A comprehensive design patterns library

In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. In addition, design patterns allow developers to communicate using well-known, well understood names for software interactions.

A walkthrough of Durable Entities

Durable Entities are a special type of Azure Function that allow you to implement stateful objects in a serverless environment.

We’ll demonstrate their power with a real-life example in the last section.

10 Tiny Things in C# I Wish Were Different

In this blog post I look at a few things I wish were different in C# and .NET. I consider this an anti-post in the sense that I actually believe there is an unsound obsession in programming circles with counting code lines or characters as exemplified in my own blog post World’s Smallest C# Program (featuring N).

Working with System.Random and threads safely in .NET Core and .NET Framework

In this post I look at some of the ways you can misuse System.Random for generating random numbers, specifically around thread safety. I start by showing how to use the built-in thread-safe Random generator in .NET 6. I then step back to previous .NET Core implementations, before the thread-safe Random generator was added, and show how to add your own. Finally, we take one more step back to .NET Framework, and look at he issues that arise there.
