common Singleton Pattern implementation using Generic

I read this link content(Jon Skeet) and implement the singleton pattern in a class that can be used for any object that you want to be singleton. http://csharpindepth.com/Articles/General/Singleton.aspx[^] Generic implementation of Jon Skeet's is here:

    public class Singleton<T> where T : new()
    {
        private static readonly Lazy<T> lazy = new Lazy<T>(() => new T());

        Singleton()
        {
        }

        public static T Instance
        {
            get
            {
                return lazy.Value;
            }
        }
    }

For example, we have a service:

public class SampleService
{
    public List<MyItemType> GetItems()
    {
        var dataList = new List<MyItemType>();
        //do some works and fill dataList
        return dataList;
    }
}

Everywhere I want to use SampleService, I can get a singleton instance in this way:

var serviceInstance = Singleton<sampleservice>.Instance;

var myList = serviceInstance.GetItems();
