Fatal Error C1210
/clr:pureand/clr:safeare not supported by the version of the runtime installed
The /clr:pure and /clr:safe compiler options are deprecated in Visual Studio 2015 and unsupported in Visual Studio 2017.
C1210 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 C1210, 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This error is obsolete in Visual Studio 2022 and later versions.
