Recently, I was using a 3rd party product that had toolbox items. All was good after installation, then Visual Studio crashed and my new toolbox items disappeared. Restarting didn’t help. I came across the following solution which did solve my issue.
To understand the cause of Toolbox issues and resolve them, perform the following steps:
- Open the "%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\14.0" folder and remove all .TBD files.
- Run the Registry Editor (regedit.exe).
- Locate the following keys:
Remove these keys with their sub-keys.
Launch Visual Studio 2014 using the following command line:
In a 32-bit Windows:
"C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE\devenv" /ResetSkipPkgs /log "<my_folder>\ActivityLog.xml"
In a 64-bit Windows:
"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv" /ResetSkipPkgs /log "<my_folder>\ActivityLog.xml"
Open Visual Studio – relaunch and hopefully all is good.
