Running multiple agents, one agent is creating unit test cases and the other is scaffolding out a new feature. Two different parts of the application, two different Git branches same repo. Normally would take two engineers and who knows how long. Now it takes one person and a day. The new feature will have unit test cases and end to end tests to go along with whatever new code get generated. The other agent is working on being test coverage up to as close 100% as possible

Day 33/100 Most .NET developers don’t know what happens after F5. And that’s exactly why they can’t debug the hard problems. Here’s what actually happens when you run a .NET application: 𝗦𝘁𝗲𝗽 𝟭: 𝗖𝗼𝗺𝗽𝗶𝗹𝗮𝘁𝗶𝗼𝗻 Your C# code doesn’t compile to machine code. It compiles to IL (Intermediate Language) via Roslyn. IL is platform independent, which is why the same .dll runs on Windows, Linux, and macOS. This is the part most people get right. 𝗦𝘁𝗲𝗽 𝟮: 𝗧𝗵𝗲 𝗥𝘂𝗻𝘁𝗶𝗺𝗲 (𝗖𝗼𝗿𝗲𝗖𝗟𝗥) CoreCLR loads your assembly and does three things: resolves all dependencies, loads types and metadata, and sets up the garbage collector. This is where most startup performance problems live, and most developers never look here. 𝗦𝘁𝗲𝗽 𝟯: 𝗝𝗜𝗧 𝗖𝗼𝗺𝗽𝗶𝗹𝗮𝘁𝗶𝗼𝗻 The JIT compiler converts IL to native machine code, method by method, on first call. That’s why the first request to your API is always slower. Tiered compilation helps: Tier 0 compiles fast, then Tier 1 re-compiles hot methods with full optimizations. Dynamic PGO takes it further by using actual runtime data to optimize. The alternative is NativeAOT, which compiles everything upfront at build time. No JIT, no startup penalty, smaller binaries. Tradeoff: no dynamic code generation. 𝗦𝘁𝗲𝗽 𝟰: 𝗘𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 Your native code runs on the CPU while the GC and Thread Pool work alongside it the entire time: The GC manages memory in three generations. Gen0 collects short-lived objects (most die here). Gen1 is a buffer. Gen2 holds long-lived objects and is expensive to collect. If your app has Gen2 collection spikes, that’s where your latency problems come from. The Thread Pool manages all your async work. Every time you await something, the Thread Pool decides which thread picks it up next. 𝗪𝗵𝘆 𝘁𝗵𝗶𝘀 𝗺𝗮𝘁𝘁𝗲𝗿𝘀 Understanding this pipeline is the difference between guessing why your app is slow and knowing exactly where to look. Startup slow? Check JIT and assembly loading. Random latency spikes? Check GC Gen2 collections. High memory? Check object lifetimes.

🚀 Types of Constructors in C# Every .NET Developer Should Know Constructors are one of the most fundamental concepts in Object-Oriented Programming. They help initialize objects and ensure your classes start with the right state. In C#, there are 5 main types of constructors every developer should understand: 🔹 1. Default (Parameterless) Constructor Automatically created by the compiler if no constructor is defined. It initializes variables with default values. 🔹 2. User Defined Default Constructor A parameterless constructor written by the developer to initialize objects with custom logic. 🔹 3. Parameterized Constructor Allows passing values during object creation so each object can have different data. 🔹 4. Copy Constructor Creates a new object by copying values from an existing object. 🔹 5. Static Constructor Used to initialize static members of a class. It runs only once before the class is used. 💡 Understanding constructors helps you write cleaner, more maintainable, and scalable C# applications. 📌 If you're learning .NET / C#, save this post for reference. #dotnet #csharp #softwareengineering #programming #dotnetdeveloper #coding #developers
