convert/wrap a "classic" asynchronous method that uses a callback

Solution
If you need to wrap asynchronous callbacks into `Task`s, then you can use `TaskCompletionSource<T>`. MSDN has the full details.
However, in your case, you can just use `LoginAsync` without the `UserState` parameter:
LiveLoginResult result = await authClient.LoginAsync(new[] { "var1", "var2" });
Problem
I´m trying to convert a "classic" asynchronous method that uses a callback into a async/await method. This is the code: ``` authClient.LoginCompleted += authClient_LoginCompleted; authClient.LoginAsync(new List<string>() { "var1", "var2" }, data); static void authClient_LoginCompleted(object sender, LoginCompletedEventArgs e) { ... } ``` Where "`data`" is a `UserState`, and `authClient_LoginCompleted` is the callback. I already have the logic for a async/await methods, the problem is that the interaction in windows phone with Microsoft.Live uses callbacks. I´m considering a solution using semaphore, in order not to change the logic I have. That could be a good option?
