Visual Studio crash when adding items to the toolbox

When I tried to adding items to toolbox thru Visual studio 2008 IDE, then my visual studio has closed automatically. 

I tried many times, but I faced the same issue. I searched in Google and I got many solutions, but nothing is helped me and many people replied that it helps others, I placed the solution here. It may help you
Solution1:
Reinstall add ins by Visual Studio commands
1. devenv /setup
2. devenv /resetuserdata
3. devenv /resetsettings CSharp


Solution 2:
devenv /safemode


Then use Choose Items on toolbox and run through each of the tabs. Once you accept any exceptions raised on loading controls, you can then open Visual
Studio normally and add items.


Solution 3:
If your system contains PowerCommands installed, then

Through Microsoft's help they came up with a work around which is a simple modification to the devenv.exe.config file.


This will exist in (64 bit systems) C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE 
Or (32 bit systems) C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE


Add this XML token to the dependentAseembly list. They had me add it after the office one, but im not sure if that matters.

<dependentAssembly>
<assemblyIdentity name="office" publicKeyToken="71e9bce111e9429c" culture="neutral"/>
<codeBase version="12.0.0.0" href="PrivateAssemblies\Office12\Office.dll"/>
</dependentAssembly>
<!-NEW STUFF-->
<dependentAssembly>
<assemblyIdentity name="Microsoft.PowerCommands" publicKeyToken="null" culture="neutral"/>
<codeBase version="1.1.0.0" href="C:\Program Files (x86)\PowerCommands\Microsoft.PowerCommands.dll"/>
</dependentAssembly>

Now you should be able to run PowerCommands with VS 2008 SP1 and XAML with no crashes. I guess there will be a fix when the next PowerCommands version comes out or on .net 4.0.


Solution 4:
1. Go to your %userprofile% Folder, (Start -> Run -> Type %userprofile% -> Enter)
2. Open Application Data\Microsoft\
3. Then Clear all the content from the following folder


VisualStudio
MSDN
VSA


Then open VS IDE,  try to add the items in the toolbox.
Solution 4 is helped me. Hope it helps you!
