Not strange at all, apparently many still aren't aware that C++/CLI exists.

CLR was designed from the start to support C++.

Back in the 2000, "Everything.NET" Microsoft, there was the goal of having everything on top of .NET, it just did not play out that way due to the endless Windows/Office vs .NET politics across MS teams.

Using C++/CLI is much more productive for interop than manually writing P/Invoke declarations.

Or using C++/WinRT to wrap C++ API into COM/UWP libraries.

Likewise on Java, microEJ and Android world, with Android Studio, Eclipse, Netbeans and Oracle Studio you can easily do mixed language development and debugging with C and C++.

Any systems programming language that wants a place at the table on these platforms, needs to cover these workflows as well as C++ does.
