CustomControlLibrary sample does not work with Visual Studio 2022

[boydpatterson]

The CustomControlLibrary sample does not work in Visual Studio 2022. When opened in Visual Studio 2019, the designer functionality is present as expected. When opening the same solution in Visual Studio 2022, there is no evidence any of the DesignTools extensibility is loaded.

The following are examples (but not all) of CustomButton designer features present in VS 2019 that were not observed in VS 2022:

• No context menu integration for "Set Background" or "Add Reference"
• Custom Date/Time picker not available to edit the "CustomButton.Date"
• Opacity slider not displayed
• Background property does not display colors list

My company is a commercial UI Controls developer, and we are not able to get our design-time functionality working in VS 2022. This is a blocking issue for our latest release.

Please update the sample to be compatible with Visual Studio 2022 so it can serve as a guide for those building designer support in the latest IDE.
