Run Time Inlining in C#?

c#, inline, performance

Solution

C# the language doesn't do inlining, but the .NET CLR JIT compiler can.

Virtuals might be inline-able in a sealed class, but I'm not sure about non-sealed classes. I would assume not.

JIT optimizes before the execution of the code, when a function is first called. Because before the JIT goes to work, you don't have any code to execute. :P JIT happens only once on the first call to a function, not on every call to the function.

Note also that inlining is only done within an assembly (DLL). The JIT compiler will not copy code from another assembly to inline it into the code of this assembly.
