    Project mention: .NET 6 Preview 1 Released | reddit.com/r/programming | 2021-02-17

    Yeah, I wonder how this announcement plays into that. There's been a wiki page regarding limitations for a long time, and I wouldn't be surprised if the realization was that an entirely different approach to EnC was in order.

  • GitHub repo VsVIM

    Vim Emulator Plugin for Visual Studio 2015+

    Project mention: Vim and Vim Emulators | dev.to | 2020-11-18

    The three main Vim emulators I've used are VsVim for Visual Studio, VSCodeVim, and IdeaVim. I've had generally good experiences with all of them, and they can all effectively emulate the main features of Vim that I find useful. As long as I can use the standard motions and keybindings and create some simple imap and nmap rules, I'm happy. If the emulator supports macros and relative line numbers that's even better.

    Project mention: Anyone else having issues compiling their project into a single file when targeting .NET Core 3.1 or .NET 5? | reddit.com/r/csharp | 2021-02-23

    Not just Windows, they're self extracting files with dotnet 5 and earlier for all OSes. I've also found that some native libs don't get bundled into the single file all the time - see this issue: https://github.com/dotnet/sdk/issues/14489

    I have some more samples in the other folders, and I will also include some snippets in the updated docs (need to finish writing them and include them in the dev branch). Here's a couple examples:

    Super simple, complete examples of a shader that just multiplies all items in a buffer by 2: https://github.com/Sergio0694/ComputeSharp/blob/dev/samples/...

    Simple naive matrix-multiply-add shader: https://github.com/Sergio0694/ComputeSharp/blob/ada133aacd29...
