@Bruletova__ You have the unmistakable grace of the Polish nobility. It's in your blood, not just your manners. You can only be born this way, and I see it because we share the same roots

[Ruslan @Rusco_Developer]

@Bruletova__ Take care! I really hope your family is okay

@Tech_girlll I don’t think a language exists that meets all the requirements as being fast, simple, productive at the same time

.NET 10 and C# 14 will be released tomorrow

It's one of the best releases in recent years 👇

.NET 10 is a Long-Term Support (LTS) release.
It will receive three years of support until November 14, 2028

This makes it a solid choice for production applications that need long-term stability.

The biggest addition in .NET 10 is support for file-based apps. This feature changes how you can write C# code for scripts and small utilities.

Traditionally, even the simplest C# application required three things: a solution file (sln), a project file (csproj), and your source code file (*.cs).

You would then use your IDE or the dotnet run command to build and run the app.

Starting with .NET 10, you can create a single *.cs file and run it directly:
𝚍𝚘𝚝𝚗𝚎𝚝 𝚛𝚞𝚗 𝚖𝚊𝚒𝚗.𝚌𝚜

This puts C# on equal with Python, JavaScript, TypeScript and other scripting languages.

Tomorrow, I'll share with 16,350+ people in details:

➡️ What's New in .NET 10
➡️ What's New in C# 14
➡️ What's New in ASP .NET Core in .NET 10
➡️ What's New in EF Core 10
➡️ Other Changes in .NET 10

Not sure who needs to hear this. The reason I'm so big on fine-grained rendering and signals is it turns all state into external stores. You write things locally but updates happen outside of the rendering. Components don't matter.

𝗥𝗘𝗦𝗧 𝗔𝗣𝗜 𝗕𝗲𝘀𝘁 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲𝘀 𝗶𝗻 𝟮𝟬𝟮𝟱

I've built 100+ APIs, here's what I learned 👇

Most developers struggle with REST API design.

𝟭. 𝗥𝗘𝗦𝗧 𝗠𝗮𝘁𝘂𝗿𝗶𝘁𝘆 𝗟𝗲𝘃𝗲𝗹𝘀
Level 0: Single endpoint (❌ avoid)
Level 1: Multiple resources
Level 2: ✅ Proper HTTP methods
Level 3: HATEOAS (when needed)

𝟮. 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲 𝗡𝗮𝗺𝗶𝗻𝗴
✅ Use nouns: /users, /orders
❌ Avoid verbs: /getUsers, /createOrder
✅ Be consistent: user-profiles or product-carts
❌ Avoid: UserProfiles, userProfiles

𝟯. 𝗛𝗧𝗧𝗣 𝗠𝗲𝘁𝗵𝗼𝗱𝘀 & 𝗦𝘁𝗮𝘁𝘂𝘀 𝗖𝗼𝗱𝗲𝘀

Methods:
• GET → Read
• POST → Create
• PUT/PATCH → Update
• DELETE → Remove

Success Codes:
• 200: Success
• 201: Created
• 202: Accepted (async)
• 204: No Content

Error Codes (client):
• 400: Bad Request
• 401: Unauthorized
• 403: Forbidden
• 404: Not Found
• 422: Validation Failed

Error Codes (server):
• 500: Internal Error on Server
• 503: Service Unavailable

𝟰. 𝗔𝗣𝗜 𝗩𝗲𝗿𝘀𝗶𝗼𝗻𝗶𝗻𝗴
Choose one:
• URI: /api/v1/users ✅
• Header: X-Api-Version
• Media Type: application/vnd.api.v1+json
• Query String: ?version=1 (avoid)

𝟱. 𝗥𝗲𝗾𝘂𝗲𝘀𝘁/𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗲 𝗕𝗲𝘀𝘁 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲𝘀
• Always use JSON
• Standardize error responses
• Support filtering & pagination
• Document with OpenAPI/Swagger

𝟲. 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗖𝗵𝗲𝗰𝗸𝗹𝗶𝘀𝘁
✅ HTTPS everywhere
✅ OAuth2/JWT auth
✅ Rate limiting
✅ Input validation
✅ Response caching

The key? Keep it simple and consistent.

