C# 10 (coming with .NET 6) aims to reduce file clutter. **Global Usings** allow you to define namespace imports once for the entire project. Manual Creation Create a file `GlobalUsings.cs`: Implicit Usings The SDK can do it for you based on project type. This automatically imports `System.Net.Http.Json`, `Microsoft.AspNetCore.Builder`, etc., in Web projects. Key Takeaways Reduces […]

Dapr v1.0 is production-ready. It solves the hardest parts of distributed systems: State management, Service Invocation, and Event-driven messaging. This guide implements the “Virtual Actor” pattern using Dapr actors. Virtual Actors Actors are single-threaded units of state and logic. Dapr handles their lifetime (activating them when a message arrives, deactivating them after timeout). Output Bindings […]

Reflection is slow. It happens at runtime, bypasses type safety, and prevents trimming. Source Generators solve this by generating code at compile time. In this guide, we build a generator that automatically implements a `MapTo` method for DTOs, replacing AutoMapper. The Goal The Generator Logic Key Takeaways Source Generators enable **Zero-Overhead abstractions**. They are essential […]

The Fan-Out/Fan-In pattern allows you to execute tasks in parallel and then aggregate the results. This is famously difficult in standard serverless, but trivial with Durable Functions. The Orchestrator How it Scales Key Takeaways The Orchestrator function replays from the start after every `await`. Avoid non-deterministic code (like `DateTime.Now`) inside the orchestrator logic. Activities run […]

You know Pods and Services. But to run K8s in production, you need to understand the Control Plane, Etcd consistency, and the Scheduler’s decision-making process. Control Plane Internals The Reconciliation Loop Kubernetes is basically a set of infinite loops checking `Current State == Desired State`. If not, it acts. Key Takeaways **Etcd** is the brain; […]
