# 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 `COMMON_LANGUAGE_RUNTIME`:

- property not set: native C++ (i.e. default)

- property set but empty: mixed unmanaged/managed C++

- property set to any non empty value: managed C++

Supported values: `""`, `"pure"`, `"safe"`

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.
