Constantly getting "Loading toolbox content from package" in Visual Studio AND IT TAKES FOREVER!

Question

Does anyone else have this problem?

The full message in the status bar says,

Loading toolbox content from package 'Microsoft.VisualStudio.IDE.ToolboxControlsInstaller.ToolboxInstallerPackage' {D766DAA8-F81E-4621-9184-F21C7F389796}

This usually happens whenever I open a xaml file and VS sits there, unresponsive, for about 2 minutes.

Answer 1

This usually happens when opening the Toolbox (CTRL-ALT-X), or moving the mouse over the Toolbox icon (which appears on the left).

According to this Connect issue report, there's a workaround to be done, which may fix the issue:

He said he simply removed the registry key under:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\    VisualStudio\10.0\Packages\{D766DAA8-F81E-4621-9184-F21C7F389796}  

and the problem went away. Read more on that link.

• Be sure to take a backup of whatever registry changes you make!
