I'm unable to debug a WinForms C# application using the released version of Visual Studio 2010 Prof.

I get the following error message after the second debugging run.

Error 9 Unable to copy file "obj\x86\Debug\Arrowgrass Reports.exe" to "bin\Debug\Arrowgrass Reports.exe". The process cannot access the file 'bin\Debug\Arrowgrass Reports.exe' because it is being used by another process.

I've tried a pre-build script to attempt to delete this file, but it's locked by Visual Studio.

There are a few references to this on the net so it is a know problem. Does anyone have a hotfix or effective work-around?
