.NET structs never have reference equality

.NET structs never have reference equality, because structs are value types. Here is a fiddle https://dotnetfiddle.net/AvazwY

public class Program  
{
    public static void Main()
    { 
        var foo = new Foo();
        var bar = new Bar();

        Console.WriteLine(object.ReferenceEquals(foo, foo)); // false
        Console.WriteLine(object.ReferenceEquals(bar, bar)); // true
    }

    public struct Foo
    {
    }

    public class Bar
    {
    }   
}
