C# is not a C-like language. It's a managed runtime with garbage collection.

However Mark Russinovich, CTO of Azure did say that it's time to drop C and C++

Based on the context I think by "c like" they meant languages with a culture of dealing with raw pointers. c# is c by name and curly braces, but primarily uses managed memory

Calling C# a C-like language is like saying JavaScript is a descendant of Java.

C# is a lot closer to Java if anything, should clarify to be c and c++

I think the GP probably poorly phrased that. “Memory unsafe languages” would be a better term, apart from the basic syntax C# really isn’t very C-like.

C# is C-like in syntax only.

Syntax isn't the reason why C and C++ are falling out of favor.

could be worded better but from context in the sentence I read that as c/c++
