Running .NET code in isolation using WebAssembly

on YouTube ↗20m

" summary

Demonstrates running full .NET assemblies inside WASI using net-isolator and the Wasmtime runtime, loading the Base Class Library and a preopened directory so the guest sees only specified files, with a console app and an Azure Function example invoking a Fibonacci wasm and .NET methods inside-process. Startup measures near 400 ms and claimed execution up to 50% faster than Docker, and shows Azure AKS WASM node pools, runwasi shims and Spin/Lunatic ecosystem pieces.
