New features in the .NET Framework 4.5 Developer Preview


I was going through Microsoft MSDN website and found that .Net Framework 4.5 developer preview is available as BETA version. 

Following are some of the features available in .Net Framework 4.5:-


Web:

• Support for new HTML5 form types.
• Support for model binders in Web Forms. These let you bind data 
  controls directly to data-access methods, and automatically 
  convert user input to and from .NET Framework data types.
• Improved handling of client script through bundling and 
  minification for improved page performance.
• Support for reading and writing HTTP requests and responses 
  asynchronously.
• Support for asynchronous modules and handlers.


WPF:

• The new Ribbon control, which enables you to implement a ribbon 
  user interface that hosts a Quick Access Toolbar, Application 
  Menu, and tabs.
• The new INotifyDataErrorInfo, which supports synchronous and 
  asynchronous data validation.
• Improved performance when displaying large sets of grouped 
  data, and by accessing collections on non-UI threads.
• Repositioning of data as the values change (live shaping).
• Better integration between WPF and Win32 user interface 
  components.
• Ability to set the amount of time that should elapse between 
  property changes and data source updates.


WCF:

• Simplification of generated configuration files.
• Support for contract-first development.
• Ability to configure ASP.NET compatibility mode more easily.
• Changes in default transport property values to reduce the 
  likelihood that you will have to set them.
• Validation of WCF configuration files by Visual Studio as part 
  of the build process, so you can detect configuration errors 
  before you run your application.
• New HTTPS protocol mapping to make it easier to expose an 
  endpoint over HTTPS with Internet Information Services (IIS).
• Ability to generate metadata in a single WSDL document by 
  appending ?singleWSDL to the service URL.
• Support for configuring services in code.
• XML Editor tooltips.


The description of these added features are not provided on the website. After installation and usage of new beta version of VS 2011 will give a idea about these new features.
