How do I set a method as a setter using Dnlib?
setm.IsSetter = true; // set the method as setter (using Mono.Cecil)
Mono.Cecil declaration on MethodDefinition:
public bool get_IsSetter()
{
    return this.GetSemantics((MethodSemanticsAttributes.None | MethodSemanticsAttributes.Setter));
}

Where are these on Dnlib?

Oho! After checking it seems dnlib automatically adds MethodSemantics table!

So problem is solved!
