Understanding Dependency Injection Lifecycles in .NET Core

Understanding async & await in C# Working with long-running operations (like API calls, database queries, or file I/O) can easily block your main thread — and that’s where asynchronous programming comes in! Here’s a simple example of how async and await help you write non-blocking, cleaner code async Task DoSomethingAsync() { Task<int> longRunningTask = LongRunningOperationAsync(); // Do independent work while the task runs DoSomethingCool(); // Await the result int result = await longRunningTask; Console.WriteLine(result); } async Task<int> LongRunningOperationAsync() { await Task.Delay(1000); // Simulate work for 1 sec return 1; } 💡 Quick Tips for async/await: • ✅ Start early, await later – begin tasks before awaiting results • ⚡ Never block the main thread – keeps UI responsive and APIs fast • 🧠 Completed tasks run instantly – no unnecessary waiting Asynchronous programming isn’t just about performance — it’s about efficiency and scalability in modern .NET applications. #dotnet #csharp #dotnetcore #asyncawait #developers #coding #programmingtips #softwareengineering

🚀 Happy Tuesday, everyone! 🚀 Today, let's delve into the world of .NET and explore some best practices for building scalable applications with C#. 1️⃣ **Asynchronous Programming**: Leverage `async` and `await` keywords to improve the responsiveness of your applications. This helps to keep your UI fluid and reduces blocking calls. 2️⃣ **Dependency Injection**: Utilize built-in dependency injection in ASP.NET Core to manage service lifetimes and enhance testability. It fosters better code structure and easier maintenance. 3️⃣ **Entity Framework Core**: Use EF Core for data access. It simplifies CRUD operations and supports LINQ queries, making database interaction more intuitive. 4️⃣ **Logging**: Implement structured logging using libraries like Serilog or NLog. This can greatly aid in debugging and monitoring the health of your applications. 5️⃣ **Unit Testing**: Write unit tests to ensure your code works as intended. Frameworks like xUnit or NUnit can help keep your codebase reliable and resilient to changes. Taking time to incorporate these practices will uplift your .NET applications and create a more maintainable codebase. What are some of your go-to .NET tips?

Ever noticed those little square brackets [ ] above your C# code? They’re not decorations — they’re attributes, and they quietly control how your app behaves. Think of them as machine-readable comments: metadata that compilers, frameworks, or tools can act on. Here are 5 attributes every C# dev bumps into early 👇 1️⃣ [Obsolete] - Mark Old Code Warns (or errors) when someone calls a method you don’t want used anymore. 👉 Safer migration path without instantly breaking builds. 2️⃣ [Required] - Validate Input Used in ASP.NET Core models. Blocks requests if the required data is missing. 👉 Saves you from writing repetitive if checks. 3️⃣ [Range] - Check Boundaries Ensures values fall between limits (e.g., 1–100). 👉 Cleaner validation without boilerplate. 4️⃣ [FromBody] / [FromQuery] - API Parameters Tell ASP.NET Core exactly where to grab values from. 👉 Eliminates ambiguity and debugging pain. 5️⃣ [NonSerialized] - Skip in Serialization Prevents sensitive or unnecessary fields from being serialized. 👉 Avoids leaking secrets or bloating data. ✨ Follow me here on LinkedIn for quick .NET breakdowns. 📖 And on Medium for deeper articles: https://lnkd.in/g5KhMWc3 #DotNet #CSharp #AspNetCore #DotNetDevelopers #CleanCode #SoftwareDevelopment #CodingTips #BackendDevelopment #Programmers #LearnDotNet

💡 Understanding the Difference: Variable Address, Value & Reference As a developer, we often use variables daily — but do we really understand what’s happening behind the scenes? 🤔 Ever wondered what really happens behind the scenes in memory? 🤔 🔹 Value: Actual data stored → int a = 10; 🔹 Address: Memory location → &a 🔹 Reference: Another name for same memory → ref int r = ref a; Understanding this difference helps us write cleaner, more efficient, and bug-free code. #DotNet #CSharp #ProgrammingConcepts #Developers #CodingTips #LearnToCode #DotNetDeveloper #SoftwareDevelopment

