"))
    {
        // Left blank for brevity.
    }
    catch (ServiceException svcex) when (svcex.Error.Code == "ImageNotFound")
    {
        //swallow
    }

    return View();
}

The Groups Overage Claim

To ensure that the token size doesn’t exceed HTTP header size limits, the Microsoft Identity Platform limits the number of object Ids that it includes in the groups claim.

If a user is member of more groups than the overage limit (150 for SAML tokens, 200 for JWT tokens, 6 for single-page applications using implicit flow), then the Microsoft Identity Platform does not emit the group IDs in the groups claim in the token. Instead, it includes an overage claim in the token that indicates to the application to query the MS Graph API to retrieve the user’s group membership.

Create the Overage Scenario for testing

  1. You can use the BulkCreateGroups.ps1 provided in the App Creation Scripts folder to create a large number of groups and assign users to them. This will help test overage scenarios during development. You'll need to enter a user's object ID when prompted by the BulkCreateGroups.ps1 script. If you would like to delete these groups after your testing, run the BulkRemoveGroups.ps1.

When attending to overage scenarios, which requires a call to Microsoft Graph to read the signed-in user's group memberships, your app will need to have the User.Read and GroupMember.Read.All for the getMemberGroups function to execute successfully.

⚠️ For the overage scenario, make sure you have granted Admin Consent for the MS Graph API's GroupMember.Read.All scope for both the Client and the Service apps (see the App Registration steps above).

Detecting group overage in your code by examining claims

  1. When you run this sample and an overage occurred, then you'd see the _claim_names in the home page after the user signs-in.

  2. We strongly advise you use the group filtering feature (if possible) to avoid running into group overages.

  3. In case you cannot avoid running into group overage, we suggest you use the following logic to process groups claim in your token.

    1. Check for the claim _claim_names with one of the values being groups. This indicates overage.
    2. If found, make a call to the endpoint specified in _claim_sources to fetch user’s groups.
    3. If none found, look into the groups claim for user’s groups.

Optional - Handle Continuous Access Evaluation (CAE) challenge from Microsoft Graph

Continuous access evaluation (CAE) enables web APIs to do just-in time token validation, for instance enforcing user session revocation in the case of password change/reset but there are other benefits. For details, see Continuous access evaluation.

Microsoft Graph is now CAE-enabled in Preview. This means that it can ask its clients for more claims when conditional access policies require it. Your can enable your application to be ready to consume CAE-enabled APIs by:

  1. Declaring that the client app is capable of handling claims challenges from the web API.
  2. Processing these challenges when thrown.

Declare the CAE capability in the configuration

This sample declares that it's CAE-capable by adding a ClientCapabilities property in the configuration, whose value is [ "cp1" ].

{
  "AzureAd": {
    // ...
    // the following is required to handle Continuous Access Evaluation challenges
    "ClientCapabilities": [ "cp1" ],
    // ...
  },
  // ...
}

Process the CAE challenge from Microsoft Graph

To process the CAE challenge from Microsoft Graph, the controller actions need to extract it from the wwwAuthenticate header. It is returned when MS Graph rejects a seemingly valid Access tokens for MS Graph. For this you need to:

  1. Inject and instance of MicrosoftIdentityConsentAndConditionalAccessHandler in the controller constructor. The beginning of the HomeController becomes:

     private readonly GraphServiceClient _graphServiceClient;
 private readonly MicrosoftIdentityConsentAndConditionalAccessHandler _consentHandler;
 private string[] _graphScopes;

 public UserProfileController(
     IConfiguration configuration, 
     GraphServiceClient graphServiceClient,
     MicrosoftIdentityConsentAndConditionalAccessHandler consentHandler)
 {

     _consentHandler = consentHandler;
     _graphServiceClient = graphServiceClient;
     _graphScopes = configuration.GetValue<string>("GraphAPI:Scopes")?.Split(' ');
 }
 
 // more code here

  2. The process to handle CAE challenges from MS Graph comprises of the following steps:

    1. Catch a Microsoft Graph SDK's ServiceException and extract the required claims. This is done by wrapping the call to Microsoft Graph into a try/catch block that processes the challenge:
    User me = await _graphServiceClient.Me.GetAsync();
    1. Then redirect the user back to Microsoft Entra ID with the new requested claims. Microsoft Entra ID will use this claims payload to discern what or if any additional processing is required, example being the user needs to sign-in again or do multi-factor authentication.
  try
  {
      User me = await _graphServiceClient.Me.GetAsync();
      ViewData["Me"] = me;

      var photo = await _graphServiceClient.Me.Photo.GetAsync();
      ViewData["Photo"] = photo;
  }
  // Catch CAE exception from Graph SDK
  catch (ServiceException svcex) when (svcex.Message.Contains("Continuous access evaluation resulted in claims challenge"))
  {
      try
      {
          string claimChallenge = WwwAuthenticateParameters.GetClaimChallengeFromResponseHeaders(svcex.ResponseHeaders);
          _consentHandler.ChallengeUser(_graphScopes, claimChallenge);
          return new EmptyResult();
      }
      catch (Exception ex2)
      {
          _consentHandler.HandleException(ex2);
      }
  }
  catch (ServiceException svcex) when (svcex.Error.Code == "ImageNotFound")
  {
      //swallow
  }

Deploying Web app to Azure App Service

There is one web app in this sample. To deploy it to Azure App Services, you'll need to:

  • create an Azure App Service
  • publish the projects to the App Services, and
  • update its client(s) to call the website instead of the local environment.

Publish your files (WebApp-GroupClaims)

Publish using Visual Studio

Follow the link to Publish with Visual Studio.

Publish using Visual Studio Code
  1. Install the Visual Studio Code extension Azure App Service.
  2. Follow the link to Publish with Visual Studio Code

Update the Microsoft Entra app registration (WebApp-GroupClaims)

  1. Navigate back to to the Microsoft Entra admin center. In the left-hand navigation pane, select the Microsoft Entra ID service, and then select App registrations (Preview).
  2. In the resulting screen, select the WebApp-GroupClaims application.
  3. In the app's registration screen, select Authentication in the menu.
    1. In the Redirect URIs section, update the reply URLs to match the site URL of your Azure deployment. For example:
      1. https://WebApp-GroupClaims.azurewebsites.net/
      2. https://WebApp-GroupClaims.azurewebsites.net/signin-oidc
    2. Update the Front-channel logout URL fields with the address of your service, for example https://WebApp-GroupClaims.azurewebsites.net

⚠️ If your app is using an in-memory storage, Azure App Services will spin down your web site if it is inactive, and any records that your app was keeping will be empty. In addition, if you increase the instance count of your website, requests will be distributed among the instances. Your app's records, therefore, will not be the same on each instance.
