Experiments with the new WASI workload in .NET 8 Preview 4

.NET 8 adds a new "wasi-experimental" workload, replacing the earlier Wasi.Sdk. This is a step towards giving .NET native, built-in support for server-side WebAssembly scenarios.

This video shows how to get started, then demonstrates how .NET+WASI creates possibilities for new kinds of apps and new ways to use .NET.

Running backend server app in a browser? You're crazy and I love it!!!

You guys are all amazing! Steve Sanderson is fast becoming a living legend (if not already!) Keep up the good work! 👍

I think the biggest deal is in docker-like containers that don't need a full os running which shrinks the overhead massively. Just abstractions of the specific OS stuff in the container.

I see your notification and I watch quickly❤

.Net 8 with Blazor newest features will be a game changer for the whole internet even desktop applications. Congratulations and thank you very much for providing it to us!

Please make more videos, weekly would be great. Daily would be amazing..

Steven, thank you and your team for the great work! Looking forward to the final result. I'm actually going to write my MSc degree work on WASM, WASI topics. Plan is to concentrate on containerization and capabilities of the technologies as Docker-alternative.

Steve, what about wasm component model support for C#? Seems like a key missing piece.

It is awesome you did this experiment Steve. That last part will get us all thinking about what could be possible....

Thanks for sharing the update on WASI. Please can you also share the font you are using as well as how you got your terminal prompt to look the way it is. Thanks

The DotNetIsolator is great. Ive been waiting for years for someone to provide a sandboxing mechanism for plugins. Hopefully that makes it out of preview.

I really like this, except I can't run .NET Wasm on due to the lack of sock_accept. I think this symbol is above and beyond the preview1 spec, is there any documentation on this?

@stevesandersonuk - What are the challenges of implementing the final example (that starts as Blazor Server then downloads the app and runs it in WASM) in real life?

[burtonrodman]

that’s some awesome stuff!! i hope nobody actually tries that heap migration for real… that sounds like a security nightmare!!
