#Source Control

I'm testing git-source-control and I have problem with a CSP application.

I was able to configure in settings a CSP application that use the path /csp/myapp, that worked.

I have another application /slg and I'm unable to add it to Git.
I created the mapping as "/CSP/" - "/slg" - "csp/slg/", then in Studio when I right click on the CSP folder in the Namespace Work Area, select Git -> Add:

We have some custom tools that do project based deployment from environment to environment. In VS Code, we're struggling to find the best way to export PRJ files that contain the contents of a project the way we were able to in Studio. We can edit existing projects, and in server side editing we can create projects, but we can't seem to extract the project files (Not the classes, the wrapper) to store in our source control solution for deployment purposes.

Looking for advice on best practise (or at least reasonable approaches) for handling the Production class when utilising source control. (And perhaps wider advice around deployment.)
