I'll be posting a series of Live Templates I've created, as JetBrains has not yet created a community site where we can share and import directly from Visual Studio yet. (hint, hint).

Singleton

First a quick note.  The obvious way to implement singletons in c# is not thread safe:

public sealed class Singleton
{
    static Singleton instance=null;

    Singleton()
    {
    }

    public static Singleton Instance
    {
        get
        {
            if (instance==null)
            {
                instance = new Singleton();
            }
            return instance;
        }
    }
}

 For an excellent discussion on the topic, read Jon Skeet

I based my template on his solution 4:

public sealed class Singleton
{
    static readonly Singleton instance=new Singleton();

    // Explicit static constructor to tell C# compiler
    // not to mark type as beforefieldinit
    static Singleton()
    {
    }

    Singleton()
    {
    }

    public static Singleton Instance
    {
        get
        {
            return instance;
        }
    }
}

#region Singleton

private static readonly $ClassName$ _instance = new $ClassName$();

static $ClassName$(){}
private $ClassName$(){}

public static $ClassName$ Instance
{
    get { return _instance; }
}
