Read OriginalThis detailed technical article explores the process of adding a new Intermediate Language (IL) instruction to the open-source .NET CoreCLR runtime. It walks through the steps required to implement a custom opcode, integrate it with the interpreter and JIT compiler, and enable runtime code generation via Reflection.Emit. The post provides background on CLR internals and IL's role, making it a deep dive for developers interested in runtime extensibility and low-level .NET mechanics.
