c# can you force a function to NOT be inlined?

Can I force a function to NEVER be inlined?

I want the call stack returned by:
System.Diagnostics.StackTrace callStack = new
System.Diagnostics.StackTrace();
to be such that:
System.Diagnostics.StackFrame frame = callStack.GetFrame(0);

is the function itself, NOT the function's caller (due to a release build making the function inlined into its caller)!

thanks!
