Problems with SaveAsync task in DynamoDB for C#

Question

I'm trying to save my administrator class object to DynamoDB using Context.SaveAsync method:

// Save admin to DynamoDB.
context.SaveAsync(admin,(result)=>{
  if (result.Exception == null)
  { 
    Console.WriteLine("admin saved");
  }
});

but it keeps bothering me with following error:

cannot convert `lambda expression' to non-delegate type `system.threading.cancellationtoken'

How do I handle this issue ?. I'm using Xamarin Studio for OS X

According to the documentation, DynamoDBContext.SaveAsync takes a type T, and a CancellationToken. It does not take any form of delegate type, at all.

What you want is to do is:

public async Task SaveAsync<T>(T entity, CancellationToken ct)
{
     await context.SaveAsync<T>(entity, ct);
     Console.WriteLine("entity saved");
}
