Visual Studio is all about developer productivity, and Visual Studio 2015 continues to make significant investments to help developers get more done in less time.
The code editor UI and editing experiences for C# and Visual Basic have been replaced with new experiences built on the .NET Compiler Platform ("Roslyn"). Many of the features you love today have been improved or revamped.
Light Bulbs are the home for all quick actions you take in the Visual Studio Editor, including fixes to common code issues and refactoring code. When you have issues in your code, a Light Bulb shows suggested fixes for those issues. All refactoring operations have been moved to the Light Bulb, which you can access any time by typing Ctrl +
Code refactoring: Introduce local:
Code refactoring: Inline temporary variable:
Refactoring support for Visual Basic has been added for the first time, and is accessible through the Light Bulb.
Renaming improvements: it highlights all the instances of the identifier you want to rename, letting you type the new name to all instances at once directly in the editor.
Live code analysis and automatic fixes as you type: includes with specific code-aware guidance for the Microsoft platforms and NuGet packages that you're targeting. At Preview, you need to add the live FxCop analyzers through a NuGet package you get from the NuGet Gallery, as you would any other package. As you pull in any given live rule, it displaces the equivalent post-build FxCop rule, so you don't get duplicate hits. Here is an example from the Code Analysis for Azure package.
Rewritten expression evaluator for C# and Visual Basic: Improvements include support for LINQ and lambda expressions in the Watch and Immediate Windows.
Custom Window Layouts: Save custom window layouts by clicking Save Window Layout from the Window menu, and apply a custom layout by clicking Apply Window Layout from the Window menu. You can also apply a layout by using the pre-assigned keyboard shortcuts. The first nine layouts also have keyboard shortcuts from Ctrl+Alt+1 to Ctrl+Alt+9. Other tasks you can perform include deleting, renaming, and reordering layouts by clicking Manage Window Layout from the Window menu.
XAML Designer: You can your Templates and Styles stored in external resource dictionaries within the context of your usage. This experience has been further refined to use Peek to enable a true in-situ resource editing in the XAML designer.
High-Resolution Icons: Visual Studio 2015 supports high resolution icons in command bars, tool window toolbars (standard), the main menus, error list, status bar, and some Solution Explorer project types when your device is running at greater than 100% DPI scaling. High-resolution icons are also supported for extensions.
Menu casing: Menus appear in Title Case style instead of ALL CAPS style.
Touch support: The Visual Studio editor supports scrolling (tapping-and-dragging on the editor surface on the regular and enhanced scrollbars), pinch-to-zoom, select a whole line by tapping in the editor margin, select words by double-tapping them, and press-and-hold to invoke the editor context menu.
The Configuration and Platform dropdown values for the Visual C++ Property Page dialog remember the last user selection when the property page is closed and reopened.
Send a Smile/Frown: offers better tools to report slowness, hangs, and crashes. You can attach files or tag your feedback, to better describe the issue as well. Furthermore, the Feedback icons and menu items have been updated to improve discoverability.
Add-ins are no longer supported in Visual Studio 2015; add-in project templates and the Add-in Manager have been removed. You should convert your add-ins to VSPackage extensions. For more information, see FAQ: Converting Add-ins to VSPackage Extensions.
Touch gestures in the Visual Studio editor give developers flexible input modalities, and are especially powerful with large touch screens in team collaboration environments. Gestures include scrolling, pinch-zoom, line selection, and press-and-hold to invoke context menus.
Add Connected Services makes it easy for developers to consume service APIs in their client and web applications including Microsoft Services such as Office 365 APIs, Azure Storage, and third-party services (through extensions).
Synchronized Settings (roaming settings) in Visual Studio 2015 improves upon the roaming features first introduced with Visual Studio 2013. It adds more settings and synchronizes across the Visual Studio product family including different SKUs and Blend. You can access your settings by typing "sync" in Quick Launch, or navigating to Tools > Options >Environment > Synchronized Settings.
Notification Hub UI is streamlined to make it easier to scan quickly. Additional kinds of notifications have been added including performance issues, rendering issues, and crashes, and you can now tell Visual Studio to stop showing a notification.
- Any un-flavored VB/C# projects (e.g. console apps, class libraries, Win form app)
- Windows Phone Silverlight 8.0/8.1 (VB/C#)
- WPF and PCL
You can add/remove references to shared projects via the Reference Manager, on the Shared Projects tab. The shared project reference shows up under the References node in the Solution Explorer, but the code and assets in the shared project are treated as if they were files linked into the main project.
- JSDoc comments: Documentation comments written in the JSDoc format are shown when using IntelliSense. (For more information about JSDoc comments, see http://usejsdoc.org.)
- ECMAScript 6 Features: includes classes, arrow functions, and template strings.
With a redesign of Blend, it is more than ever the preferred tool for creating beautiful user interfaces for XAML apps.
- A sleek new look resembling Visual Studio that improves the workflow between the two products.
- A new Blend-exclusive Dark theme that improve the contrast between your content and the Blend user interface
- XAML IntelliSense
- Basic debugging capabilities
- Peek in XAML, which allows you to view and edit XAML controls and resources within the context in which they are used
- An improved file reload experience to minimize workflow interruptions as you work on your projects in both Blend and Visual Studio
- Custom window layouts that can be synchronized across machines that have Blend installed
- Better Solution Explorer and source control support
- Support for NuGet
- Better accessibility in several areas of the Blend user interface, including top level menus, Solution Explorer, and Team Explorer
You, like many other developers today, take advantage of multiple cloud services when developing your applications. For example, you've probably added a cloud backend to your applications to store data, stored your source code in the cloud, or published an application to a store.
In the past, each of these services required a separate sign-in process, and each service managed the signed-in user state separately.
Visual Studio 2015's streamlined sign-in experience is designed to greatly simplify your access to online resources, even when you have multiple Visual Studio accounts. After you sign-in to Visual Studio, you are automatically signed in to all instances of Visual Studio 2015 and Blend on your machine.
In Visual Studio 2015, your account is shared across features so, as long as you have a good token, you can access your Visual Studio Online account(s) from Team Explorer, and resources and websites from your Microsoft Azure subscription in Server Explorer. You’ll also see your Azure resources in the New Project Dialog for Application Insights projects, and you’ll see your Azure Mobile, Azure Storage, Office 365, and Salesforce.com developer accounts in the new Add a Connected Service dialog.
You can work with multiple user accounts in Visual Studio by adding them as you go or through the Account Manager. Then, you can switch between those accounts on the fly when connecting to services or accessing online resources. Visual Studio remembers the accounts you add so you can use them from any instance of Visual Studio or BlendVisual Studio also roams the list of accounts (though not your valuable credentials) with your Personalization account so you can quickly start working with one of those accounts on another device. Of course, you can remove accounts from the Account Settings dialog at any time.
For more details, refer to Work with multiple user accounts.
Visual Studio 2015 has rebuilt the XAML language service on top of .NET Compiler Platform ("Roslyn") so that it can provide you with a fast, reliable, and modern XAML editing experience that includes IntelliSense.
This makes the XAML authoring experience equal to other first-class languages in Visual Studio. This work also sets the stage to deliver powerful feature sets around cross-language refactoring at a much faster cadence.
