Future Possibilities for .NET Core and WASI (WebAssembly on the Server) | OD108

WebAssembly is moving beyond the browser and is pitched to become a foundational element of modern cloud-native architecture. It lets any language compile to universal binaries that run on any OS or processor, robustly sandboxed and with great performance. This session covers a new approach to running .NET in WASI environments. You’ll see how your existing .NET code could be built into WASI-compliant modules, plus the opportunities this opens. This is experimental, not yet a committed product.
