PDC 2009 Day #2: Silverlight 4

November 18, 2009 at 4:05 pm · Filed under .NET, Attention, Miscellaneous, Web 2.0

Lots of great new stuff in today’s beta.  A few things that stand out:

  • Hosting HTML
  • Context menus
  • WCF and REST enhancements
  • Support for RIA Services
  • Drag & Drop
  • Running out of sandbox for trusted apps
  • Sharing components between .NET 4 and SL 4

Lot of other things too.  I’m excited to start using this.  Also a shout out to Tim Heuer – he has helped me on a few things before and I got a chance to meet him today.

Those of you following NewsGang will know why I am very excited about these Silverlight developments.

From PDC2009 Day 1: Entity Framework 4

November 17, 2009 at 6:41 pm · Filed under .NET, Grid Computing

Lots of improvements to EF for 4.0:

  • Model-first development.
  • Lazy loading through relationships (i.e., no longer have to call Load)
  • POCO (i.e., define your own data classes against a model).
  • POCO only (i.e., define the model fully in code).
  • Code Generation options using the new T4 facility of VS 2010.
  • Testability improvements through IObjectSet
  • Can override SaveChanges
  • Better disconnected workflow (both by writing a little code and a no-code option that uses a different code generator).
  • Much better SQL (more compact, more efficient)
  • Execute arbitrary SQL
  • Easier Stored Procedures
  • Functions (a little strange how this was implemented, but now they are available).
  • Foreign Keys in the entities (no more manual interpretation of the Reference!)
  • Better Binding for forms apps and WPF

Pandelis, what do you think?
