WebAssembly (WASM) and WebAssembly System Interface (WASI) are opening new opportunities for developers. .NET developers became familiar with WASM when Blazor WebAssembly was released. Blazor WebAssembly runs client-side in the browser on a WebAssembly-based .NET runtime. WASI is bringing WASM out of the browser world by providing a system interface to run WebAssembly outside the web. It is a standard for how WASM modules interact with the host environment. This post will show you how to run .NET 7 on a Raspberry PI Zero 2 W using WASM and WASI.

After running a first console app on my Raspberry Pi 3, I had to try ASP.NET Core and API. Two weeks ago when I posted “.NET Core console app running on Raspberry Pi”, I could make API working, but I had no chance with MVC. Today it worked!

Now that there is a distribution of .NET Core on a Linux distro running on my Raspberry Pi 3, I had to try it.

In this post, I will explain all the steps I had to execute to be able to run my first Hello World application.
