If Your Visual Studio 2005 Solutions Open Slowly, Check WebsiteCache | Thomas F. Abraham – On Technology

If you use Visual Studio 2005 for some old projects that have not yet been converted, and they open very slowly: read this post on If Your Visual Studio Solutions Open Slowly Check WebsiteCache by Thomas F. Abraham.

Emptying your WebsiteCache directory solves the issue: it had about 30-thousand empty directories in it.

The location depends on your Windows version:

• Windows XP, Windows Server 2003 and below:
  “%USERPROFILE%\Local Settings\Application Data\Microsoft\WebsiteCache”
• Windows Vista, Windows Server 2008 and up:
  “%USERPROFILE%\AppData\Local\Microsoft\WebsiteCache”

This bug has been fixed in Visual Studio 2008 and up.
