Day 28/100 Async in .NET Core — What Actually Happens Behind the Scenes Most developers use async/await. But very few truly understand what’s happening inside ASP.NET Core when a request hits your API. Let’s simplify it 👇 🔄 What Happens When a Request Comes In? 1️⃣ A thread from the Thread Pool starts processing the request 2️⃣ Your API calls an async I/O operation (database, HTTP call, file, etc.) 3️⃣ The thread is released back to the pool while waiting 4️⃣ When the I/O completes, any available thread resumes execution 5️⃣ The response is returned to the client 💡 The Key Insight 👉 Async does NOT make your code faster. 👉 It makes your API more scalable. Why? Because threads are not sitting idle waiting on I/O. And in high-traffic systems, Thread utilization = throughput. ❌ Without Async (Blocking I/O) • Threads wait • Thread pool gets exhausted • Requests start queuing • Throughput drops ✅ With Async (Non-Blocking I/O) • Threads are released during waits • Reused for other requests • Higher concurrency • Better scalability ⚠️ The Real Production Issue Many teams use async in the controller… But somewhere in the chain: Controller → Service → Repository A sneaky .Result, .Wait(), or synchronous DB call appears. And just like that… scalability is gone. 💥 Async must be end-to-end. 🧠 Final Thought Async isn’t about raw speed. It’s about efficient thread usage under load. If you’re building high-traffic APIs, this distinction matters.

Fast APIs aren’t about writing endpoints — they’re about architecture and concurrency. In this short: ✔ Why FastAPI is fast ✔ How async improves throughput ✔ Real scalable architecture ✔ Working production-style code This is exactly what backend interviews test. #PythonInterview #FastAPI #BackendDevelopment #SoftwareEngineering #TechCareers

APIs are everywhere. In 2026, FastAPI is one of the best ways to build them. Clean endpoints, automatic validation, and docs for free.

FastAPI is a modern, high-performance Python web framework used to build APIs quickly and efficiently. It offers automatic documentation, fast development with type hints, and excellent speed powered by Starlette and Pydantic. Perfect for creating backend servers, REST APIs, and scalable web applications with minimal code. #python3 #pycode #learnpython

Day 26/100 Program.cs in ASP.NET Core Web API – Explained Clearly If you’re preparing for .NET interviews or building Web APIs, understanding Program.cs is very important. In modern ASP.NET Core (.NET 6/7/8), Program.cs is the entry point of the application. It is responsible for: • Creating the application • Registering services (Dependency Injection) • Configuring the middleware pipeline • Starting the web server Let’s understand the flow in a simple way 👇 🔹 1️⃣ Create the Builder Csharp var builder = WebApplication.CreateBuilder(args); This line sets up: Configuration (appsettings.json) Logging Dependency Injection container Kestrel web server Think of this as preparing the foundation of the application. 🔹 2️⃣ Register Services (Dependency Injection) Csharp builder.Services.AddControllers(); builder.Services.AddSwaggerGen(); Here we register: Controllers Swagger Database context Custom services (Repository, Business logic, etc.) This is where Dependency Injection is configured. Without registering services here, the application cannot use them. 🔹 3️⃣ Build the Application Csharp var app = builder.Build(); This creates the application instance using all the configurations and services added earlier. 🔹 4️⃣ Configure Middleware (HTTP Pipeline) Csharp app.UseHttpsRedirection(); app.UseAuthentication(); app.UseAuthorization(); app.MapControllers(); Middleware defines how: Request → Process → Response Important: Middleware order matters. For example: Authentication must come before Authorization. 🔹 5️⃣ Run the Application Csharp app.Run(); This starts the Kestrel server and begins listening for incoming HTTP requests. 🔥 Complete Flow in One Line: Create Builder → Register Services → Build → Configure Middleware → Run

We’ve all heard the term API before, but what does it mean? Why are there so many different types, and what do they all do? This video seeks to answer those question by diving a little bit deeper into what things like GraphQL, RESTful APIs, Websockets, and Webhooks do. APIs are extremely important, so it’s crucial to have a high level understanding, so during implementation you know which would be best suited for your needs.
