What does MethodImplOptions.Synchronized do?

Question

Is the code below

[MethodImpl(MethodImplOptions.Synchronized)]
public void Method()

   MethodImpl();
}

same as

{
   lock(this)
    {
       MethodImpl();
    }
}

Answer 1

This was answered by Mr. Jon Skeet on another site.

Quote from Post

It's the equivalent to putting lock(this) round the whole method call.

The post has more example code.

Yes it is. See MethodImplOptions Enumeration
