Type of issue

Other (describe below)

Description

The article attributes the fact that ReferenceEquals=false to the fact that a structure was copied, however it's not true - it will always return false, even in both examples (in which clearly no copy is involved); so it shouldn't be attributed to the fact of copying, but rather due to boxing ;)

public struct A
{
}

public class Assertions
{
	internal static A A1 = new A();

	public void Y()
	{
		Console.WriteLine(object.ReferenceEquals(A1, A1));
		Lol(ref A1);
	}

	private void Lol(ref A a)
	{
		Console.WriteLine(object.ReferenceEquals(A1, a));
	}
}
