Fixing a broken toolbox (In Visual Studio 2010 SP1)

I was recently running into a situation where every time I opened Visual Studio 2010 SP1, the following message would appear for about 60 seconds or so:

"Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage '{2C98B35-07DA-45F1-96A3-BE55D91C8D7A}'"

Then I ended up with duplicate items in my toolbox, there is a simple solution to this problem.

After googling the problem I found a solution and I like to share it with you.

• Back up your system registry
• Then locate the following system registry entry '[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}]', after you locate this entry delete it.
• Then locate the following files locate in the following folder: 'C:\Users\Your Name Here\AppData\Local\Microsoft\VisualStudio\10.0\'
• Create a Backup Folder, then back up the files in to that folder and then delete them from there original location.
• Then start Visual Studio 2010 SP1 and this should fix this issue.

After doing some research this happens with silverlight 5 and WCF is installed.
The only problem with this solution I have found is that if you have items added to your toolbox, you will have to read the items to your toolbox, the other problem I have found with this solution is then auto processes then add items to the toolbox some times dose not work.
