C++ transform T4 template ignore output file
Not sure why you don't want the files, but...
In linux we have a wonderful thing called /dev/null
that is essentially an empty void just for things like this. I did a quick search, and Windows has it's own equivilent: NUL
Thus, the command you want is:
"C:\Program Files (x86)\Common Files\microsoft shared\TextTemplating\14.0\
TextTransform.exe" -out NUL C:\Test.tt
