How does the 'fixed' keyword work?

This technical article provides a deep dive into the 'fixed' keyword in C#. It explains how 'fixed' enables unsafe code by pinning objects in memory to prevent the garbage collector from moving them. The post details the collaboration between the compiler, JITter, CLR, and Garbage Collector, using code examples and IL inspection to show how 'fixed' works under the hood, including compiler optimizations and the ECMA specification for 'pinned' locals.
