The latest changeset (20719) has the fix for MapImage_Wheel doesn't handle MouseEventArgs.Delta correctly and Null reference if no map loaded.

I also handle the MouseHover event in the MapImage control and set the focus to that control, so the mouse wheel works predictably. This was a problem for some users, such as jianyunli in MapImage didn't get MouseWheel event.

I have a problem compiling the Extensions assembly:

On PostGIS.cs line 195:

    if (!String.IsNullOrEmpty(_defintionQuery!=null))
      strSQL += this.DefinitionQuery + " AND ";

The code gives me the error: The best overloaded method match for 'string.IsNullOrEmpty(string)'.

Shouldn't the code be

    if (!String.IsNullOrEmpty(_defintionQuery))
      strSQL += this.DefinitionQuery + " AND ";

Yea, I noticed that too. I'm not sure what we are doing with that file - I think it is being deprecated in favor of the more current PostGIS2.cs provider. I'll mark it as a work item. Thanks for the heads up.
