How to supply arguments with MFNETX /DEBUGPROJ?

Problem:

Supplying an argument or parameter to MFNETX /DEBUGPROJ (e.g. MFNETX /DEBUGPROJ:projectname arg) fails with an error that it cannot find the project.

Resolution:

Since spacey project names are allowed in Net Express, the MFNETX /DEBUGPROJ command treats the characters following the project name and space as part of the project name.

To avoid this to happen, you simply need to quote the project name signifying that the following the closing quote is an argument, i.e. MFNETX /DEBUGPROJ:"projectname" arg
