Parallel Extensions is a .NET Library that
supports declarative and imperative data
parallelism, imperative task parallelism,
and a set of data structures that make
coordination easier.
Parallel LINQ (PLINQ)
Task Parallel Library (TPL)
Coordination Data Structures (CDS)
Parallel Extension June 2008 CTP
Client Profile
Windows Presentation Foundation
Business focused controls
DataGrid, DatePicker, VSM
 Today part of the WPF Toolkit (update in March 09)
 http://www.codeplex.com/wpf
After .NET 4.0  More controls (Chart controls, …)
Silverlight Synergy (DeepZoom control ?)
Win7 Advances
Multitouch
 Windows API CodePack for .NET
(http://windowsapicodepack.codeplex.com)
ASP.NET MVC
Separation of Concerns, Testability
High control over market up
ASP.NET Dynamic Data support for MVC
Easily Create Custom controls and views
based on data base
ASP.NET better CSS and ID
ASP.NET AJAX
Javascript UI Templates and Databinding
AJAX Control Toolkit Enhancements
Client-side controls
Addition of JQuery
Messaging enhancements
Protocols - SOAP over UDP, WS-Discovery, WS-BusinessActivity,
WS-I BP 1.2
Duplex durable messaging
RESTful enhancements
Simplifying the building of REST Singleton & Collection Services,
ATOM Feed and Publishing Protocol Services, and HTTP Plain
XML Services using WCF
 WCF REST Starter Kit released on Codeplex to get early
feedback
Correlation enhancements
Content and context driven, One-way support
Seemless integration with Workflow
Services
XAML-only workflows are the new default
Unified model between WF, WCF, and WPF
Extended base activity library
More activities will be present on CodePlex
WF 4.0 simplifies data flow by adding:
Arguments, variables, and expressions
Significant improvements in performance
and scalability
New FlowChart Workflow
Improved WF 4.0 designer / Designer
Rehosting
There is great potential in WF + WCF
.NET 3.0 didn't provide any integration
.NET 3.5 added initial WCF support
.NET 4.0 is investing heavily in this area
 Workflow Services !!!
Think "WCF on the outside, WF on the
inside"
WCF exposes external interface
WF describes internal flow & state transitions
IIS 7/WAS is today’s hosting environment
for WCF service and WF workflows
(WorkflowServiceHost class)
Provides valuable hosting and management
features for your WCF and WF applications
Part of the Windows Server Application
Server role
Extensions built on top of IIS 7 with tracing,
monitoring and diagnostic capabilities
