VS2017 + IVF2017(update4, w_comp_lib_2017.4.210)
I found if 'preprocess source file' is set to Yes, the compile error shown in output window seems a little strange: '\' before the source file name will become '/', which will cause a little inconvenient for VS to open the file by double click the error message line when the file is already opened.
PreprocessYes: '......\Console1/Source1.f90(3): error #5082: Syntax error......'.
PreprocessNo : '......\Console1\Source1.f90(3): error #5082: Syntax error......'.
The early versions I have(VS2010 + IVF2015/2012) does not have that feature.
Is it designed to? I do not think it reasonable.
