Question

What will be the new features available in ASP.Net 4.0?

Answer 1

There are several videos on the Mircosoft 9 channel:

• ASP.NET 4.0 Roadmap by Scott Hunter
  It looks like someone took notes on the session in this conversation.
• New ASP.NET 4.0 features by Stephen Walter

---

Quoted (in part) from these session notes in a related blog post:

<b> Web Forms

• Developers can manage management identifiers that affect the displayed customer identifier.
• Remove bloat id and 'mangling'
• CSS:
  • Ideally remove the need to use CSS adapters
  • Defer CSS styles and get around existing style properties
    • non-inline style attributes
  • Support for HTML rendering without a table.
• URL routing for web forms
  • Friendly URL handling for web forms.
  • URL routing configuration model
• View status
  • Disable on page, enable certain controls - they will provide granular control of viewstate - today it’s back
  • Disable controls, enable child controls
  • GridView / ListView works better without viewstate
• ASP.NET Dynamic Data

Ajax

• Continue implementing ASP.NET Ajax: RIA
• Contact JavaScript Developers
• Provide page developer support
• jQuery including Intellisense
• Templates and data binding
  • Client-side, REST, or web service processing.
  • Covers for Developer Scripts and Developer Components
• DOM manipulation, selectors ...
• Higher Level Ajax Components
  • Ajax Control Toolkit is part of the strategy - they will make part of the toolkit of the entire ASP.NET package
  • New controls
• Centralized script libraries and decay for performance

<b> ASP.NET MVC

• Appeal to those who want to share problems, TDD, full control
• Ruby on Rails, Django, PHP
• Based on ASP.NET MVC 1.0
• ASP.NET MVC (Model View Controller)
• Asynchronous controllers
• Sub-controllers and views
• Declarative controls

<b> ASP.NET Kernel

• Specify the pain points in the client.
• Scale and performance improvements
• Cache extensibility and performance:
  • Enable caching like Velocity

Answer 2

There are many:

• static client identifiers
• improved dynamic data support
• better routing function support (made by popular ASP.NET MVC) for web form applications
• many Ajax improvements
