It has been a deliberate decision. The Book of the Runtime documentation states "The goal of the CLR is to make programming easy" and acknowledges there are faster alternatives out there. When I have asked insiders why there isn't a bigger focus on performance, the response is essentially that if performance is really important you should use C++.

That point of view is outdated.

Hence Roslyn, .NET Native with VC++ backend, value types improvements and safer pointers in 7.x.

There are even plans to slowly move parts of the runtime from C++ into C#, now that .NET Native is a thing.

" So, in my view, the primary trend is moving our existing C++ codebase to C#. It makes us so much more efficient and enables a broader set of .NET developers to reason about the base platform more easily and also contribute"

Java seems to have a similar initiative called "Project Metropolis" to (re)write some stuff in Java instead of C++: http://mail.openjdk.java.net/pipermail/discuss/2017-Septembe...

In case anyone else is interested, that quote comes from https://github.com/dotnet/coreclr/blob/master/Documentation/...
