.NET represents a new and improved way of developing software for the Windows platform. Given the chance, youd probably rewrite all of your existing code in the newer managed code environment that .NET provides. But it is difficult or impossible to throw out all existing legacy code and start over when a new technology arrives. Instead, you need to find a way to move forward with new .NET development while reusing existing pieces of tested, working code. You need a way to interoperate with the existing code until you have a chance to finally rewrite all of it in .NET.

The only recipe-style book on the subject,,"NET 2.0 Interoperability Recipes: A Problem-Solution Approach" guides Windows developers who are transitioning from native Windows code to .NET managed code. The book Explains new interop features in .NET 2.0 and VS .NET 2005 Covers PInvoke, COM, and COM+ (other books dont cover all three areas) Features most of its example code in C# and VB .NET, and also includes some managed C++/CLI Is written by a working developer with first-hand experience

.NET tools will allow you to interoperate with existing code. But finding the appropriate tool for the task at hand can sometimes be a frustrating experience. So this book will guide you past myriad infrequently used interop options to focus on those youll use most often.

It is difficult to just throw out all existing code and start over when a new technology arrives. That's the situation with Microsoft .NET, which represents a new and improved way of developing software for the Windows platform. Wouldn't you would love to rewrite all of your existing code in the newer managed code environment that .NET provides? However, you have that little problem known as legacy code. Fortunately, Microsoft .NET provides a rich set of tools interoperation with existing code. This book is written as a guide for Windows developers transitioning from native Windows code to .NET managed code.

Windows Workflow Foundation (WF) is a revolutionary part of the .NET 4 Framework that allows you to orchestrate human and system interactions as a series of workflows that can be easily mapped, analyzed, adjusted, and implemented. As business problems become more complex, the need for workflow-based solutions has never been more evident. WF provides a simple and consistent way to model and implement complex problems. As a developer, you focus on developing the business logic for individual workflow tasks. The runtime handles the execution of those tasks after they have been composed into a workflow.

Pro WF: Windows Workflow in .NET 4 provides you with the skills you need to incorporate WF in your applications, using a lively tutorial style with each example illustrated in C#. This book gets you up to speed with WF 4 quickly and comprehensively. Learn about WF 4's new designer, it's updated programming paradigm, and the completely new set of activities that can enable and extend your workflows. This book also includes detailed coverage of how to customize your workflows and access them in a variety of ways and situations so you can maximize the advantages of this technology. What you'll learn WF 4 basics New activities and changes to existing activities in WF 4 Customizing your workflows Accessing your workflows in a variety of ways in a variety of situations Using WF with Web Services and ASP.NET Integrating WCF and WF Who this book is for

This book is for intermediate to advanced .NET developers who need to learn how to use the latest version of Windows Workflow Foundation (WF 4). This book is not a primer on .NET or the C# language. To get the most out of the examples presented in this book, it is necessary to have a good working knowledge of .NET 2.0 or higher. All of the examples are presented in C#.

Windows Workflow Foundation is a groundbreaking addition to the core of the .NET Framework that allows you to orchestrate human and system interactions as a series of workflows that can be easily mapped, analyzed, adjusted, and implemented. As business problems become more complex, the need for a workflow-based solution has never been more evident. WF provides a simple and consistent way to model and implement complex solutions. As a developer, you focus on developing the business logic for individual workflow tasks. The runtime handles the execution of those tasks after they have been composed into a workflow. Pro WF: Windows Workflow in .NET 3.5 provides you with the skills you need to incorporate WF into your applications. This book gets you up to speed with Windows Workflow Foundation quickly and comprehensively. The practical aspects of using WF are covered in a lively tutorial style with each workflow concept illustrated in C#. You'll find detailed coverage of how to customize your workflows and access them in a variety of ways and situations so you can maximize the advantages of this technology. Pro WF: Windows Workflow in .NET 3.5 is written by an experienced Windows and .NET developer. Rather than simply duplicating the available references on the subject, author Bruce Bukovics leads you through a series of practical WF topics that enable you to gain immediate experience and learn how to use the technology as you progress through the book.

Windows Workflow Foundation is part of a bundle of new products that update .NET 2.0 into .NET 3.0. This book is one of the first to cover this important addition to .NET, and aims to provide the reader with a solid grounding in how workflows are implemented, executed, maintained and customized. By comprehensively covering WF from setup through implementation to customization readers are given a 'one stop' grounding in the subject. Given the importance of this technology release, the fact that WF is a free add-on, and the book's broad appeal, it will be useful to almost all existing or migrating .NET 2.0 developers.
