If I have commas in the file path or file name I get the following error during build:

C:\Users\Wesley.Manning.nuget\packages\wixtoolset.sdk\4.0.0-rc.4\tools\wix.targets(907,22): error MSB4186: Invalid static method invocation syntax: "[MSBuild]::MakeRelative($(FullIntermediateOutputPat
h), C:\Users\me\Github\project\msiWDriver_Win8,8.1,10_x64\obj\Release\STMicro DFU 64bit Drivers - Windows 8_8.1_10.msi)". Method '[MSBuild]::MakeRelative' not found. Static method invoc
ation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(a, b)). Check that all parameters are defined, are of the correct type, and are specified in the right order

If I remove the comma from msiWDriver_Win8,8.1,10_x64, the build error goes away.

• Describe the behavior you expected and how it differed from the actual behavior.

No build errors with commas in names of directories or files.
