I have two projects in my solution. The startup project is successfully able to obfuscate however, the other referenced project is not able to obfuscate successfully.

If I obfuscate individual projects separately in the same solution they are able to obfuscate but, then building the whole solution together gives build error for function(s) from other assemblies.

The highlighted path is another project reference that is part of the same solution.

Please suggest how I can resolve this error and make all the custom assemblies/projects obfuscate successfully?
