💡 𝗧𝗵𝗿𝗲𝗲 Ways to Guard Against Null Arguments in C# 🛡️ 💡 𝗧𝗿𝗮𝗱𝗶𝘁𝗶𝗼𝗻𝗮𝗹 𝗶𝗳 𝗖𝗵𝗲𝗰𝗸 𝗮𝗻𝗱 𝗧𝗵𝗿𝗼𝘄 This approach uses the null-conditional operator (is) to check if the argument is null. If it is, a new 𝗔𝗿𝗴𝘂𝗺𝗲𝗻𝘁𝗡𝘂𝗹𝗹𝗘𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻 is thrown with the parameter name for clarity. 👍 𝗔𝗿𝗴𝘂𝗺𝗲𝗻𝘁𝗡𝘂𝗹𝗹𝗘𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻.𝗧𝗵𝗿𝗼𝘄𝗜𝗳𝗡𝘂𝗹𝗹 Introduced in C# 10, a more concise way to perform the same check. This method throws an 𝗔𝗿𝗴𝘂𝗺𝗲𝗻𝘁𝗡𝘂𝗹𝗹𝗘𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻 if the provided argument is null. 🔥 𝗥𝗲𝘀𝘂𝗹𝘁 𝗣𝗮𝘁𝘁𝗲𝗿𝗻 𝗜𝗺𝗽𝗹𝗲𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻 The Result pattern wraps outcomes in a type-safe structure, making it explicit whether an operation succeeded or failed. This approach is particularly useful when you need to handle multiple types of failures in a structured way. Remember that defensive programming isn't just about avoiding errors—it's about making your code robust and maintainable while providing clear feedback when something goes wrong. The Result pattern is particularly valuable when you need to handle multiple types of failures in a structured way, but it might be overkill for simple null checks. Choose based on your specific needs and team preferences. Which approach do you prefer? Share your favorite pattern in the comments below! 👇 #csharp #microsoft #dotnet #cleancode

The best C# feature in recent years? Pattern matching. Pattern matching lets you check if an object has specific characteristics: - Is null or is not null - Is of a particular type - Property has a specific value Together with switch expressions and records, you can write concise and expressive code.

🚀 .NET Interview Tip of the Day ❓ Question: 👉 What is Garbage Collection (GC) in .NET, and why is it important? ✅ Answer: In .NET, Garbage Collection (GC) is the built-in memory manager that keeps your applications efficient by automatically cleaning up objects you no longer use. 🔍 How it works: • The .NET runtime tracks objects in memory. • When an object is no longer referenced, GC reclaims that memory. • GC uses Generations (Gen 0, Gen 1, Gen 2) for efficiency, assuming short-lived objects die young. 💡 Why it matters: • ✅ Prevents memory leaks • ✅ Eliminates need for manual memory cleanup • ✅ Keeps apps stable and performant 📌 Example: MyClass obj = new MyClass(); // Once obj is out of scope, GC will reclaim it automatically. 🔑 Pro Tip: GC handles managed objects — but for unmanaged resources (files, DB connections, sockets), always implement IDisposable and use: using(var resource = new MyResource()) { ... } 👉 That way, you combine the power of automatic GC with manual resource control for rock-solid applications. ⸻ ⚡ Remember: GC makes .NET development easier, but good developers still manage resources wisely! #DotNet #CSharp #AsyncAwait #CodingTips #InterviewPrep #DotNetDevelopers #SoftwareDevelopment #WebDevelopment #BackendDevelopment #CleanCode #SystemDesign #ProgrammingTips #TechCareers #Developers #CodingLife #TechCommunity #LearningInPublic #CodeNewbie #MicrosoftDotNet

C# 14 in the preview allows the null conditional member access operator on the left-hand side of an assignment. Previously, you had to check if the customer was null before assigning the order. In C# 14, the GetCurrentOrder method is not called if the customer is null.

🚀 Today’s Post | Interview Question #36 Dependency Injection Lifecycles in .NET 🧐 Here’s your quick guide to DI in .NET Core: 🔹 Singleton ♾️ ✅ One instance for the entire application ✅ Perfect for stateless, shared services (e.g., Logger) ❌ Dangerous for storing state! 🔹 Scoped 🔄 ✅ One instance per user request (e.g., in a web app) ✅ Ideal for Entity Framework DbContexts ❌ Not thread-safe outside a request 🔹 Transient ⚡ ✅ A new instance is created every time it’s requested ✅ Great for lightweight, stateless services ❌ Can cause memory overhead if overused 💡 Quick Recap: Singleton = Shared, global state Scoped = Per user session/request Transient = Always new, never shared Mastering these lifecycles will level up your architecture and prevent nasty bugs. 🚀 👉 Which lifecycle do you use the most in your projects? 🔑 Hashtags #DotNet #DotNetCore #DependencyInjection #SoftwareArchitecture #Programming #BackendDevelopment #WebDevelopment #Microservices #Coding #SoftwareDevelopment #Tech #CodeNewbie #LearnToCode

🎯 Design Best Practices In .NET C# ✅ After working for some reasonable period of time in the Software field, day by day you would get more confident that there is still something new you are not aware of, yet. Depending on your exposure to different kinds of projects and requirements, you would harness new skills. However, in my humble opinion, the most precious skills are the Analytical and Design skills. Don’t get me wrong, we all know that at the end of the day there is some code to write and someone would eventually do it. However, writing the code is something you could learn from an online -or offline- documentation or a tutorial. On the other hand, Analytical and Design skills are different… In this article we are going to explore some Design Best Practices that are practically proved to be efficient. 🔍 Topics to Look Out For ⭐ Unified Return Object ⭐ Don’t Abuse DI/IoC/Containers ⭐ Delegating Controlling How To Fire Events ⭐ The Snapshot Structure ⭐ Immutability ⭐ Paging and Partitioning ⭐ Delegates over Func<> ⭐ String.GetHashCode Nightmare ⭐ Separate State from Behavior ⭐ Not Using IoC Containers is Not an Excuse ⭐ Wrap Static Objects & Third Parties ⭐ Best Practice When Using Timers ⭐ Avoid Code Hidden Intentions ⭐ Defining Non-Generic Interface beside the Generic One 💡 What’s one design best practice you admire the most? Don't let it stop here, repost and share ♻️ with your network to spread the knowledge ✅ https://lnkd.in/gKdas9gX #dotnet #csharp #coding #code #programming #bestpractices #devcommunity #computerscience #softwaredesign #softwaredevelopment #softwareengineering #softwarearchitecture
