using System;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

namespace WebGis
{
	public class Singleton
	{
		private IMapRender _mapRender;
		private static Singleton _uni = new Singleton();

		private Singleton()
		{
			TcpClientChannel client = new TcpClientChannel();
			ChannelServices.RegisterChannel(client);
			_mapRender = (IMapRender)Activator.GetObject(typeof(IMapRender), "tcp://localhost:8088/MapService");
		}

		static public Singleton Instance()
		{
			return _uni;
		}


		public IMapRender MapRender
		{
			get
