  • The Performance Impact of C++'s `final` Keyword

    Yes, that is true. I'm not sure about JVM implementation details but the reason the comment says "virtual and interface" calls is to outline the difference. Virtual calls in .NET are sufficiently close[0] to virtual calls in C++. Interface calls, however, are coded differently[1].

    Also you are correct - virtual calls are not terribly expensive, but they encroach on ever limited* CPU resources like indirect jump and load predictors and, as noted in parent comments, block inlining, which is highly undesirable for small and frequently called methods, particularly when they are in a loop.

    * through great effort of our industry to take back whatever performance wins each generation brings with even more abstractions that fail to improve our productivity

    After that you can check out the The Book of the Runtime, which is the CoreCLR version of the previous book.

    Technically the restrictions already exist, just as a part of the development experience.

    - .NET Hot Reload is only implemented on Windows. It requires support in the .NET runtime, which is technically possible to implement, but the team has not gotten around to implementing it for years. This doesn't have to do with the issue around MS removing the "dotnet watch" command, it's for the "Edit and Continue" feature in IDEs.[1][2]

    - MS was considering deprecating Omnisharp, the open-source language server that implements C# support for VS Code, and replacing it with a closed-source version. Since the announcement, commits to omnisharp-vscode have dropped off significantly. The lack of Omnisharp would mean there would be no real open-source C# development environment for Linux anymore, since MonoDevelop was abandoned a few years ago. [3]

    The next step is to realize everything you think you know about .NET is just an abstraction. Next step is to learn about what is going on behind all that syntax sugar and facades. 1st step might be https://github.com/dotnet/coreclr/tree/master/Documentation/botr then go down the rabbit hole and have fun

    As for the books, back in the days I really enjoyed reading “CLR via C#" by Jeffrey Richter which helped a lot to understand what is under the hood. Other from that, try The Book of the Runtime
