WindowsAuthenticationAzureServiceTokenProvider.GetTokenAsync thows when using Microsoft.IdentityModel.Clients.ActiveDirectory 4+

Original Issue: https://github.com/AzureAD/azure-activedirectory-library-for-dotnet/issues/1283

All our machines are domain joined and corpnet user/group identities are replicated to Azure AD under onmicrosoft.com directory.

We’ve been using this code:

var azureServiceTokenProvider = new AzureServiceTokenProvider();
var authenticationCallback = new KeyVaultClient.AuthenticationCallback(azureServiceTokenProvider.KeyVaultTokenCallback);
var keyVaultClient = new KeyVaultClient(authenticationCallback);
keyVaultClient.GetSecretsAsync(<url>).Dump(); //this throws

to access KeyVault no problem with these packages:

  <package id="Microsoft.Azure.KeyVault" version="3.0.0" targetFramework="net461" />
  <package id="Microsoft.Azure.KeyVault.WebKey" version="3.0.0" targetFramework="net461" />
  <package id="Microsoft.Azure.Services.AppAuthentication" version="1.0.3" targetFramework="net461" />
  <package id="Microsoft.IdentityModel.Clients.ActiveDirectory" version="3.19.8" targetFramework="net461" />

However we recently had to update to “Microsoft.IdentityModel.Clients.ActiveDirectory” version=“4.0.0-preview” and the authentication workflow we have been using stopped working (ActiveDirectory 4.1-preview also fails). se we have to reference Microsoft.IdentityModel.Clients.ActiveDirectory version 4+ in most of our solutions. However Microsoft.Azure.Services.AppAuthetnication references Microsoft.IdentityModel.Clients.ActiveDirectory 3.14.2 which still had the ActiveDirectory.Platforms.dll.

This is the failure:

Parameters: Connectionstring: [No connection string specified], Resource: https://vault.azure.net, Authority: https://login.windows.net/72f988bf-86f1-41af-91ab-2d7cd011db47. Exception Message: Tried to get token using Active Directory Integrated Authentication. Access token could not be acquired. Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory.Platform, Version=3.14.2.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Even with a binding redirect this fails because the Platforms namespace is now merged into ActiveDirectory.

The simple fix would be to update the Microsoft.IdentityModel.Clients.ActiveDirectory in Azure.Services.AppAuthentication.

@Ofekw @Zenuka Wanted to let you know that we just released the newest version 1.3.0 of AppAuth, where the ADAL dependency has been updated to 4.3.

Whats the status on this? Would like to update the ActiveDirectory package to the latest version instead of keeping it at 3.19.8.
