I would like to proceed with a public publishing of a GNU General Public License version 2 application that I migrated from Visual Studio 6.0 to Visual Studio 2015.
Why did you link to that thread? It says the same as nothing.
So long as you abide by the rules and regulations to the GNU General Public License[link to GPL text] agreement as well as your Windows Store Developer Agreement[link to WSDA text]
Using a compiler that links against a non-GPL runtime should not constitute a breach in the GPL, since it does not create a derivative work. It's merely the mechanism the compiler has to produce executable code. Even if it did, in this case it wouldn't matter because OP is the one licensing under the GPL. Someone can't breach the license of their own IP, even if they do things forbidden by the license.
