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

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.
