Question

I want to tailor IET for my application. After checked the IET folder there is no introduction for customization on IET.
For example ,which version of  visual studio for open the "WaterUtilitiesNetworkEditingTemplate.sln". In the "WaterUtilitiesDesktopFunctions" I found there "LGSharedFunctions" reference is missing(see picture below). [ATTACH=CONFIG]13540[/ATTACH]
  Is there any basic user guide for the application source code introduction?

Add the source code to the most recent beta and included a VS 2008 SLN file.  If you ever need to open 2010 SLN in 2008, just open it in notepad and replace 11.00 with 10.00.  This only works if projects reference .net 3.5 and lower.

There is no help for customizing the source code.  The apps are made up a series of projects.  You should open the WaterUtilitiesNetworkEditingTemplate.sln file.

I have Visual Studio 2008 but it can not open "WaterUtilitiesNetworkEditingTemplate.sln ". This needs visual studio 2010 to open it?
