Hi
I am using Visual Studio 2019 Blend programming in Visual Basic.
I programmed a simple form and at once I start not being able to see the Form designer and I received the error "System.windows.forms.form couldnt be loaded"
I tried to find if there was a solution for this but I could not find it.
thanks for any help

Hi @federico La Volpe ,
According to your description, I have two questions to confirm with you.
Does this problem occur every time you program a form?
Could you provide a little sample or some screenshots to help us reproduce your problem?
We are waiting for your update.

If the designer cannot load the form then it tells you what is wrong in the yellow bar at the top. If you click that area it will jump to the problem code. The issue is almost always related to a change that prevents the form code from compiling. Please post the error information.
