Improving String Handling Performance in .NET 7
Joydip Kanjilal
(Webinar is updated for .NET 7.) A string is an immutable type, which means that once you have created a string object, you cannot change it in any way. When you change or modify a string object, a new instance is created. There are several ways to overcome this performance issue. This session talks about how strings are represented in the CLR memory, the performance challenges you would often encounter when working with strings and how to fix them in C#.
