I think this is only true in C# for value types - I think the same generated code is used for all reference types, so eg. `List<object>` uses the same code as `

  well yeah. it's explained here: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/generics/generics-in-the-run-time https://docs.microsoft.com/en-us/dotnet/csharp/programming-g... btw. it's not called "runtime evaluation" and more or less a kind of runtime substitution. (because nothing gets evaluated it gets substituted) and btw. c++ allows references types to have specializations, this is not possible in c#

  This is to be expected with what are essentially pointers to heap objects. The actual code being executed only manipulates machine-word-sized values with the same semantics, so it makes little sense to have copies of the same code.

    It could be useful to duplicate it for devirtualization, and that's more likely with a JIT than compilation since it doesn't cost code size on disk.
    • jhgb 4y ago
      Well, yes. But you can't devirtualize until you know the types as well as possible, which is after "de-generifying", so as to speak (I don't really know what terminology .NET uses for this).
