@paulomorgado I know your changes don't affect compilation, but we have a policy that code files must have a corresponding project file. Are you able to add project files for the two VB files?

[paulomorgado]

@gewarren, how would I do that? This seems to be VERY old.

[JoanGil]

I had the same problem. Here I had the conversation with a solution. A simple Project file like in this example is good enough.
