# COMMON_LANGUAGE_RUNTIME

New in version 3.12.

By setting this target property, the target is configured to build with `C++/CLI` support.

The Visual Studio generator defines the `clr` parameter depending on the value of the `COMMON_LANGUAGE_RUNTIME` target property:

Not Set (default)

> Native C++.

`""` (set but empty)

> Mixed unmanaged/managed C++ using .NET Framework.

`netcore`

  New in version 3.26.

  Mixed unmanaged/managed C++ using .NET Core.

  This required VS 2019's v142 toolset or higher.

`pure`

> Managed C++.

`safe`

> Managed C++.

This property is only evaluated Visual Studio Generators for VS 2010 and above.

To be able to build managed C++ targets with VS 2017 and above the component `C++/CLI support` must be installed, which may not be done by default.
