Just installed Community version of Visual Studio 2019 on my machine to check things out. then opened couple of my old works and got bunch of compilation errors BC30002 because compiler extension is apparently not known any more. In the past (Express version) this was working fine. After checking internet for a while, could not find anything that would confirm if this is one of the restrictions or maybe some setting need to be changed.
i can of course rewrite things but extensions are quite nice...

any thoughts?
