The Project Designer or Project Properties UI also provides a way to target different platforms with your project.
Target platforms in the Project Designer or Project Properties UI The solution-level platform is shown in the Active solution platform dropdown, and the table shows the project-level platform for each project. To see both project-level platform and solution-level platform settings, open Configuration Manager and note the two platform settings. When you choose x86 as the solution configuration, Visual Studio selects the Win32 platform for C++ projects. C++ projects use Win32 and 圆4, but the solution platforms use x86 and 圆4.
Visual Studio considers both project-level platforms and solution-level platforms, and the project platforms come from the language-specific project systems. The Win32 platform name is used for C++ projects, and it means x86.
