[SOLVED] Conditional compilation of pipeline Content based on Visual Studio project / platform

13

I came across this issue recently and I agree that the problem is that any “/platform:” in the .mgcb file will take priority over any argument passed from the command line. This problem is made worse because of the fact that using the pipeline tool will add the “/platform:” line to the file when you save, even if it was removed. I found a solution to this by setting up a target to run before the content build that will comment out the problematic line.

To fix it just append this to the end of your .csproj file.
