.NET 11 Performance and ASP.NET Core Patterns
Coverage includes EF Core 10 queries, OAuth2 across app types, asynchronous validation, HTTP resilience, MCP servers, and concurrency choices.
Jasen's top three picks
- 1 std::call_once vs. std::async
devblogs.microsoft.com
A useful follow-up on one-time initialization, especially where async work tempts developers to use a broader mechanism than necessary.
- 2 Legacy Code Is Not a Rewrite Problem

The valuable angle is operational: AI assistance can improve an old MVC codebase without turning a rewrite into the default plan.
- 3 Performance Improvements in .NET 11
devblogs.microsoft.com
Runtime performance posts are dense, but they reveal the cumulative improvements application code gets simply by moving forward.
Editor's note
I put this varied batch together with a close look at the .NET 11 performance work, since runtime details repay careful reading. The EF Core 10 overview is also worth comparing against the ASP.NET Core pieces on validation and resilient HTTP calls. There is practical ground here too, from legacy MVC work with Claude Code to choosing optimistic or pessimistic concurrency.
