🧠 How do you add new logic in .NET — without touching existing code? This blog breaks down the Open/Closed Principle (OCP) with a tax calculation example in C#. ✅ Add new business rules and logics ✅ Keep current logic untouched ✅ Use DI + Factory + Interface combo Less regressions. More testability. Cleaner code. 🔗 Read now: https://ilovedotnet.org/blogs/open-closed-principle-in-solid

Is your repository interface violating SOLID? If you're forcing consumers to depend on unused methods, you're breaking the Interface Segregation Principle. 💡 In this blog, I show how to fix it by splitting IGenericRepository<T> into: IReadableRepository<T> 📖 IWritableRepository<T> ✍️ ✅ Cleaner code ✅ Lower coupling ✅ Easier testing 🔗 Read the full blog: https://ilovedotnet.org/blogs/interface-segregation-principle-in-solid/

Git Pre-commit hooks execute before a commit is made and can enforce coding standards, format code or run tests and enforce code coverage. Automating the setup of these hooks ensures consistency across a team, removing the need for manual configuration. This makes maintaining standards across different developer machines especially in large teams. In this article, we'll explore how to automate the setup of a pre-commit hook in a .NET project using MSBuild. Check out https://ilovedotnet.org/blogs/automating-git-hook-setup-in-dotnet-with-msbuild for more details and code samples

FluentAssertions Went Paid. What Did I Do? I Migrated 1000+ Tests in Seconds! January 2025 started with a surprise—FluentAssertions, the popular free assertion library for .NET, is now paid. At $130 per developer, our enterprise (1000+ devs) decided it wasn’t worth the cost. That’s when I had a realization: 💡 Over a decade, I had unknowingly introduced technical debt by relying on FluentAssertions in every project I worked on. So, I took action. I wanted a fast, automated way to migrate every test to xUnit assertions. First, I tried LLMs (Ollama)—worked for a single assertion but became slow for large-scale repo migration. Then, I switched to Regex. ⚡ Boom! In seconds, my entire repo (1000+ test methods) was converted. ✅ 90%+ automated conversion ✅ Manual cleanup took just an hour ✅ Now, we’re FluentAssertions-free Lesson learned: Choose dependencies wisely. Even the best free tools can turn paid. If you’ve been using FluentAssertions, it’s time to rethink. Would you pay $130 per dev or migrate? Let me know your thoughts! 👇💬 Check https://ilovedotnet.org/blogs/using-regex-to-migrate-from-fluent-assertions-to-xunit-assertions for idea and code sample!!

Ever wondered how to add new behavior to existing classes without modifying them? 🤔 Learn the Visitor Pattern—one of the most powerful design patterns in object-oriented programming. Why should you care? ✅ Helps keep your core classes clean ✨ ✅ Enables adding operations without modifying existing code 🔥 ✅ Follows the Open-Closed Principle (OCP) in SOLID Here’s a simple analogy: Imagine you own a mall 🏬. Customers (elements) visit the mall, and different staff members perform different tasks: Security checks the customer’s ID 🛂 Sales staff offer discounts 🏷 Customer service gathers feedback 💬 Each staff member is like a Visitor, performing a specific operation without changing the customer! 🎯 Check out https://ilovedotnet.org/blogs/behavioral-design-pattern-visitor/ for code samples and in browser demo.

🚀 Adding a distributed lock to Hosted Background Service in ASP.NET WEB API 🔹 What? We needed to query AWS Athena every hour to fetch analytics data for a dashboard. Running it as a background service worked, but multiple API instances triggered duplicate queries, causing AWS rate limits. 🔹 Why? Errors and warnings skyrocketed, increasing costs and inefficiency. The challenge worsened when the query frequency was reduced to 30 minutes. 🔹 How? We implemented a distributed lock using a database table, ensuring only one instance runs the job at a time. This reduced rate limits, improved reliability, and optimized costs. Check out https://ilovedotnet.org/blogs/using-a-distributed-lock-in-hosted-service-in-asp-net-webapi/ for more visuals and code samples.
