        _token = Guid.NewGuid();
    }

    public Guid Token
    {
        get { return _token; }

[TestClass]
public class UnitTest2
{
    [TestMethod]
    public void TestMethod1()
    {
        Console.WriteLine(Singleton.Instance.Token);
    }
}
[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        Console.WriteLine(Singleton.Instance.Token);
    }
}

During executing both tests output the same guid.
