Just a side note Mike for clarification on your comment. You may already realize this. A static object does not constitute a singleton. An instance object can be kept to a single instance through the use of a singleton pattern. An object is referenced through a property and if the instance already exists the existing instance is passed back instead of creating another instance of the object. Here is an example in my EventLogger class. I use it because I want the same event log throughout the application. Notice the constructor is protected so it cannot be constructed directly.

public class EventLogger
{
	#region Private Singleton

	private static EventLogger instance = null;
	private static EventLogger Instance
	{
		get
		{
			if(instance == null)
				instance = new EventLogger();

			return instance;
		}
	}

	protected EventLogger()
	{
	}

	#endregion Private Singleton
       // All other stuff stripped out.
}
