Benchmarking dynamic method invocation in .Net

Benchmarking method execution through interface, base class, virtual, override, dynamic, reflection and expression trees. In .Net there are many ways to execute a method. The fastest being the straight forward call to a static method. But how does its speed compare to other methods? There are countless reasons why we sometimes can’t just make a direct call. We… Read More »

Code sharing between VS and Unity 3D

In my previous blog post I covered how I usually set up new .Net projects. The post covered both naming convention, .Net Standard and .Net Core. In this post I will show a four ways you can share code between .Net projects and Unity 3D projects. There are several good reasons why you would like to do this.… Read More »

Setting up new .Net projects

Intro I have been a developer for somewhere around 30 years now. In my time I have created a few thousand projects of varying sizes, and for every new iteration I try to improve slightly on my previous. I also see a lot of code from others, and most what I see don’t seem care much about project… Read More »

sizeof() vs Marshal.SizeOf()

To get the size of a data type in .Net you can use sizeof()  or Marshal.SizeOf() . I’ll briefly explain the difference between the two. sizeof() sizeof()  (MSDN) can only be used on data types that have a known size at compile-time. It is compiled as a constant. If you attempt to use it on invalid data types you… Read More »

Cost of method wrapper

Introduction What happens if a method is just a wrapper for another method? Is the extra jump optimized away by compiler? Does it take much time? I thought I’d look into this and measure a bit. With the different compilers, Jits and runtimes I thought it would be fun to see what happens. I’ll use a == operator… Read More »

Speeding up Unitys Vector in lists/dictionaries

Introduction With this post I am digging into some performance improvements for Unity 3D’s Vector2, Vector3, Vector4 and Quaternion. The short version is that they really need IEquatable<T>  and can benefit from a better GetHashCode() . I’m demonstrating this with example of how it severely decreased performance in my project. Adding IEquatable<T> has no side-effects, if is actually best… Read More »

Simple app.config appSettings deserializer (with tree structure)

There are many ways to read configuraiton files in .Net. Using ConfigurationManager you can easily read for example appSettings section. But usually I want this to be in managed code. The solution often suggested is to create separate sections with a varying degree of manual work, field mapping and xml readers. Many of the solutions also suggest that… Read More »
