Just a quick question on Enterprise Library April 2007. If 3.0 is installed, it will install all the necessary projects for 3.0? Is there a way that I can check it?

Have you started working on .NET 3.5??

Is there anything available for download.

3.0 is basically for workflows, right?

.NET 3.0 is actually .NET 2.0 with some extensions added to it. As far as the Base Class Library, there's no difference between the two.

Will this still be the case with .NET 3.5? Where can I found out what new features they are planning to add with .NET 3.5?

• .NET 2.0 core (CLR)
  
• The 3.0 extensions (WCF, WPF, WF, CardSpaces)
  
• Language Integrated Query (LINQ) and data awareness
  
• ASP.NET AJAX
  
• New web protocol support for building WCF services including AJAX, JSON, REST, POX, RSS, ATOM and several new WS-* standards
  
• Full tooling support for WF, WCF and WPF including the new workflow-enabled services technology
  
• New classes in the base class library (BCL) for the .NET Framework 3.5 address the most common customer requests.
