Seeing slowdowns in large VB 2005 projects? Well, I think I just found the answer. There’s now a QFE released that may help address these issues. One of the applications I maintain is a 25,000 line solution made up of 9 projects, I’m hoping this fix will resolve the issues we’ve seen compiling it (not to mention the frequent compiler crashes).

Here’s the list of symptoms addressed:

• You experience a slow response time when you use single-step debugging. For example, the response time is slow when you press F10 to step into a line of code.
• You experience a slow response time when the Error List or the Task List is updated by Visual Studio 2005.
• You experience a slow response time when you use the IntelliSense feature.

Once I hear back from Microsoft support, I’ll post details if it makes any difference.
