Precompiled user control crashes VS

I have created a precompiled user control. The basic steps are to create a Web Site project then publish to generate the DLL.

Then I created a Web Application project and added a reference to the DLL. In my page I registered the DLL and was able to access the control as <prefix:control_ascx ... />.

If I run without debugging Ctrl+F5, everything works as expected. If I run with debugging F5 Visual Studio 2008 crashes. I have the VS service pack installed: Version 9.0.30729.1 SP. Any ideas how to fix this?

Your project crashed Visual Studio. It's a bug in VS, the exception code indicates that it is making a call to the C runtime library with an invalid argument. That immediately terminates the program.

This is going to be difficult to deal with, the bug lives deep inside the VS codebase no doubt. It is likely that it has something to do with your project but it is next to impossible to diagnose exactly what might be wrong with it. You'll need some trained eyes to spot the potential mistake, if any. If you don't have anybody inside your own company to do this for you, you can call Microsoft Support to get help.

They will need your project so they can repro the crash. Best thing to do is the provide a minimum repro project, one that easily demonstrates the bug. Have it ready to upload before you call, along with your credit card. In the process of creating this repro project, you often discover the reason.
