CoreCLR VS WPF

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

Sort of, some topic are not relevant anymore, consider this - https://github.com/dotnet/coreclr/tree/master/Documentation/botr

Fairly advanced stuff but the Book Of The Runtime (BOTR) it's a invaluable resource

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

Book of the Runtime

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

Gear up, folks, and test drive this fresh-off-the-lab feature. And should you stumble upon any glitches along the way, don’t hesitate to reach out. Got a bug to report or feedback to give? Send them directly to our dotnet/wpf repository. We’re eager to hear from you, because together, we’re only going to make the experience even better!

I did some research and did not find any proof of the EOL on WPF. In fact, Microsoft just updated the roadmap on WPF 2 months ago.

There’s still room for improvement though. I should add, WPF on .NET Core consumes a lot of memory, due to a memory leak. It was logged by our COO as one of our users was doing a comparison.

have you tried this?

WPF: Licencia MIT.

Some added context: It's a side effect of how variable rendering works in UI library we use. There's currently sadly no way how to disable VRR compatibility, which causes the issue you describe unless you tell your GPU to not treat Playnite as VRR compatible. Some more info here.

WPF is definitely not dead. It may not be the latest shiny thing, but it works, it is maintained (judging by https://github.com/dotnet/wpf or https://devblogs.microsoft.com/dotnet/wpf-on-dotnet-7/), and it is fully and officially supported on the modern .NET platform.

This article only sights a video stream. I think part of the problem with the glacial pace of development is reliance on manual testing. See this comment:

https://github.com/dotnet/wpf/discussions/7130#discussioncom...

> Our primary goal is to ensure reduced turn-around-times for new PRs as well as clear the pending backlog of existing PRs. To that end, we are working on putting appropriate automation in place to reduce the dependency on manual testing as much as we can.

See also the recently updated WPF roadmap:

https://github.com/dotnet/wpf/blob/main/roadmap.md

If you look at the history of this file you can over the years tests have been always been in the backlog.

As for “where projects go to die”, they have 3 features planned for this year: Windows 11 Theming, a new type of folder browser, and null ability annotations. And they say they don’t think they can do them all. Maybe I’m underestimating, but that’s not a lot.
