ASP.NET Core, MAUI, and async internals

A varied .NET roundup with API validation, YARP reverse proxies, Azure multi-tenant architecture, MAUI, and performance guidance.

Jasen's top three picks

1
.NET Digest #7
Medium

A quick digest opener to set the tone for the rest of the issue.
2
C# Best Practices: Writing Clean, Efficient, and Maintainable Code
Medium

Solid C# guidance here, especially the piece on avoiding exceptions for control flow.
3
Mastering Reverse Proxies in ASP.NET Core: A Beginner’s Guide to YARP
Medium

YARP and cross-cutting concerns make a nice one-two for ASP.NET Core builders.

Editor's note

I kept this issue deliberately mixed, with practical API work, architecture, performance, and mobile content side by side. The YARP primer and the Minimal APIs validation piece are both useful if you’re building modern ASP.NET Core services, while the async/await and thread-pool articles reward anyone who likes to understand the runtime a little better.
