Hey, so I have the following IL:

il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Ret);

Which works fine. It basically returns the argument given. This, however:

il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Stloc_0);
il.Emit(OpCodes.Ldloc_0);
il.Emit(OpCodes.Ret);

Does not work. It crashes with the exception "Operation could destabilize the runtime.". Now, I know that the purpose of that is useless but I'm trying to reach my goal by small steps. Why does that not work?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
