Using WebAssembly from .NET with Wasmtime
Wasmtime, the WebAssembly runtime from the Bytecode Alliance, recently added an early preview of an API for .NET Core, Microsoft’s free, open-source, and cross-platform application runtime. This API enables developers to programmatically load and execute WebAssembly code directly from .NET programs. Although .NET Core is already a cross-platform runtime, there are good reasons for .NET developers to take a closer look at WebAssembly, as Peter Huene demonstrates in this post.
Multi-Value All The Wasm!
Multi-value is a proposed extension to core WebAssembly that enables functions to return many values, among other things. It is also a prerequisite for Wasm interface types. Nick Fitzgerald has been adding multi-value support all over the place recently, started with the Rust and WebAssembly toolchain. Next he added support to the Wasmtime runtime, and the Cranelift code generator it’s built on top of. Here's his account of the journey.
Debugging WebAssembly Outside of the Browser
WebAssembly has begun to establish itself outside of the browser via dedicated runtimes like Mozilla’s Wasmtime and Fastly’s Lucet. While the promise of a new, universal format for programs is appealing, it also comes with new challenges. At Mozilla, we’ve been prototyping ways to enable source-level debugging of .wasm files using existing tools, like GDB and LLDB.
