Hi,
Sorry for the confusion. The ‘VisualGDB’ platform corresponds to the new MSBuild backend introduced in v5.2. The regular ‘Win32’ platform corresponds to the old-style projects that use GNU Make or CMake.
Since v5.2, we recommend using the new MSBuild backend (‘VisualGDB’ platform) for all new projects, so normally the old ‘Win32’ platform should not appear for the VisualGDB projects. If it does despite selecting MSBuild, please let us know the steps to reproduce it and we will fix it.
