Hi Fahad,

Based on the latest information, it looks like you removed the .NET Framework 4.8 Target.

The net48 target framework is currently essential for the designer to work.

If that is not the case, then we would require a small and runnable test case as mentioned in our community guidelines here: https://wisej.com/support/question/forum-guidelines

Best regards,
Alaa

Hello Fahad,

You’ll need to clean the solution, build it and then restart Visual Studio.

Best regards,
Alaa
