Here is the project
I had to strip it off to fit in
JWasm targets must be in place:"C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations"
If you want to add include files it should be done through:
Project->Property Pages->Cnfiguration Properties->JWasm->General->Include Paths
To have syntax highlighting you need the Usertype.dat (you can modifie it if you want, I added more data)
Usertype.dat goes in to: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE
To use it you have to do:Options->Text Editor->File Extension->Microsoft Visual C++
in the Extension box type:ASM
I use VC13 because it is easy to debug it with Visual Studio Debugger
and also easy to combine C with ASM
If you want to build 32-bit source you select Win32 from the Toolbar or in Configuration Manager
You need also to change it in:
Project->Property Pages->Cnfiguration Properties->JWasm->Object File->Object Format->COFF 32-bit (/coff)
