    • 3. Web development has evolved so that developers are expected to deliver rich user experiences
    • 4. { challenges } Are Everywhere…
    • 5.  
    • 6.

      Breakthrough User Experiences
    • 7.  
    • 8.
        • HTML is getting more and more complicated – we need help!
        • Visual Studio® 2008 provides a powerful new HTML designer that tames even the most complicated HTML; it includes
        • A split view that enables you to see your HTML from a source and design perspective at the same time
        • Nested master pages to help you factor your HTML more efficiently
      The Challenge The Solution
    • 9.  
    • 10.
        • Cascading Style Sheets (CSS) are ubiquitous because they promote accessibility and standards compliance
        • However, designer-generated CSS can be difficult/intimidating for developers to work with
        • New features for working with CSS style sheets
        • Intellisense for CSS
        • Filtered lists of which styles are being in a page or selection
        • Visually apply styles to elements
        • Even the most complicated, designer-created CSS styles are now simple to work with
      The Challenge The Solution
    • 11. CSS styles used in page Split view that shows both markup and design
    • 12. Intellisense that shows what CSS class names are available ‘ Go to definition’ option enables you to go to source of CSS style from markup
    • 13.
        • It’s always about data!
      The Challenge
        • Use LINQ directly in an ASP.NET page with LinqDatasource
        • Just another data source, so it works with any ASP.NET control
      The Solution
    • 14. { ASP.NET Support For LINQ }
    • 15.
        • Languages like JavaScript are more and more popular
        • Their type-less, dynamic nature presents challenges to traditional development activities like debugging and statement completion
        • Visual Studio 2008 makes JavaScript a 1st class development experience with
        • Syntax coloring
        • Intellisense
        • Debugging
      The Challenge The Solution
    • 16.  
    • 17.
        • HTTP is a stateless protocol, so web applications must post back to servers to update themselves
        • The user experience is degraded because the entire page must be re-drawn
        • An unnecessarily high load is put on the server because the entire page must be rendered again
        • Bandwidth is being wasted to send updates to elements that have not changed
      The Challenge
    • 18. UpdatePanel is the only change needed Core content stays the same – just located in UpdatePanel now
    • 19. image=/images/newimage.gif&page=4&items=show_sales GET /default.aspx HTTP/1.1 Host: www.fabrikam.com User-Agent: Internet Explorer/7.0
    • 20.
        • All my services are being re-written with WCF – how does my ASP.NET application call them?
        • Visual Studio 2008 provides a new project item that creates a default AJAX-enabled WCF service
        • Existing WCF services can be decorated with an attribute to convert their communication format to something that is AJAX friendly (i.e., JSON or REST)
        • Also, in Visual Studio 2008, the ScriptManager supports the registration of WCF services as well ASMX
      The Challenge The Solution
    • 21. New Project Item Attribute that makes this WCF service AJAX-callable
    • 22. { ASP.NET AJAX And Visual Studio 2008 }
    • 23.
        • My ‘breakthrough’ only works for Internet Explorer; but my customers use other browsers too
        • In Visual Studio 2008, ASP.NET AJAX provides client-script libraries that incorporate cross-browser ECMAScript (JavaScript) and dynamic HTML (DHTML) technologies; this technology is compatible with commonly used browsers such as
        • Internet Explorer
        • Mozilla Firefox
        • Apple Safari
      The Challenge The Solution
    • 24.
        • AJAX-enabled web applications are very popular, but their asynchronous nature makes testing them very difficult
        • Visual Studio 2008 Team System enables team members to target even the most complex AJAX applications – HTTP requests, whether user or script generated are captured as part of the web test
      The Challenge The Solution
    • 25.
        • Practicing formal Test Driven Development (TDD) is very demanding for even the most sophisticated of development tools
        • Visual Studio 2008 Team System makes great strides towards making TDD more productive. These improvements include
        • Better execution times
        • Run tests
        • Short cut keys to run tests
        • Disable deployment
        • Test inheritance
        • Directly go to the point of failure
      The Challenge The Solution
    • 26.
        • Less than 15% of the world uses English as their everyday language
        • Visual Studio 2008 and ASP.NET provide many different ways to ensure that your web application is ready for the world
        • The ScriptManager supports a setting that enables client script to format a JavaScript Date or Number object based on a culture value; this does not require a post back to the server
        • Localized resources can be included in a ScriptManager registered JavaScript file and used throughout your application
      The Challenge The Solution
    • 27. { Multi-Browser Support }
    • 28.
        • How do developers know they are writing code that can be maintained and understood in the future?
        • Visual Studio 2008 Team System integrates sophisticated code metrics that enable developers to clearly understand how maintainable and complex the code they are building is; This understanding is gathered from the following metrics
        • Cyclometic complexity
        • Maintainability index
        • Inheritance depth
        • Class coupling
        • Lines of code
      The Challenge The Solution
    • 29.  
    • 30.
        • Code reviews are time consuming, error prone and depends on ‘group’ knowledge
        • Code analysis examines every path code might take; looking for known problems and concerns; This feature has been greatly enhanced in Visual Studio 2008
        • Better discoverability of the feature through the Developer top-level menu
        • More flexible warning suppressions
        • Code analysis report comparison
        • Enhanced code analysis check-in policy
        • Code-aware spell checker
      The Challenge The Solution
    • 31.
        • Understanding data gathered by a profiler is difficult and tedious
        • In Visual Studio 2008 Team System, the industrial strength profiler has been enhanced across the board; this includes
        • New data collection control
        • WCF support
        • However, probably its most notable features is its ability to visually compare performance data
      The Challenge The Solution
    • 32. Dynamically control how performance data is gathered Insert ‘marks’ which help you correlate data Compare 2 performance reports against each other
    • 33.
        • Functional testing for ASP.NET AJAX and JavaScript
        • Integrated code metrics
        • Improved performance and scalability profiling
      Faster, easier development
        • A powerful, new HTML designer
        • CSS management
        • JavaScript debugging and Intellisense®
        • Better support for working with data
              • ListView control
              • LinqDataSource
      Less effort, more effect
        • ASP.NET AJAX built-in
        • Enhanced AJAX functionality
          • Better interoperability with WebParts, <asp:treeview>, <asp:menu>, etc
        • Nested master pages
