Version conflict detected for Microsoft.IdentityModel.Clients.ActiveDirectory

Question

Creating an Azure function that uses nuget packages Microsoft.Rest.ClientRuntime.Azure.Authentication for authenticating to DataLake as well as Microsoft.IdentityModel.Clients.ActiveDirectory for authenticating to HDInsight. Getting the following error when I try to install both in the function project:

uninstall-package : Version conflict detected for Microsoft.IdentityModel.Clients.ActiveDirectory. Reference the package directly from the project to resolve this issue. MyProject.Functions (>= 1.0.0) -> Microsoft.Rest.ClientRuntime.Azure.Authentication (>= 2.3.1) -> Microsoft.IdentityModel.Clients.ActiveDirectory (>= 2.28.3) MyProject.Functions (>= 1.0.0) -> Microsoft.Azure.Common.Authentication (>= 1.7.0-preview) -> Microsoft.IdentityModel.Clients.ActiveDirectory (>=2.18.206251556).

It looks like Microsoft.Azure.Common.Authentication 1.7.0-preview has a constraint on referencing Microsoft.IdentityModel.Clients.ActiveDirectory 2.18.206251556 only. Unfortunately this library has not been updated since February 2016 and I'm not sure of another way of authenticating non-interactively with HDInsight besides the steps outlined at https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-create-non-interactive-authentication-dotnet-applications

Per my understanding, you could directly use the package Microsoft.IdentityModel.Clients.ActiveDirectory to retrieve the access token instead of using the Microsoft.Azure.Common.Authentication package.

Based on your description, I created my azure function project to test this issue. I installed the packages as follows:

Method for retrieving the token:

private static string GetAuthorizationToken()
{
    string tenantId = "xxx";
    string clientId = "xxx";
    string clientSecrets = "xxx";

    var context = new AuthenticationContext(String.Format("https://login.windows.net/{0}", tenantId));
    AuthenticationResult result = context.AcquireTokenAsync(
                "https://management.azure.com/"
            , new ClientCredential(clientId, clientSecrets)
            ).Result;
    return result.AccessToken;
}

My function:

[FunctionName("Function1")]
public static void Run([TimerTrigger("*/10 * * * * *")]TimerInfo myTimer,TraceWriter log)
{
    TokenCloudCredentials tokenCredential = new TokenCloudCredentials("{subscriptionId}", GetAuthorizationToken());
    HDInsightManagementClient _hdiManagementClient = new HDInsightManagementClient(tokenCredential);
    var results = _hdiManagementClient.Clusters.List();
    foreach (var name in results.Clusters)
    {
        Console.WriteLine("Cluster Name: " + name.Name);
        Console.WriteLine("\t Cluster type: " + name.Properties.ClusterDefinition.ClusterType);
        Console.WriteLine("\t Cluster location: " + name.Location);
        Console.WriteLine("\t Cluster version: " + name.Properties.ClusterVersion);
    }
}
