Adding Azure AD Authentication to the project failed: System.Runtime.InteropServices.COMException

While configuring azure AD from visual studio, I'm getting this error:

Adding Azure AD Authentication to the project failed: System.Runtime.InteropServices.COMException

I found that it's due to writeback option not enabled on Azure AD, but I verified against Azure AD - it's properly set. This issue is coming only when I'm using app id uri to configure but when I'm using client id it's working fine.

In my case the issue was the server settings on the project. The project was linked to a local site on IIS. Removing the link and changing the setting to IIS Express fixed the issue

You should use client id , client id represents your application and is unique identifier for the application.App ID URI are used when requesting permissions to a resource application, or acquiring an access token for a resource application.

Please refer to AAD Graph Application object schema for more details on these https://msdn.microsoft.com/Library/Azure/Ad/Graph/api/entity-and-complex-type-reference#application-entity . Check the appId and identifierUris properties.
