Example

This is compiled on Windows with target framework sets to 4.5.2, and ran with mono.

using MonoMod.Utils;

namespace ConsoleApp {
    public struct StructWithGetter {
        public int A => 1;

    }

    internal class Program {
        public static void Main(string[] args) {
            StructWithGetter obj = new StructWithGetter();
            DynamicData dynamicData = new DynamicData(obj);
        }
    }
}