🚀 .𝗡𝗘𝗧 𝗗𝗮𝗶𝗹𝘆 – 𝗗𝗮𝘆 𝟴 💡 Did you know that C# generics let you write reusable, type-safe code without sacrificing performance? Using generics, you can create classes, methods, or interfaces that work with any data type while maintaining compile-time type safety, avoiding boxing/unboxing overhead. ✅ 𝗪𝗵𝗲𝗻 𝘁𝗼 𝘂𝘀𝗲:  • When building reusable components that operate on multiple types (e.g., collections like List<T>, repositories, or utility methods).  • For type-safe data structures or algorithms (e.g., generic stacks, queues, or sorting methods).  • When you want to avoid casting or boxing in performance-critical code. ⚠️ 𝗪𝗵𝗲𝗻 𝗡𝗢𝗧 𝘁𝗼 𝘂𝘀𝗲:  • If the logic is highly specific to one type and doesn’t benefit from generalization.  • When generics make the code overly complex or hard to read for minimal reuse.  • If runtime type reflection is needed — generics are resolved at compile time. 🧠 𝗤𝘂𝗶𝗰𝗸 𝗧𝗶𝗽: Use generic constraints (where T : constraint) to restrict types and enable specific operations, like requiring a class, interface, or constructor. 🔥 𝗞𝗲𝘆 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆: Generics provide type safety and performance for reusable code. Use them with constraints to balance flexibility and control in your .NET apps. ❓ What’s the most creative way you’ve used generics in your C# projects? #dotnet #csharp #generics #typesafety #dotnetdaily #cleancode #codetips #performance #programming #developers

⚡Compiler-Friendly Code: Sealed Keyword in .NET C# 🔒 When we write code, we think in logic, readability, and design. But the compiler thinks in performance, execution, and optimization. Bridging that gap is important because even a small keyword can change how the compiler sees your work. One of the most underrated examples? 👉 the sealed keyword in .NET C# In this article, I break it down into simple, digestible parts: ⭐ What is sealed? A refresher on what it really means for classes and methods. ⭐ How the compiler thinks differently Why the JIT compiler can optimize sealed code more efficiently than we might expect. ⭐ Performance advantages Faster method calls, reduced virtual table lookups… small hints that lead to noticeable impact. ⭐ Cleaner code and maintainability Protecting your design by preventing unnecessary or harmful inheritance. ⭐ Common pitfalls Cases where sealing might restrict future flexibility more than it helps. ⭐ Best practices Guidelines for when to apply sealed — and when not to. ⭐ Real-world scenarios Examples you may have already faced in your day-to-day coding. ⭐ A mindset shift Learning to “think like the compiler” — because once you do, your coding decisions change. I wrote this article with both theory and practice in mind so you don’t just learn what it does, but also why it matters and when it matters. Now I’d love to hear from you 👇 👉 Do you use sealed actively in your projects? 👉 Or is it one of those keywords you only notice when reading someone else’s code?

Object Reference Not Set… to Peace of Mind 😂 You start your day feeling confident… until the moment you see that legendary message: “Object reference not set to an instance of an object.” Ah yes, our oldest enemy. The true constant in life. Then you fix one query, and suddenly EF decides your LINQ can’t be translated anymore. You don’t know whether to refactor it, rewrite SQL, or just switch careers. And let’s not forget the joy of dependency injection; because if you can inject 15 services into a single class and still make it run, you’re not just a developer… you’re a magician. 🎩✨ To every C# dev out there: We may live in exceptions, but we handle them with pride.😎 #DotNet #CSharp #DeveloperHumor #ProgrammingLife #SoftwareEngineering #TechHumor

💡 Dependency Injection in .NET Ever wondered why every .NET project uses Dependency Injection (DI)? It’s not just a buzzword — it’s what keeps your code clean, flexible, and testable. 🔍 What is DI? Instead of creating objects manually inside your class, you inject them from the outside — and .NET does the heavy lifting for you. 💪 builder.Services.AddScoped<IEmailService, EmailService>(); Now .NET automatically provides EmailService wherever IEmailService is needed. No new keyword. No tight coupling. Just clean code. 🚀 Why It’s Awesome: Easier to maintain Easier to test Follows SOLID principles Makes large projects simpler to manage 🧠 In short: Dependency Injection helps your app grow without turning into spaghetti code 🍝 #dotnet #csharp #aspnetcore #programming #developerlife #backenddeveloper #softwaredevelopment #cleanarchitecture #coding #learning

Debugging isn’t just a skill - it’s a mindset. As .NET developers, we often face tricky issues: memory leaks, async deadlocks, or that one bug that only appears in production. What really matters is not just knowing the framework, but having the problem-solving attitude to dig deeper: • Reproduce systematically 📝 • Break problems into smaller parts 🔄 • Question assumptions 🤔 • Use the right tools (Visual Studio diagnostics, logging, performance profilers, Graylog, etc.) The best developers I’ve worked with aren’t the ones who never hit bugs - they’re the ones who stay calm, think clearly, and solve them efficiently. 👀Curious to know: What’s your go-to strategy when you’re stuck debugging in .NET? #dotnet #csharp #problemsolving #debugging #softwareengineering
