If you're new to multithreading, I strongly encourage you to look at the Task Parallel Library (TPL). It simplifies threading, and gives you tools to help guarantee callback (continuation) threads occur on the UI thread.

The TPL is in the System.Threading.Tasks namespace.

Update: just seen your comment about .Net v2. TPL was introduced in .NET v3.5 or possibly as late as v4.
