It depends on what you call "care about". Yes a C runtime is used when 
loading libvlc. But I don't think it's ever propagated to the C# layer.

And on Windows it's possible mix C runtimes. For example you can link 
your an app with runtime with some debug features (msvcrtd.lib or 
msvcurtd.lib) that doesn't mean everything you load will also use the 
same runtime. For example advapi32.dll will still use msvcrt.dll and 
work as expected. There are limits to how you can mix MSVC runtimes 
(https://docs.microsoft.com/en-us/cpp/c-runtime-library/potential-errors-passing-crt-objects-across-dll-boundaries?view=vs-2019) 
it's used all the time as long as you respect certain rules, which we 
did so far.
