Hi everyone,
I followed all the steps in tutorial and it worked well. But I met a problem in tutorial 4, specifically in "Add the helper method to create the Google WebMercator coordinate system". When I added this method, the VS2012 showed red line under IProjectedCoordinateSystem that IProjectedCoordinateSystem is not in the namespace of ProjNet.CoordinateSystems. I don't know how to solve it.

BTW, I'm new to sharpmap and I wonder how I can learn it to draw maps in a website. Could you tell me an efficient way? Thx a lot!~

Add
using GeoAPI.CoordinateSystems;
