Mastering C# Async Streams: IAsyncEnumerable<T> in Practice
Async streams let C# methods return sequences that are produced asynchronously. This guide explains how to declare, consume, and debug <code>IAsyncEnumerable<T></code>, covering common pitfalls and best practices.
C# Records as Immutable Domain Models and DTOs: An Architecture Note
C# records provide value equality and init-only properties that make them suitable for DTOs and domain models at trust boundaries. This architecture note covers the minimal design, validation patterns, shallow immutability limits, and when to switch to entity semantics.
Replacing Polling with Cosmos DB Change Feed: A Practical Migration Path
Replace inefficient polling with Cosmos DB's change feed: ordered per-partition events, automatic scaling via the Change Feed Processor, and a C# worked example. Key limitation: deletes require soft-delete or tombstone patterns.
azureMake Nullability Explicit in .NET with Nullable Reference Types
NullReferenceException remains common because reference types were nullable by default. Enabling nullable reference types in C# shifts null checks to compile time, with adoption patterns, a worked DTO example, and trade‑offs for .NET teams.

Extract an interface from a C# class in JetBrains Rider using Refactor This, then verify with dotnet build.
ReadOnlySpan<T> in Practice: Slicing Strings Without the Garbage
Substring() copies data to the heap. ReadOnlySpan<T> gives you a view into the original buffer instead. Here is how that changes parsing loops, where it stops working, and how to verify the difference.
Enable and Consume Azure Cosmos DB Change Feed for Event‑Driven Processing
Learn how to turn Cosmos DB into an event source by enabling the Change Feed, setting up a lease container, and using the Change Feed Processor Library in C#. The guide covers configuration, validation, monitoring, and fallback strategies for reliable event handling.
Slice Strings Without Allocating: ReadOnlySpan<T> in C#
Use ReadOnlySpan<char> to slice strings without heap allocations. Learn ref struct limits and a parsing example.
