Entity Framework 4

Aug.02, 2010 in C# Leave a Comment

Some of the big improvements in EF4 include:

  • POCO Support: You can now define entities without requiring base classes or data persistence attributes.
  • Lazy Loading Support: You can now load sub-objects of a model on demand instead of loading them up front.
  • N-Tier Support and Self-Tracking Entities: Handle scenarios where entities flow across tiers or stateless web calls.
  • Better SQL Generation and SPROC support: EF4 executes better SQL, and includes better integration with SPROCs
  • Automatic Pluralization Support: EF4 includes automatic pluralization support of tables (e.g. Categories->Category).
  • Improved Testability: EF4’s object context can now be more easily faked using interfaces.
  • Improved LINQ Operator Support: EF4 now offers full support for LINQ operators.

EF4 enables you to:

  • Develop without ever having to open a designer or define an XML mapping file
  • Define your model objects by simply writing “plain old classes” with no base classes required
  • Use a “convention over configuration” approach that enables database persistence without explicitly configuring anything
  • Optionally override the convention-based persistence and use a fluent code API to fully customize the persistence mapping

Silverlight 4 Tools for Visual Studio 2010 and WCF RIA Services is now available for download

May.19, 2010 in .Net Leave a Comment


Silverlight Tooling Support

Visual Studio 2010 includes rich tooling support for building Silverlight and WPF applications.

It includes a WYSIWYG designer surface that enables you to easily use controls to construct UI – including the ability to take advantage of layout containers, and apply styles and resources:

The VS 2010 designer enables you to leverage the rich data binding support within Silverlight and WPF, and easily wire-up bindings on controls.  The Data Sources window within Silverlight projects can be used to reference POCO objects (plain old CLR objects), WCF Services, WCF RIA Services client proxies or SharePoint Lists.


Silverlight 4 Tool Enhancements

Today’s Silverlight 4 Tooling Release for VS 2010 includes a bunch of nice new features.  These include:

Support for Silverlight Out of Browser Applications and Elevated Trust Applications

You can open up a Silverlight application’s project properties window and click the “Enable Running Application Out of Browser” checkbox to enable you to install an offline, out of browser, version of your Silverlight 4 application.  You can then customize a number of “out of browser” settings of your application within Visual Studio:

Notice above how you can now indicate that you want to run with elevated trust, with hardware graphics acceleration, as well as customize things like the Window style of the application (allowing you to build a nice polished window style for consumer applications).

Support for Implicit Styles and “Go to Value Definition” Support:

Silverlight 4 now allows you to define “implicit styles” for your applications.  This allows you to style controls by type (for example: have a default look for all buttons) and avoid you having to explicitly reference styles from each control. 

In addition to honoring implicit styles on the designer-surface, VS 2010 also now allows you to right click on any control (or on one of it properties) and choose the “Go to Value Definition…” context menu to jump to the XAML where the style is defined, and from there you can easily navigate onward to any referenced resources.  This makes it much easier to figure out questions like “why is my button red?”:
