Future Possibilities for .NET Core and WASI - WebAssembly on the Server

Explore the future possibilities of .NET Core and WASI (WebAssembly on the Server) in this 28-minute conference talk from Microsoft Build 2022. Dive into the world of WebAssembly beyond the browser and its potential as a foundational element in cloud-native architecture. Learn about a new experimental approach to running .NET in WASI environments, including how to build existing .NET code into WASI-compliant modules. Discover the benefits of WASI, understand the challenges of running .NET in this environment, and witness demonstrations of an experimental .NET SDK for WASI and ASP.NET Core on Sat. Gain insights into advanced ASP.NET Core features, potential pitfalls to avoid, and real-world examples of WASI hosts. This talk provides a comprehensive overview of WebAssembly's expanding role and its implications for .NET developers.
