Security Advisory Notices

CVE-2019-1211 Git for Visual Studio Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists in Git for Visual Studio when it improperly parses configuration files. An attacker who successfully exploited the vulnerability could execute code in the context of another local user. To exploit the vulnerability, an authenticated attacker would need to modify Git configuration files on a system prior to a full installation of the application. The attacker would then need to convince another user on the system to execute specific Git commands. The update addresses the issue by changing the permissions required to edit configuration files.

IDE

  • Hold down the Alt key + a letter indicated by an underline in the word to quickly jump to different actions in the start window and new project dialog screens for complete keyboard accessibility.
  • Take any file type including solution files and drop them on to the start window when you launch Visual Studio to load the file.
  • Resize the start window and new project dialog by dragging the edges. Visual Studio remembers changed sizes between invocations of the windows. Ability to maximize the windows by double clicking in the title bar area and minimize the windows by clicking on the task bar icon when in their launch states.
  • Access the Developer Command Prompt and Developer Power Shell by either going to “Tools > Command Line” or by searching for them via the Visual Studio Search. Accessing them from within the IDE, automatically sets their path according to the currently opened solution or folder.
  • The Preview Features tools options page has a new look that provides more information of the feature. Check this page for new features and to provide feedback on features.
  • Preview Feature: Enable the “Standard tool window layout” preview feature to improve the startup time for Visual Studio by minimizing the impact of opening tool windows.
  • Backup files are now saved to a temporary folder to avoid using unnecessary storage space in My Document folders that are synchronized with OneDrive

WPF/UWP Tooling

Customers building WPF/UWP applications will see the following improvements in Visual Studio XAML tooling:

XAML Debugging Tools:

  • XAML C# Edit & Continue is now known as XAML Hot Reload: XAML C# edit & continue for WPF/UWP customers is now known as XAML Hot Reload, this new name is intended to be better aligned with how the feature actually works (since no pause is required after a XAML edit is made) and match the similar functionality in Xamarin.Forms.
  • XAML Hot Reload available/unavailable: The in-app toolbar has been updated to indicate if XAML Hot Reload is available/unavailable and link to the related documentation. Before this improvement customers had no way to know if XAML Hot Reload was working without trying to first use the feature, which was leading to confusion.
  • In-app toolbar now themed: The in-app toolbar is now styled according to the Visual Studio selected theme colors.

  • In-app toolbar element selection behavior changes: We’ve updated the behavior of the in-app toolbar feature “Enable selection” for selecting elements within the running app. With this change the selector will stop selecting elements after you have selected your first element. This brings it in line with similar tools such as F12 browser tools and is based on customer feedback.

Test Explorer

The Test Explorer now has significant UI improvements including better handling of large test sets, more natural filtering, discoverable commands, and the addition of customizable columns that let the user fine-tune what test information is displayed.

Updated Test Explorer UI

  • Users can customize what information is displayed by tests at a glance by selecting what columns are displayed! The Duration column can be displayed when investigating performance and use the Message column when comparing results. This table layout mimics the Error List table in its customizability. The columns can also be filtered using the filter icon that appears when hovering over the column header.

  • Users can specify what is displayed in each tier of the test hierarchy. The default tiers are Project, Namespace, and then Class, but additional options include Outcome or Duration groupings.

  • The test status window (the pane below the test list that displays the messages, output, etc.) is much more usable. Users can copy substrings of text, and the font-width is fixed for more readable output.
  • Playlists can be displayed in multiple tabs and are much easier to create and discard as needed.

  • Live Unit Testing now has its view in the Test Explorer. It displays all tests currently included in Live Unit Testing (aka. the live test set), so testers can easily keep track of Live Unit Testing results separate from the manually run test results.
  • There is a target framework column that can display multi-targeted test results.

Deprecated items

  • The project creation wizard for creating new Azure DevOps Server (TFS) projects has been removed from the Team Explorer. Users who want to create a new project can still go to their Azure DevOps Server instance and create a project through the web UI.
