Friend assemblies not supported by the version of the runtime installed
C1208 occurs when you have a compiler for the current release, but a common language runtime from a previous release.
Some functionality of the compiler may not work on a previous version of the run time.
To resolve C1209, install the common language runtime that shipped with the compiler you're using.
For more information, see Friend Assemblies (C++).
This error is obsolete in Visual Studio 2022 and later versions.
