* add property that is available in msbuild They fsharp team decided to remove a `#if MONO` with the assumption that `xbuild` is dead and everything has switched over to `msbuild`: https://github.com/Microsoft/visualfsharp/pull/3969/files#diff-bcb4028a918d13bbab2d0c1c15c97e6aL181 dotnet/fsharp@5e17e31#r151844561 which, alas, is not true yet. With this PR we started to ship above modifications in the MDK: #7018 * Bump API snapshot submodule
