Octave developers are not working with the Visual Studio staff.
In mxe-octave that is used to build octave for windows, there are some 
descriptions
for build octave for Visual C++ compiler.  
However, a main contributor related to the MSVC has not come to octave 
community recently.
You want to use Visual studio on windows you have to do a lot of things
with your best efforts. Perhaps there are no easy ways.
