GetHashCode.cs

public class MyValueObject:ValueObject<MyValueObject>
{
public int field1{get;}
public double field2{get;}
public string field3{get;}

public override int GetHashCode()
{
//don't forget to check fields for null
    unchecked 
    {
        int hash = (int) 2166136261;
        hash = (hash * 16777619) ^ field1.GetHashCode();
        hash = (hash * 16777619) ^ field2.GetHashCode();
        hash = (hash * 16777619) ^ field3.GetHashCode();
        return hash;
    }
}
