It used to be that when I launched the Toolbox in Visual Studio, it would show all the UI controls available (based on whether the project is of type WinForms or WPF).
In Visual Studio 2019, the Toolbox displays empty, and then I have to do a right-click and select 'Choose Items...' and go through the tedious task of selecting the controls from the 'Choose Toolbox items' dialogue.
Every. Single. Project. Every. Single. Time.
How can I get the original behavior so that it displays pre-populated?
Try to load the default environment and services by running the Visual Studio IDE in safe mode.
devenv.exe /SafeMode
If it works, load the default settings of the Visual Studio IDE:
devenv.exe /ResetSettings
devenv.exe is located in the following directory: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE.
If devenv.exe isn't included in the system path, it can be run as follows:
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\devenv.exe" /SafeMode
