I have built an ASF project using CDC USB, for educational purposes.
I want to add some code. I'd like to write it with C++. I added a couple of .cpp files to the project but Studio won't try to compile them.
The file's properties Build Action is set to None. I can set the Build Action to Compile, but that does no good. It still won't compile them. When I close and reopen the project the Build Action is again set to None.
I am using Studio 6.1.2440.
