Yes, that sort of works. I tried that first, but it complained about mismatched case, but that was just a warning I mistook for an error.
However, it turns out, that I can't even use the "await", apparently because it is Silverlight app.
The error message now says, "await requires .net 4.5 or later". I think that is what I'm using, but maybe I better double check that.

I double checked. There doesn't appear to be a place to select .net version 4.5. Only Silverlight 5.

hmm.... I see C# examples in SL 5 using await. I even added the System.Threading.Tasks namespace, but still got the compiler error.
