Says signature for SaveChangesAsync is
public virtual System.Threading.Tasks.Task<int> SaveChangesAsync (System.Threading.CancellationToken cancellationToken = null);
If you try overriding SaveChangesAsync using the above example, it'll give you the following error:
Using default(CancellationToken) instead of null solves the issue:
public override async Task<int> SaveChangesAsync(CancellationToken cancellationToken = default(CancellationToken))
