I'm having a problem debugging some issues that I suspect are thread related in Silverlight. My application is failing silently, so I have no way to be sure yet. Is it possible that exceptions in a background thread are quietly swallowed? I'm pretty sure my callback is being called, but all that is in it right now is a raise statement.
I've enabled debug. <param name="initParams" value="debug=true,reportErrors=errorLocation" /> I've been trying to explore Threads a little more with IronPython to see what might be the problem, but even there I'm not having much luck. I could swear this used to work in Beta 1. Now it crashes the interpreter. IronPython 2.0 Beta (2.0.0.2000) on .NET 2.0.50727.1433 Copyright (c) Microsoft Corporation.
