What Does ChatGPT Mean for New Software Developers? 

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. 

In this video we perform a full step by step build of a .NET MAUI App that we test on both Windows and Android. The app interacts with a separate .NET 6 API that we also build step by step.

Issues Fixed in 15.9.23

• Fixed C++ compiler bug for proper folding of inline variable dynamic initializers. Ported from the VS 2019 16.0 release.
• Security improvements in vctip.exe.
• A change to enable Enterprise IT administrators and deployment engineers to configure tools like Microsoft Update client & SCCM to determine applicability of VS2017 updates hosted on Microsoft Update Catalog & WSUS.

Security Advisory Notices

• .NET Core Denial of Service Vulnerability 

TypeScript continues its growth journey with more and more JavaScript developers and framework authors taking advantage of the excellent tooling and productivity boost that TypeScript provides in order to create apps that scale. In this session, we talk about the Typescript journey with a focus on some of the most exciting recent features and a preview of things to come. Apart from the language and tools enhancements, see efforts already underway to bring some of the power of TypeScript to existing JavaScript projects.

We can now run ASP.NET Core applications as Windows services with minimal effort. This blog post introduces how this process is done.
