 > The **Win32** platform name is used for C++ projects, and it means **x86**. Visual Studio considers both project-level platforms and solution-level platforms, and the project platforms come from the language-specific project systems. C++ projects use **Win32** and **x64**, but the solution platforms use **x86** and **x64**. When you choose **x86** as the solution configuration, Visual Studio selects the **Win32** platform for C++ projects. To see both project-level platform and solution-level platform settings, open **Configuration Manager** and note the two platform settings. The solution-level platform is shown in the **Active solution platform** dropdown, and the table shows the project-level platform for each project.
