Editor

  • For folks who want a less crowded experience, line spacing can be modified by searching for 'line spacing' in Visual Studio Search (Ctrl+Q). The option is under Text EditorGeneral.
  • Find in Files and Find all References have a control to keep results. Based on feedback from our community, we've added an option to toggle the 'Keep Results' option to on by default. This option can be found by searching for 'keep search results by default' in Visual Studio Search (Ctrl+Q). The option is under EnvironmentFind and Replace. Note that users are currently limited to 5 results for Find in Files and 5 more results for Find all References.
  • A new option in Find in Files allows users to run additional searches and append those results to a previous search.

  • Log files and the Test Explorer support Ctrl PgUp/PgDn for navigating the cursor and Shift+Ctrl PgUp/PgDn for selection.
  • The log file editor is now using the IVsTextView interface which means it will now be able to open very large text files. This should eliminate the need for users to Copy All truncated logs and open them in a separate editor such as Notepad. For MSTest, we now also include a single log file that aggregates all the output instead of only having individual log files for each data row.
  • IntelliSense completion updates
  • Go to Definition support for generic components

.NET Productivity

  • There is now a completion option that automatically inserts arguments when writing a method call. This feature is off by default so you will need to enable it in Tools > Options > Text Editor > C# > IntelliSense and select Tab twice to insert arguments (experimental). Start writing a method call and press tab twice (tab+tab). Notice that the method call includes arguments based on the method’s default values. You can then use parameter info to cycle through the list of arguments that you would like inserted by pressing the up and down arrow keys. You can also start typing an argument to bring up the IntelliSense completion list and type semicolon which will commit the argument and add a semicolon to the end of the method call.
Method call argument completion

In this release we also added the following enhancements to the Edit and Continue (EnC) debugging experience in Visual Studio:

  • It is now possible to apply changes in code that is within a partial class.
  • You can now apply changes within a Source Generated) file.
  • It is now possible to add and/or change a using directive.
  • Improvements in reliability and lower memory consumption.

All three changes are available anywhere where EnC is supported today and work with both C# and Visual Basic source files.

  • IntelliSense completion now filters for HTML components, TagHelper elements, and C# attributes:
Razor IntelliSense filters
  • IntelliSense completion for C# overrides.
  • Go to Definition support for generic componenets.
  • New code style configuration options for tabs vs spaces. These code styles will be respected when typing, formatting, and creating a new Razor file. You can configure tabs and spaces in Tools > Options > Text Editor > Razor (ASP.NET Core) > Tabs.
  • The Razor text editor in Tools Options has been renamed from ASP.NET Core Razor Language Services to Razor (ASP.NET Core).

To enable the new preview Razor editor, go to Tools > Options > Environment > Preview Features, select Enable experimental Razor editor, and then restart Visual Studio.

XAML Tooling Improvements (WPF & Xamarin.Forms)

Xamarin.Forms

In this release we’ve made two small improvements to XAML IntelliSense and XAML Hot Reload for Xamarin.Forms customers. Hot Reload “change only” will no longer report false errors for:

  • Setters in VisualStateManager referencing properties without specifying type, e.g. .
  • Merged ResourceDictionaries not wrapped into <ResourceDictionary.MergedDictionaries> element

Example:

XAML Sample Data

In this release we've further enhanced the XAML Designer's design-time data capability by introduced a new way to add generic sample data to your ItemsControls. This feature works for ListBox, ListView and DataGrid in WPF only.

Visual studio mac os
  • Sample Data can be enabled by setting d:ItemsSource='{d:SampleData}' on your ListBox, ListView or DataGrid
  • This will populate your control in the designer only with a set of 5 items that match your DataTemplates and Binding Paths
  • You can change how many items are generated using the ItemCount property, for example: d:ItemsSource='{d:SampleData ItemCount=3}'
Sample Data enabled on a ListBox

Docker Tools

Compose
  • Docker Compose tooling in Visual Studio now provides the ability to run any combination of services defined in your Compose files. Either open the Debug dropdown or right-click on your docker-compose project and select Manage Docker Compose Launch Settings to get started.
Manage Docker Compose Launch Settings
Containers Tool Window

In this release, we made additions to the Containers tool window to make it easier to view and interact with containers and images. Just navigate to View > Other Windows > Containers to try out the new features.

