Perfect. Not only did the await timeout as directed, but the resulting exception text identified the exact cause of the login failure.

Thanks!]]> Fri, 16 Aug 2013 11:27:42 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=4275&PID=16736#16736 Authenticator.Instance.LoginAsync : The LoginAsync call should have... http://www.ideablade.com/forum/forum_posts.asp?TID=4275&PID=16735#16735 Author: kimj

The LoginAsync call should have thrown, although the automatic retry logic may have kicked in making it look like a hang.  We can look further at that.
 
You can pass a CancellationToken with the call.  This will cancel if the login call doesn't complete within 10 seconds:
 
ILoginCredential credential = null;
var cts = new CancellationTokenSource();
cts.CancelAfter(TimeSpan.FromSeconds(10));
var ctxAuth = await Authenticator.Instance.LoginAsync(credential: credential, options: null, cancellationToken: cts.Token);

My DevForce-enabled Silverlight app was hanging on this call:

ILoginCredential credential = null;
var ctxAuth = await Authenticator.Instance.LoginAsync(credential);

Turns out I had an invalid database name in a connection string in my web.config. Thankfully, DevForce added the entry below to the log file file or I would have had no idea why it was hanging.

I want to timeout the call to the LoginAsync method (e.g., stop AWAITing) after a specified time period elapses. What is the best way to do this?

Thanks in advance.
