stepping through web service hangs in VS

[Jim Stallings]

I have a web service that has started exhibiting new/strange behavior when
debugging. I start the web service from Visual Studio but when execution
halts at the breakpoint, trying to single step from that point results in a
hang. When I close the browser window that was opened to display the web
service result, the aspnet_wp.exe pegs the CPU at 98% and I have to kill
aspnet_wp.exe. This behavior occurs regardless of where the breakpoint is
set. When I run the web service without a breakpoint, it runs to normal
completion. The behavior has just started and I am unable to find anything I
changed that could do this.

Running the same code base on my laptop does not have this issue. The only
difference I'm sure of on the desktop between when it worked and when it
failed was a windows update.

Which windows update was it?
