.NET programming with C++/CLI
By default, CLR projects created with Visual Studio 2015 target .NET Framework 4.5.2. You can target .NET Framework 4.6 when you create a new project. In the New Project dialog, change the target framework in the dropdown at the top middle of the dialog. To change the target framework for an existing project, close the project, edit the project file (.vcxproj), and change the value of the Target Framework Version to 4.6. The changes take effect the next time you open the project.
In Visual Studio 2017, the default target .NET Framework is 4.6.1. The Framework version selector is at the bottom of the New Project dialog.
