Why does Visual Studio need its own runtime?

Question

visual studio

I can't understand why I need my own runtime for Visual Stuio. Why didn't Microsoft make an IDE along with a regular plus compiler like gcc?
It is somehow strange that for everything there is a standard C ++ class / function from Mikes (for example, std:: string and System:: String)

Answer 1

Are you confusing C++ with C++/CLI?
C++/CLI made to make it easier to interact with dotnet

Answer 2

This runtime is libraries for .Net
It had to be filed when MS made C# and .Net. For some reason, they didn't decide to copy libc++ there.
In C ++, support for this goodness was added so that there would be compatibility and more programmers would write using Microsoft's technology.
It only works in c++ if you ask visual studio to compile under the common language runtime.

Answer 3

std::string is the same part of the Microsoft runtime (standard library) if you are building a project in MSVS.
There are no standard implementations of the compiler and libstd++, there is a standard that describes what the implementation should be. And there are many implementations.
