WebMatrix Opens Wrong Version Of Visual Studio

A number of people have complained that clicking the Visual Studio Launch button in WebMatrix opens Visual Studio 2008 instead of 2010. There is an easy fix to this.

The Launch button is wired up to look for the current version of Visual Studio in the Registry, so if you find that 2008 gets launched, its because you have either installed 2008 after 2010, or reinstalled it or did something else that will have changed the current version of VS. You just need to change it back to 2010. Since this involves making changes to the Registry, the usual sensible advice applies - back it up beforehand (if you are a wimp). I've never backed up the Registry so I can't tell you how to do that.

Type Regedit in Search Programs and Files in your Start menu, double click regedit.exe and select the HKEY_CLASSES_ROOT branch. Navigate to VisualStudio.DTE. Change CurVer to VisualStudio.DTE.10.0. Then change CLSID to {656D8328-93F5-41a7-A48C-B42858161F25}. You can copy this value from here, or by opening VisualStudio.DTE.10.0 (which should be just below where you are working) and copying it from there.

Job done. Now the right version of VS should fire up at the click of that button.

If you found that it all went horribly wrong and nothing works on your machine anymore, I hope you backed up your registry...

Excellent. In my situation, I uninstalled Visual Studio 2008, but none of the registry entries associated were removed/updated. Figures...Microsoft.
