Installing new templates in Visual Studio 2005
If you have installed new templates in Visual Studio 2005 you might have experienced the fact that they don’t show up in the Add New Item list. This can happen because VS2005 uses a template cache that isn’t always updated correctly. However there is a quick and simple fix for this that was unfortunately not documented very well. This quick fix is to run DevEnv.exe with the /InstallVSTemplates option from the command line. Doing this will force VS2005 to rebuild its template cache and you should be good to go.
