The following represents a draft upgrade path as .NET developers move to .NET 3.5.
It is amazing how things get som much better as we move forward!
--system and/or platform requirements for .Net 3.5 for developers

Developers would require a version of Visual Studio 2008 Professional or higher

--system and/or platform requirements for .Net 3.5 for application users

Users would require the .NET 3.5 framework installed on their machines (RTI websites would need to have the .NET 3.5 framework installed as well)

--compatibility issues

Visual Studio 2008 is 100% backward compatible with .NET 2.0 and provides a mechanism for you to target which version of the framework you wish to build with. I.e. you can still write 100% .NET 2.0 applications using Visual Studio 2008. All solutions that were created in Visual Studio 2005 would be 100% compatible in Visual Studio 2008.

--compelling new / better features of immediate use for applications (very brief -- no details)
