example Singleton implementation using Lazy object

SingletonPattern.md

how best to create singleton class

It is simplest, thread-safe solution with lazy initialization, that everyone can understand.

Example pull from here https://rubikscode.net/2017/06/11/different-ways-to-implement-singleton-in-net-and-make-people-hate-you-along-the-way/ But also see this Jon Skeets http://csharpindepth.com/Articles/General/Singleton.aspx#lazy

• don't do if null check
• don't use locks
• use lazy and static class / static constructor

namespace SingletonExamples
{
    /// <summary>
    /// Solution using Lazy implementation.
    /// </summary>
    public class SingletonLazy
    {
        private static readonly Lazy<SingletonLazy> instance =
        new Lazy<SingletonLazy>(() => new SingletonLazy());

        public static SingletonLazy Instance { get { return instance.Value; } }

        private SingletonLazy()
        {
        }
    }
}
