When I used VS2012 there was always a problem loading the GUI and CODE.
Now, on VS2019 it's the same.

Before loading another solution should I close the current one ?

Pete Hepple

What I have tried:

Have tried clicking on just about everything! I can get the code up on the screen OK
but not the GUI - which file is it?

I have only seen such 'problems' when the code has an error; you need to provide more details. Also, when you open a Solution any currently open one will be automatically closed by visual Studio.

There wasn't "always a problem" with the Designer and Code. If there was, it was unique to your machine.

Double-click a form in the Solution Explorer and it'll open up the Form Designer. Hit F7 and it'll open up the code for it.

You can only have one Solution loaded at a time. If you want to load another one, you'll have to close the currently loaded Solution first.
For Winforms see this video tutorial[^]
