How To Write Very Fast C# Code
I presented this webinar in 2017 for Postsharp, a company that has developed a very cool toolkit that allows you to write aspect-based C# code.
In the webinar you’ll see several techniques to write very fast C# code. I will demo code to speed up exceptions, string handling, array manipulation, loops, structs, memory copying, and instantiating and accessing objects.
