The Most Useful .NET Utility Classes Developers Tend To Reinvent Rather Than Reuse

Unable to open Server Explorer in Visual Studio

When server explorer doesn't open when clicking on the menu option View|Server Explorer, the first solution is to run the command /ResetSkipPkgs on the visual studio command prompt. Open a development command line window by clicking on the Start|Programs|Microsoft Visual Studio 2008|Visual Studio Tools|Visual Studio 2008 Command Prompt shortcut.
Type devenv /resetskippkgs in there. What /ResetSkipPkgs does is that it clears all options to skip loading added to VSPackages by users wishing to avoid loading problem VSPackages, and then starts Visual Studio. The presence of a SkipLoading tag disables the loading of a VSPackage; clearing the tag re-enables the loading of the VSPackage.

If this doesn't work, then reinstall the visual studio again.
