Hands-On W*F .NET 3.0: WCF, WF and WPF
|
|
|
|
|
In November 2006, Microsoft released .NET 3.0 (formerly known as WinFX), which includes 3 principal facets:
Capable of running on WinXP, WinServer 2003, and Windows Vista, .NET 3.0 provides a wealth of new services for creating:
- More powerful service endpoints that supplant .NET Remoting and .NET Web Services (.ASMX), address transactions and security, and do so with a single, unified programming model.
- Create WorkFlow applications that can run continuously and survive system resets.
- Rich presentation layers using 2D and 3D graphics with a single API.
Our HANDS-ON W*F .NET 3.0 Workshop addresses all 3 topics over 5 days.

You must have at least 1 year of experience programming the .NET Framework in C# or VB.NET.
Experience with the following is preferred, but not required (you're welcome to join us without these, but there'll be no hand-holding on these points):
- C# 2.0 (specifically, Generics, Custom Iterators and Anonymous Methods)
- Building .NET Web Services
- Managing .NET .config files with XML
- Using the VS2005 IDE
All labs will be worked using C# 2.0. (If you've not used 2.0, or you're a VB.NET developer, you'll be able to follow the labs via the step-by-step, cookbook approaches we'll provide.)

Windows Communication Foundation (WCF)
|
|
|
|
|
Until now, .NET developers have had two key choices for implementing the services that expose business objects to clients:
- .NET Remoting
- .NET Web Services
Both of these come with advantages -- and disadvantages.
.NET Remoting allows more runtime flexibility, can service binary protocols (TCP), offers high-fidelity to .NET runtime types, and is relatively performant. But Remoting will only service .NET-to-.NET communications, offers no built-in security or transaction model, and -- while easy to use for simple scenarios -- is relatively complex to implement when full-featured.
.NET Web Services (.ASMX) allow maximum platform independence, and are relatively simple to implement. But the .ASMX model only services HTTP/SOAP endpoints, offers little fidelity to .NET runtime types, and -- like Remoting -- offers little in the way of built-in security or transaction support.
To add to this: some applications may require that you implement service endpoints with both the Remoting and .ASMX models -- and if you do, you'll have to do so using distinctly different programming models and techniques.
The Windows Communication Foundation (WCF) is designed to address these issues directly. Through a single, unified programming model it offers:
- The flexibility to create different types of endpoints at runtime.
- The ability to service both binary and soap-based protocols.
- Services that can be consumed by both .NET and non-.NET clients.
- A built-in security model.
- Built-in transaction support.
- High-fidelity to .NET runtime data types.
Plus, WCF offers:
- Serialization facilities
- Queued exchanges
- Integration with MSMQ, COM+, ASP.NET Web Services, and even Microsoft's Web Services Enhancements (WSE).
In this course, you'll learn how to create WCF services that take advantage of these features.

Windows Workflow Foundation (WF)
|
|
|
|
|
Workflow applications have unique constraints:
- They often have to wait days, weeks, or months for events to occur, or for other activities to finish.
- They shouldn't consume processor cycles while waiting.
- They must survive machine resets.
- They often require asynchronous control flow.
- They often require the use of a compensation model, instead of traditional database transactions.
Meeting these requirements force developers to build a complex workflow infrastructure into their applications.
Windows Workflow Foundation (WF), provides a workflow infrastructure. With this WF-supplied runtime engine and a framework for implementing workflow, you can focus on the business logic, rules, and policies that you understand, rather than building workflow infrastructure plumbing.
In the WF portion of our course, you'll write several applications that will demonstrate how to build a range of workflow applications.

Windows Presentation Foundation (WPF)
|
|
|
|
|
Windows Presentation Foundation (WPF) is a rich set of services for the Windows graphics environment, that gives you a single API for manipulating virtually every graphic surface needed in a Windows application. (E.g., the same API lets you create both 2D and 3D graphics.) Prior to WPF, you'd need to work with GDI+ and DirectX as separate entities; with WPF you can combine both in the same application, using Visual Studio (or another Microsoft editor), and both can be addressed with the same programming language.
WPF lets you create and manipulate a variety of graphics entities, such as:
- Animation
- Fonts
- Printing
- Document Layout and formatting
- 2D Graphics
- 3D Graphics
- Video
In this section of the course, you'll how to use WPF to create rich presentation layers in your .NET3.0 applications.
