Singleton: create instance inside static constructor [duplicate]

This question already has an answer here:

• Using Static constructors to create a singleton in C# 3 answers

I was reading about Singleton design pattern when i come across this implementation:

public class Singleton
{
    private static Singleton Instance { get; private set; }

    private Singleton()
    {
    }

    static Singleton()
    {
        Instance = new Singleton();
    }
}

Is this singleton thread safe? What are pros and cons of such implementation?
