Hover over a using statement, choose the lightbulb icon, and then choose Remove Unnecessary Usings from the drop-down list.Ĭhoose whether you want to fix all occurrences in the Document, the Project, or the Solution. You can use Quick Actions to refactor, generate, or otherwise modify code with a single action.įor example, one useful task that you can perform by using Quick Actions is to Remove unnecessary usings from the C# code in the tab. We'll also highlight the unique-to-XAML features in the IDE, too. We'll touch on several of the universal IDE features that can help you develop your XAML code. It includes most of the features that you'll find in the IDE code editor. The middle pane is the "code" part of the XAML code editor. When you select from the list, your focus in the code editor will snap to the line of code that includes the property you selected. Specifically, it shows you a list of the properties in your code. The Member: Window on the right helps you view and navigate to attribute or child elements. When you select from the list, your focus in the code editor will snap to the line of code that includes the element you selected. Specifically, it shows you an outline-like view that reveals the tag structure of your code. The Element: Window on the left helps you view and navigate to sibling or parent elements. The Window dropdown lists have different functions, as follows: However, if you view the Tooltip for these UI elements, it further identifies them as the "Element: Window" and the "Member: Window". In the second row at the top of the XAML code window, there are two Window dropdown lists. (To restore the bottom pane, choose the same button again, which is now named the Expand Pane button.) The Collapse Pane button enables you to collapse what's in the bottom pane, whether that's the code editor or the Designer.The Horizontal Split button changes the location of the XAML Designer and the XAML code editor in the IDE from a vertical alignment to a horizontal alignment.The Vertical Split button changes the location of the XAML Designer and the XAML code editor in the IDE from a horizontal alignment to a vertical alignment.The Pop Out XAML button creates a separate XAML code editor window that's outside of the IDE.Ĭontinuing at the right, there's a Vertical Split button, a Horizontal Split button, and a Collapse Panes button.The XAML tab changes the focus back to the XAML code editor.The Swap Panes button reverses the location of the XAML Designer and the XAML code editor in the IDE. ![]() The Design tab changes the focus from the XAML code editor to the XAML Designer.In the first row at the top of the XAML code window, on the left, there's a Design tab, a Swap Panes button, a XAML tab, and a Pop Out XAML button. Next, let's take a look at the functions of each of the UI elements in the code editor. Here's a look at the XAML code editor window itself. While the code editor window for XAML apps shares some UI (user interface) elements that also appear in our standard IDE, it also includes a few unique features that make developing XAML apps easier. To continue, let's learn more about the XAML code editor. The Properties window, where you change the way your UI looks and how the UI controls work.The Solution Explorer window, where you manage your files, projects, and solutions.(You can also edit your code in real time while you're debugging with XAML Hot Reload.) The Debug button, where you run your code and debug it.The Toolbox dockable window, where you add controls to your UI.The XAML Designer window, where you design your UI.The XAML code editor window-the subject of this article-where you create and edit your code.The following image shows several of the key IDE tools you'll use along with the XAML code editor.įrom the bottom left of the image going clockwise, the key IDE tools are as follows: ![]() To start, let's take a look at the IDE (integrated development environment) with an open WPF project. This article outlines both the role the code editor plays when you develop XAML-based apps, and the features that are unique to the XAML code editor in Visual Studio 2019. The XAML code editor in the Visual Studio IDE includes all the tools you need to create WPF and UWP apps for the Windows platform, and for Xamarin.Forms.
