Update Microsoft.Azure.Management.WebSites or constrain dependency version

[ohadschn]

letsencrypt.azure.core lists Microsoft.Azure.Management.WebSites as a dependency with the condition: >= 2.0.1

However upgrading Microsoft.Azure.Management.WebSites to version 3.0.0 results in:

Error during Request or install certificate System.MissingMethodException: Method not found: 'Void Microsoft.Azure.Management.WebSites.Models.Certificate..ctor(System.String, System.String, System.String, System.String, System.String, System.String, System.Collections.Generic.IDictionary`2<System.String,System.String>, System.String, System.String, System.Collections.Generic.IList`1<System.String>, Byte[], System.String, System.String, System.String, System.Nullable`1<System.DateTime>, System.Nullable`1<System.DateTime>, System.String, System.Nullable`1<Boolean>, Byte[], System.String, Microsoft.Azure.Management.WebSites.Models.HostingEnvironmentProfile, System.String, System.String, System.Nullable`1<Microsoft.Azure.Management.WebSites.Models.KeyVaultSecretStatus>, System.String)'.

Looking at the ctor, looks like 3.0.0 indeed broke backwards compatibility (added an additional canonicalName param to the ctor). So letsencrypt.azure.core should be either upgraded, or specified with the correct dependency, namely >= 2.0.1 && < 3.0.0
