Dynamic Data App consists of three Components:
Data Model – LINQ to SQL mapping file
Page templates – ASPX pages that provide default views of data
Dynamic Data Fields – User Controls for rendering individual fields
Provides a view of the Data based on Default Templates
Templates use the data model to determine the correct controls to
display and their behavior
AJAX-enabled templates provide filtering, paging, and validation

The Challenge
AJAX-enabled web applications are very popular, but their
asynchronous nature makes testing them very difficult
The Solution
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 Entity Framework is a set of technologies that simplify
the development of flexible data-oriented applications.
Provides an intrinsic layer of abstraction over a database
called the Entity Data Model (EDM)
Developers code against conceptual entities representing the data
Conceptual entities are mapped to the database schema
Mapping is explicit and can be changed
Benefits:
Abstracts developers from the underlying database tables and
columns where the data is stored
Exposes data in the form of domain-specific object
Isolates and minimizes impact of changes between app and data
Decreases the amount of code and maintenance required
LINQ to Entities
Entity Data Model
Abstraction over a relational database
Consists of conceptual & logical models
Provides mapping layer between conceptual
model and logical model
Entity Client
Provides classes similar to ADO.NET
Providers
Can return results as DbDataReaders
Entity SQL
Textual SQL language for dynamic queries
Object Services
Enables you to work with object instances
Provides persistence and change tracking

ADO.NET Data Services provides the ability to create and
consume data-centric, RESTful services.
Expose data as a URI-addressable resources
i.e. http://host/NorthwindDataService.svc/Customers(492)/Orders
Services use URIs to locate and identify data
URIs can be used to traverse associations
Clients can filter, page, & sort data by specifying parameters on the URI
Apps can interact with the resources using HTTP verbs
GET, PUT, POST, or DELETE
Data can be represented in JSON or ATOM Publishing
Protocol (AtomPub) formats – as specified by the client
Simplifies data connectivity for AJAX and Silverlight apps

AJAX-enabled templates provide filtering, paging, and validation
The Challenge
All my services are being re-written with WCF – how does my
ASP.NET application call them?
The Solution
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
Microsoft's next-generation platform for distributed systems

The Challenge
How do developers know they are writing code that can be
maintained and understood in the future?
The Solution
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
Code reviews are time consuming, error prone and depends on
‘group’ knowledge
The Solution
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
Understanding data gathered by a profiler is difficult and
tedious
The Solution
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
Compare 2
