How to configure and build VSCode with Omnipascal and Delphi - omnipascal

Question

I have two problems.
The first is related with dfm form design preview.
Not work. I will try to simulate error message for more info. Before that I need to setup configuration due to the buld error:"Missig Form Unit".
Let start this amazing post with many different configuration. All the stuff are referring for Delphi and Omnipascal.