@laforge_toma @realLehre Reactive forms should be replaced with Signal forms and even http get calls should use httpResource api to get consistent with declarative/reactive approach

.𝗡𝗘𝗧 𝟵 𝗶𝘀 𝗳𝗮𝘀𝘁𝗲𝗿 𝘁𝗵𝗮𝗻 𝗝𝗮𝘃𝗮, 𝗚𝗼, 𝗣𝘆𝘁𝗵𝗼𝗻, 𝗡𝗼𝗱𝗲𝗝𝘀 𝗮𝗻𝗱 𝗣𝗛𝗣

Why .NET is the best platform in build projects in .NET 2025

Why is .NET so fast?

- 𝗔𝗱𝗮𝗽𝘁𝗶𝘃𝗲 𝗦𝗲𝗿𝘃𝗲𝗿 𝗚𝗖 adjusts in real time, reducing pause frequency and sustaining throughput during traffic spikes.

- 𝗦𝗺𝗮𝗿𝘁𝗲𝗿 𝗝𝗜𝗧 trims warm‑up time and accelerates hot methods, producing consistently shorter response cycles.

- 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝘃𝗲𝗰𝘁𝗼𝗿𝗶𝘇𝗮𝘁𝗶𝗼𝗻 leverages AVX10 and Arm SVE, letting loops process multiple data points per tick.

- 𝗡𝗮𝘁𝗶𝘃𝗲 𝗔𝗢𝗧 further cuts binaries and startup cost, ideal for containers, IoT, and edge workloads.

- 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗲𝗱 𝗻𝗲𝘁𝘄𝗼𝗿𝗸𝗶𝗻𝗴 improves socket handling and HTTP/3 support, delivering lower latency for high‑connection services.

- 𝗙𝗮𝘀𝘁𝗲𝗿 𝗝𝗦𝗢𝗡 processing in System.Text.Json reduces allocation, enabling leaner APIs and real‑time data streams.

- 𝗟𝗼𝘄𝗲𝗿 𝗮𝗹𝗹𝗼𝗰𝗮𝘁𝗶𝗼𝗻𝘀 via spans, inline arrays, and pooled buffers lighten GC pressure and memory footprint. 🧩

- 𝗧𝗵𝗿𝗲𝗮𝗱‑𝗽𝗼𝗼𝗹 logic minimizes contention, ensuring asynchronous operations remain smooth under mixed loads.

- 𝗘𝗻𝗵𝗮𝗻𝗰𝗲𝗱 𝗺𝘂𝗹𝘁𝗶𝘁𝗵𝗿𝗲𝗮𝗱𝗶𝗻𝗴 schedules tasks more evenly, unlocking full core capacity for parallel workloads.

- 𝗖𝗿𝘆𝗽𝘁𝗼𝗴𝗿𝗮𝗽𝗵𝘆 𝗿𝗼𝘂𝘁𝗶𝗻𝗲𝘀 are streamlined, providing robust security without incurring excessive computational overhead.

- 𝗖𝗹𝗼𝘂𝗱‑𝗻𝗮𝘁𝗶𝘃𝗲 tooling reduces cold starts and aligns neatly with Kubernetes, simplifying microservice deployment.

- 𝗙𝗶𝗹𝗲 𝗜/𝗢 now buffers intelligently, boosting throughput for applications that read or write extensive data.

- 𝗥𝗲𝗳𝗹𝗲𝗰𝘁𝗶𝗼𝗻 𝗮𝗻𝗱 𝗘𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻 pathways are optimized, cutting overhead for dependency injection and dynamic object scenarios.

- 𝗠𝗶𝗻𝗶𝗺𝗮𝗹 𝗔𝗣𝗜𝘀 advance performance in .NET 9, pairing concise code with leading throughput, making .NET 9 more than 15 % faster

.NET 9 outruns these 10 popular web frameworks:

- Java (Spring) – about 2.5× slower

- Go (Fiber) – 1.3× slower

- Node.js (Fastify) – 4× slower

- Python (FastAPI) – 10× slower

- Ruby (Rails) – 20× slower

- PHP (Laravel) – 15× slower

- Kotlin (Ktor) – 2.8× slower

- TypeScript (Deno) – 3.5× slower

- Swift (Vapor) – 2× slower

- Elixir (Phoenix) – 1.7× slower

You will find links to the benchmarks in the comments.

@DerLandskn3cht @TheIgorSedov Signal API was stabilized only in Angular 20. So it takes some time move forward with Signals

[🦋 Alex Rickabaugh @synalx]

We just hit a milestone in our exploration of signal-based forms in Angular - our prototype is now merged into the main repository.

This opens the door for some important next steps like compiler integration & interop w/ existing forms.
