Replaces the body of the specified function in the specified module.
HRESULT SetILFunctionBody( [in] ModuleID moduleId, [in] mdMethodDef methodid, [in] LPCBYTE pbNewILMethodHeader);
The SetILFunctionBody method replaces the relative virtual address of the function in the metadata so that it points to the new function body, and adjusts any internal data structures as required.
The SetILFunctionBody method can be called on only those functions that have never been compiled by a just-in-time (JIT) compiler.
Use the ICorProfilerInfo::GetILFunctionBodyAllocator method to allocate space for the new method to ensure that the buffer is compatible.
