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
{ } New HTML Designer
![Page 6: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/6.jpg)
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
{ } CSS Manager
![Page 7: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/7.jpg)
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
{ } ASP.NET Support for LINQ
![Page 8: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/8.jpg)
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
{ } JavaScript Debugging and IntelliSense
The Challenge
The Solution

{ } Integrated ASP.NET AJAX
Visual Studio 2008 integrates and enhances ASP.NET AJAX:
Adding UpdatePanels and ScriptManagers to an existing ASP.NET application can dramatically decrease the number of post backs
All of the ASP.NET AJAX 1.0 controls and functionality are part of the tool box
ASP.NET AJAX Script Control Library available as a free download from CodePlex
The following new Project Items have been added:
AJAX Master Page
AJAX Client Library
AJAX Web Form
AJAX Client Control
AJAX Client Behavior Control
AJAX enabled WCF Service
The Solution

{ } ASP.NET AJAX Control Toolkit
Add common features to AJAX applications with no code required
Free open source download from CodePlex
Sample site is available for viewing
Lots of tutorials, samples, documents and forums available
Write your own Extenders!

{ } Microsoft Silverlight and Deep Zoom
My customers are demanding more from my web UIs - how to I take advantage of high-definition video and rich interactive applications in ASP.NET?
Microsoft Silverlight provides a cross-browser, cross-platform, cross-device framework for building rich interactive applications on the web
Supports high-definition video via the VC-1 codec
Tooling support in Visual Studio 2008 and Expression Studio create a rich design and development experience
Silverlight Hosting offers high-bandwidth, high-quality streaming at low cost
DeepZoom provides the ability to smoothly present and navigate large amounts of visual information (images) regardless of the size of the data, and optimizing the bandwidth available to download it.
The Challenge
The Solution

Expression Blend and Visual Studio 2008 work better together
Based on a common language – XAML
Tooling supports editing of artifacts from within both environments
{ } Designer / Developer Workflow
Getting information from designers to developers is a manual, painful process
The Challenge
The Solution
![Page 15: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/15.jpg)

{ } Web and Unit Testing improvements
AJAX-enabled web applications are very popular, but their asynchronous nature makes testing them very difficult
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
Disable Deployment
Test Inheritance
Directly go to the Point of Failure
Visual Studio 2008 Team System enables captures HTTP requests whether
user or script generated
The Challenge
The Solution

{ } JavaScript localization
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
![Page 18: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/18.jpg)
{ } Integrated code metrics
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
![Page 19: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/19.jpg)

{ } Enhanced code analysis
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
![Page 21: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/21.jpg)
{ } Performance profiler
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
New ability to visually compare performance data
The Challenge
The Solution
![Page 22: Chris Koenig - Krakow CodeCamp Slides](https://reader034.fdocuments.net/reader034/viewer/2022051818/54bd45654a7959a8338b45dc/html5/thumbnails/22.jpg)
Dynamically control
how performance
data is gathered.
Insert ‘marks’
which help you
correlate data
Compare 2
performance
reports against
each other
