Fatal Error C1207
Managed templates not supported by the version of the runtime installed
C1207 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 C1207, install the common language runtime version that is intended for use with your compiler.
This error is obsolete in Visual Studio 2022 and later versions.