Live Share Visual Studio Mac
  • Containers are now grouped by Compose project. This makes it simple to tell which containers represent your application. Also shown, we added a Labels tab in Containers so you can easily see which labels you are using during development.

  • We also added a Labels tab for images.
Imagese Label tab
  • The new Volumes tab allows you to see the volumes of a running container and even open the files in Visual Studio.

  • We now support the ability to tag an image from the Containers tool window. From Images, right-click an image and select Tag.
Tagging an image

Test Experience Accessibility Improvements

  • Console.Writeline now shows in the Test Explorer! Long output appears as a collapsible section in the test detail summary pane. Output over a certain length displays the first several lines and is then truncated with an option to open the test log in a separate window. The stacktrace truncates if there are over 20 frames and will then only show the first and last 10 frames. An important part of the truncation design was also focused on reducing VS freezes when test runs have large output. Tests that have large output will no longer block the UI thread.
Test output includes Console.Writeline
  • Test output can now preserve tags so hyperlinks and stacktrace links are navigable even from the log files. These links are now keyboard friendly as well.
Test output preserves hyperlinks and stacktraces
Test logs also preserve hyperlinks and stacktraces
  • Log files are created for a single test result when output is over 300 characters or if there are over 10 files attached to the test result. Log files can also now open in preview so it’s easier to manage your tabs. Log files and the Test Explorer support Ctrl PgUp/PgDn for navigating the cursor and Shift+Ctrl PgUp/PgDn for selection.
Test logs are easier to select with keyboard shortcuts
  • The log file editor is now using the IVsTextView interface which means it will now be able to open very large text files. This should eliminate the need for users to Copy All truncated logs and open them in a separate editor such as Notepad. For MSTest, we now also include a single log file that aggregates all the output instead of only having individual log files for each data row.

Details of What's New in Visual Studio 2019 version 16.10 Preview 1

.NET Productivity

  • We added a Remove Unused References command that allows you to clean up project references and NuGet packages that have no usage. This option is off by default so you will need to enable it in Tools > Options > Text Editor > C# > Advanced and select Show “remove Unused References” command in Solution Explorer (experimental). Once the option is enabled the Remove Unused References command will appear in the right-click menu of a project name or dependencies node in Solution Explorer:
Remove Unused References command

Selecting Remove Unused References will open a dialog where you can view all references that are going to be removed with an option to preserve the ones that you want to keep:

Remove Unused References dialog
  • We added a new command called Smart Break Line that automatically inserts a set of braces and places the caret within those braces when using Shift+Enter as a commit character. Smart Break Line works for all type declarations that require braces as well as properties, events, fields, and object creation expressions. The example below shows Smart Break Line used on a class and a field. If the field doesn’t have a semicolon at the end, typing Shift+Enter will convert the field to a property by adding a set of braces. You can press Shift+Enter again to undo the commit which will also automatically add a semicolon at the end of the field:
Smart Break Line
  • There is now a refactoring to simplify LINQ expressions which will remove the unnecessary call to the Enumerable for the .Where() method to help improve performance and readability. Place your cursor on the LINQ expression. Press (Ctrl+.) to trigger the Quick Actions and Refactorings menu. Select Simplify LINQ expression.
Simplify LINQ Expression
  • There is now IntelliSense completion for Enum values when a type is known even if the Enum name is not entered.
IntelliSense completion for Enum values
  • We added a new IntelliSense completion mode setting that gives you the ability to set default completion options. This new setting is available in Tools > Options > Text Editor > Advanced > Default IntelliSense completion mode where you can choose from the following options: Last used which will preserve the last setting you used with Ctrl+Alt+Space, Tab-only which will only complete on tab, and Automatic which is currently the default behavior that will complete on punctuation and special characters.
