おはよう！

In my little corner of the #dotnet developer world there seems to be a bit of a renaissance happening. We have @AvaloniaUI and @UnoPlatform both achieving incredible stability, feature sets and performance! I'm seeing @wieslawsoltes churning out amazing UI tooling! We have @KDCoder building a whole 2D game developer framework! It's so inspirational! Is there anything similar I should also be looking at??

We're happy to see more .NET developers getting access to ReSharper's coding intelligence. The engine behind Rider’s C# experience is now available in @code and other compatible editors.

literally me to every YouTuber and 98% of you posting on here 🤣

For all the pufferfish fans, I’m so sorry that I couldn’t fix the audio on TikTok😔🤞 I hope that you can enjoy from twitter!

Finally decided to start a YouTube channel! Would greatly appreciate if you went and checked it out 🫶 First video: how to fully customize Windows Terminal with Oh My Posh (and more!) Also let me know if you want to see any specific videos from me! 💖 youtu.be/VFnr0lwwGuQ?si…

Since Entity Framework 10 we have support for Named (and Multiple) Query Filters 🥳 #dotnet

the hard thing about product design is making complex things look simple.

AI in .NET is way easier than people think. And you can start for free. If you want a practical first project, build vector search: - Turn text into embeddings (vectors) - Store them in your vector store (pg_vector) - Turn the user’s query into a vector - Compare with cosine similarity to find the closest matches That’s why it feels like “search by meaning” instead of keywords. To do this cleanly in .NET, start with MEAI (Microsoft Extensions AI), the official library for LLM + embeddings.

The best HttpClient config is the one you don’t repeat in every service. In .NET, you set it up once with IHttpClientFactory (and Aspire if you’re using it): - Discovery for service-to-service calls - Resilience defaults so transient failures don’t hurt you Then you just inject the client and write business code.

wow i love pixel art

I see this mistake in almost every codebase I review. Developers awaiting async calls one by one: var user = await GetUserAsync(); var orders = await GetOrdersAsync(); var stats = await GetStatsAsync(); Each await waits for completion before starting the next. 3 calls at 200ms each = 600ms total. You should learn about Task.WhenAll(). var userTask = GetUserAsync(); var ordersTask = GetOrdersAsync(); var statsTask = GetStatsAsync(); await Task.WhenAll(userTask, ordersTask, statsTask); Now your total wait time = the slowest task. 600ms becomes ~200ms. I use Task.WhenAll() whenever I have: - Multiple API calls that don't depend on each other - Dashboard data fetching from different sources - Notifications going to multiple channels (email, SMS, push) - Cache invalidation across multiple keys Why I love it: - No extra threads needed, just smarter scheduling - Async I/O waits for responses, doesn't block - One simple change, massive performance gain Some lessons I learned the hard way: - Only works when tasks are truly independent - If Task B needs Task A's result, you can't parallelize - For thousands of tasks, I add SemaphoreSlim for throttling Trust me, go check your codebase right now. You'll find at least one place where this applies. Join my free .NET Web API Zero to Hero Course: codewithmukesh.com/courses/dotnet… Found this useful?

What people think .NET development is: ✏️ Writing C# code 💻 Using Visual Studio 🔧 EF Core scaffolding 🚀 1-click deployments 📝 CRUD apps with minimal endpoints What it REALLY is: The iceberg runs deep 🧊 ↳ Clean Architecture & SOLID principles ↳ Domain-Driven Design ↳ Security & Authorization ↳ EF Core query optimization & transactions ↳ Scalable system designs ↳ Caching & memory management ↳ Code reviews, Git & PR quality ↳ Code coverage & testing ↳ Cost optimizations The surface-level stuff gets you started. The underwater stuff keeps you employed for decades. Which part of the iceberg are you working on right now?
