WPF blends together application user interface, documents, and media content, while exploiting the full power of your computer. WPF functionality extends support for Tablet PCs and other forms of input device, and provides a more modern imaging and printing pipeline. One of the most detailed books on WPF technology, it provides you with the no-nonsense, practical advice you need in order to build high-quality WPF applications quickly and easily.
It also digs into the more advance aspects of WPF and how they relate to the other elements of the WinFX stack and the. NET Framework 2. There are no reviews yet. At the core of any WPF application there is an Application object. Chapter 3 teaches you how to program the Application object, how to handle some of its events and how to create single instance applications.
Though not directly connected the topic of multithreading is also covered in this chapter. In traditional Windows development laying out controls on a form was a plain task. Just drag and drop the controls and place them at desired coordinates. This way of arranging controls is not necessarily the best way possible.
In fact WPF comes with many ways of laying out the controls. WPF opens many possibilities of using otherwise ordinary controls. Content controls allow you to place controls inside other controls e. Chapter 5 covers these techniques. Chapter 7 and 8 deal with classic controls such as buttons, textboxes and labeld and windowing abilities of WPF. When internet was relatively new developers wanted features of desktop applications on the web.
Now that internet is so popular the reverse is also true. That's why WPF provides a page based applications and navigation. Chapter 9 tells you how to go about developing page driven and browser hosted applications. Finally Windows applications have something similar to CSS.
The new WPF Styles allow you to apply a look and feel to a group of controls. Styles is the topic of Chapter If you like to jazz your applications with graphics then Chapter 13 and 14 are for you. They cover topics such as shapes, transforms, brushes, images, 2-D drawing and so on. Want more? Advanced embedding details, examples, and help! Introducing WPF -- Ch. XAML -- Ch.

First we'll explain the steps necessary to port apps in general, and then we'll walk through the specific changes that apply to the Bean Trader sample. The Desktop Guide documentation for. NET 6 and. NET 5 including.
NET Upgrade Assistant is a command-line tool that can be run on different kinds of. NET Framework apps. It's designed to assist with upgrading. NET Framework apps to. NET 5. After running the tool, in most cases the app will require additional effort to complete the migration.
The tool includes the installation of analyzers that can assist with completing the migration. For more information, see Upgrade a Windows Forms App to. NET 5 with the. NET Upgrade Assistant. This article references the Bean Trader sample app because it uses a variety of dependencies similar to those that real-world WPF apps might have. The app isn't large, but is meant to be a step up from 'Hello World' in terms of complexity.
The app demonstrates some issues users may encounter while porting real apps. The app communicates with a WCF service, so for it to run properly, you'll also need to run the BeanTraderServer project available in the same GitHub repository and make sure the BeanTraderClient configuration points to the correct endpoint. Keep in mind that this sample app is meant to demonstrate. NET Core porting challenges and solutions. It's not meant to demonstrate WPF best practices. In fact, it deliberately includes some anti-patterns to make sure you come across at least a couple of interesting challenges while porting.
The primary challenge of migrating a. NET Framework app to. NET Core is that its dependencies may work differently or not at all. Migration is much easier than it used to be; many NuGet packages now target.
NET Standard. Starting with. NET Core 2. NET Framework and. NET Core surface areas have become similar. Even so, some differences both in support from NuGet packages and in available. The first step in migrating is to review the app's dependencies and make sure references are in a format that's easily migrated to. NET Core. The first step to migrating a. Visual Studio makes this simple. Just right-click the project's packages. A dialog appears showing calculated top-level NuGet dependencies and asking which other NuGet packages should be promoted to top-level.
None of these other packages need to be top-level for the Bean Trader sample, so you can uncheck all of those boxes. Then, click Ok and the packages. Instead, they're stored globally as an optimization. Don't worry; since you still have the NuGet package references, the analyzers will be included in the project.
You just need to clean up the old packages. Now that you can see the top-level NuGet packages that the project depends on, you can review whether those packages are available on. You can determine whether a package supports. NET Core by looking at its dependencies on nuget. The community-created fuget. When targeting. NET Core or. NET Standard should work since. NET Core implements the. NET Standard surface area.
In some cases, the specific version of a package that's used won't target. NET Standard, but newer versions will. In this case, you should consider upgrading to the latest version of the package. You can use packages targeting. NET Framework, as well, but that introduces some risk. NET Core to. NET Framework dependencies are allowed because. NET Core and. NET Framework surface areas are similar enough that such dependencies often work.
However, if the package tries to use a. NET Core, you'll encounter a runtime exception. Because of that, you should only reference. NET Framework packages when no other options are available and understand that doing so imposes a test burden. If there are packages referenced that don't target. NET Standard, you'll have to think about other alternatives:. Windsor, version 4. FxCopAnalyzers, version 2. AsyncEx, version 4.
This package doesn't target. NET Core, but the newer 5. This is common when migrating because many NuGet packages have added. NET Standard support recently, but older project versions will only target. NET Framework. If the version difference is only a minor version difference, it's often easy to upgrade to the newer version. Because this is a major version change, you need to be cautious upgrading since there could be breaking changes in the package.
There is a path forward, though, which is good.
