This might be old news but it was a treat for me. In debugging some multithreaded code recently got to use the improved debugger support for threads in Visual Studio 2008 (I'm running Beta 2) that John Robbins blogged about last month and Soma blogged last week.
Take a look at the IDE screenshot below (click to Zoom).
There's a few cool and subtle things going on here. Take a look at the current instruction location in yellow. It's right at the end of the CheckDependancyCallback method - but see the gray highlight with the squiggly "thread" in the margin? That's the current location of another thread of execution.
You can name your threads now just by entering their name in the Threads toolbox window, and some threads without names will get an automatic name. You can also flag threads you're interested in watching so you don't have to remember the Thread ID.Take a look at the Debug toolbar as well. You can see the Debug Location including Process and Thread (what thread I'm currently debugging).
What a treat.
