To get the size of a data type in .Net you can use or . I’ll briefly explain the difference between the two. 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 … Read more
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 … Read more
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 and can benefit from a better . I’m demonstrating this with example of how it severely decreased performance in my project. Adding IEquatable<T> has no side-effects, if … Read more
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 … Read more

Create folder structure In the root of your project (not wwwroot) create the folder structure for Areas manually. In this example I created an area named “Foobar”. Edit Startup.cs to … Read more
Doing game development I use a lot of timers. Every Update() I check if its time to do something. To make this as light as possible I made a small benchmark to check the speed of different ways of getting time. When running the code ignore the first 1000-result from each test (used for warmup). … Read more
I recently discovered how slow Console.MoveBufferArea actually is. I used it for writing NLog output to a console and discovered that at times of high output it became dead slow.
