Getting a PropertyInfo of a dynamic object

I have a library that is doing a bunch of reflection work relying on the PropertyInfo of the classes it receives (to get and set values).

Now I want to be able to work with dynamic objects, but I can't find how to get the PropertyInfo of a dynamic's properties. I've checked the alternatives, but for those I'd need to change everywhere I use PropertyInfo to get/set values.

public void Mapping(dynamic entity)
{
    // - Always null
    PropertyInfo p = entity.GetType().GetProperty("MyID");
    // - Always null
    PropertyInfo[] ps = entity.GetType().GetProperties();
}

Is it possible to get or create a PropertyInfo somehow just to be able to use it's GetValue() and SetValue() on a dynamic object?
