 Adding Web Service Reference Fails in Visual Studio
                                             I'm got an error message like "The web services enumeration components are not available. You need to re-install Visual Studio to add web references to your application". while try to add web references Sounds like the installation is somehow corrupted.

And I find the following solution from net. Just click start button, click run and type the following command.

1) Run-> "devenv /resetskippkgs" , (without quotes)

2) when having 2 VS installed (like VS2008 and VS2005) on same machine it is better to parse command with the full path name:
"C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe" /resetskippkg

I'm  resolved my problem by this way...
