Azure Active Directory Graph Client 2.0 - Context is not currently tracking the entity

Question

I have recently installed the Azure Active Directory Graph Client Library 2.0.2 Nuget package and am unable to add Members to Groups both adding a group to a group or adding

Answer 1

I tried this new syntax but still does not work.

 public async Task> addUserToAzureGroup(Group AzGroup, User AzUser)
 {
     // link the found user with the found group
     try
     {
         AzGroup.Members.Add(AzUser as DirectoryObject);
         await AzGroup.UpdateAsync();
     }
     catch (Exception ex)
     {
         Exception myEx = new Exception(ex.Message);
         retResult.Exception = myEx;
         return retResult;
     }
     return retResult;
 }

I have almost the same error text in the execption message: The context is already tracking the relationship

Any news on that issue? Could anyone guess why that happens?

I also tried from the manage.windowsAzure.com UI and still cannot add the user! I get this error: Could not add members to group 'myAzAD_group'.
