A couple of days ago, I found this nice post giving a poster that show the new stuff in the next major version of the .Net framework:

The poster is available in PDF and in Deep Zoom format (pretty cool !).

So, to be consice, .Net 4.0 is:

• a one more step to get Silverlight and WPF closer (Visual State Manager support in WPF)
• new WPF controls (ribbon, datagrid, calendar, datepicker…)
• new input extension to handle touch screen device
• parallel extension (ParallelEnumerable in System.Linq)
• new XAML functionality
• new stuff in Workflow, Data and Web systems (I don’t know them enough to give details).
