Security Advisory Notices

CVE-2019-1077 Visual Studio Extension Auto Update Vulnerability

An elevation of privilege vulnerability exists when the Visual Studio Extension auto-update process improperly performs certain file operations. An attacker who successfully exploited this vulnerability could delete files in arbitrary locations. To exploit this vulnerability, an attacker would require unprivileged access to a vulnerable system. The security update addresses the vulnerability by securing locations the Visual Studio Extension auto-update performs file operations in.

CVE-2019-1075 ASP.NET Core Spoofing Vulnerability

A spoofing vulnerability exists in ASP.NET Core that could lead to an open redirect. An attacker who successfully exploited the vulnerability could redirect a targeted user to a malicious website. To exploit the vulnerability, an attacker could send a link that has a specially crafted URL and convince the user to click the link.

The security update addresses the vulnerability by correcting how ASP.NET Core parses URLs. Details can be found in the .NET Core release notes.

CVE-2019-1113 WorkflowDesigner XOML deserialization allows code execution

A XOML file referencing certain types could cause random code to be executed when the XOML file is opened in Visual Studio. There is now a restriction on what types are allowed to be used in XOML files. If a XOML file containing one of the newly unauthorized types is opened, a message is displayed explaining that the type is unauthorized.

For further information, please refer to https://support.microsoft.com/help/4512190/remote-code-execution-vulnerability-if-types-are-specified-in-xoml.

  • Improved the loading time for very large solutions. The improvement varies based on the size of the solutions.

  • Removed the Convert dialog under File > Convert. This feature was previously deprecated in Visual Studio 2015.

  • Updated the validation rules for the task.vs.json and launch.vs.json schemas, and added descriptions for the properties.

  • Added support for Linux remote debugging using a custom program via launch.vs.json.

Extensibility

  • Users can now use the latest version of the Microsoft.VisualStudio.SDK to target Visual Studio 2019 in your extensions. Remember to only use this version of the SDK if the lowest supported version of Visual Studio is 16.0.
  • Creating new VSIX projects will now contain the 16.0 version of the the Microsoft.VisualStudio.SDK NuGet package.
  • Users can now add tags to your project templates to enable categorization and filtering in the Visual Studio 2019 New Project Dialog. Users can also choose from the built-in tags or their own custom language, platform, and project type tags.
Template tagging

    • shift_left() and shift_right() added to <algorithm>.

  • The following C++20 preview features have been implemented in the C++ compiler, available under /std:c++latest:

    • Increased ability to find function templates via argument-dependent lookup for function call expressions with explicit template arguments (P0846R0).
    • Designated initialization (P0329R4), which allows specific members to be selected in aggregate initialization, e.g. using the Type t { .member = expr } syntax.

  • Lambda support has been overhauled, addressing a large number of long-standing bugs. This change is enabled by default when using /std:c++latest. In other /std:c++* language modes and under the default mode, the new parser can be enabled via /experimental:newLambdaProcessor, e.g. /std:c++17 /experimental:newLambdaProcessor.

  • In-editor documentation for CMake

  • Completions and quick info for built-in CMake commands, variables, and properties make it easier to edit your CMakeLists.txt files.

F# and F# tools

This is a relatively minor release for the F# language and tools, but it's not without some goodies! As with the VS 16.0 update, this release also focused on performance of editor tooling.

F# compiler and F# interactive
  • Added P/Invoke support to F# interactive on .NET Core (#6544)
  • Added a compiler optimization for Span<'T> when used in a for loop (#6195)
  • Added an optimization to avoid an extraneous Some allocations for F# options in various scenarios (#6532)
  • Changed the execution order of expressions used in the instantiation of Anonymous Records to be top-to-bottom, rather than alphabetical, to match the current experience with normal Records (#6487)
  • A bug where very large literal expressions or very large struct declarations could cause the compiler to stack overflow on build has been resolved (#6258)
  • A bug where breakpoints would no longer trigger when debugging a function with an Anonymous Records has been fixed (#6512)
  • A bug where Anonymous Records passed to constructs expecting an obj parameter caused a compiler crash has been fixed (#6434)
  • A bug where for var expr1 to expr2 do ... loops could result in bizarrely valid (and discarded) syntax has been fixed (#6586)
  • A bug where Anonymous Records could not be used properly with events has been fixed (#6572)
  • A longstanding bug where extremely large generated parsers in FsLexYacc (over 100 million lines) has been resolved (#5967
  • A longstanding issue in the Type Provider plugin component of the compiler that could leave the door open for a memory leak caused by a type provider has been resolved (#6409)
  • Support for --pathmap was added to the F# compiler by Saul Rennison, which resolves an issue where the resulting executable from a compilation would include absolute paths to source files in the embedded F# signature file resource (#5213)
  • An optimization to the F# AST that improves its consumption via other tools and enviroments (e.g., Fable) has been added by ncave (#6333)
  • An optimization around traversing information when resolving members has been added by Steffen Forkmann (#4457)
  • An improvement to error messages such that when a type implementation is missing necessary overrides a list of those missing overrides is reported has been added by Gauthier Segay (#4982)
F# tools
  • The Target Framework dropdown for F# projects in the .NET SDK will now include values for all available .NET Core, .NET Standard, and .NET Framework values to ease migrating to .NET Core from .NET Framework on the .NET SDK
  • A bug where renaming generic type parameters produces double backtick-escaped names has been fixed (#5389)
  • A longstanding problem where Type Providers were redundantly reinstantiated, causing massive allocations over time, has been resolved (#5929)
  • A longstanding issue where reading IL needlessly allocated 20MB over a short period of time was been resolved (#6403)
  • A bug where the method GetToolTipText in the F# compiler service could show the same XML signature for several member overloads has been resolved by Vasily Kirichenko (#6244)
F# open source infrastructure

Finally, we improved the contribution experience by doing the following:

  • Completed our build from source process so that the F# compiler and core library can be built with the .NET Core source build repository
  • Removed our dependency on netstandard1.6 so that the entire codebase uniformly targets netstandard2.0 and net472
  • Added a .vsconfig file to the root of the repository so that contributors using Visual Studio don't have to know everything that needs installing up front
  • Rewrote our project's README to remove potentially confusing information, include a quickstart for getting started with contributing, and attempting to be more inclusive in our messaging about the kinds of changes we'd love to take

.NET Productivity

  • There is now experimental intellisense completion for unimported types! Uers now receive intellisense suggestions for types in dependencies in projects even if they have not yet added the import statement to the file. Turn this option on in Tools > Options > Text Editor > C# > Intellisense.

  • Toggle Single Line Comment/Uncomment is now available through the keyboard shortcut (Ctrl+K,/). This command will add or remove a single line comment depending on whether your selection is already commented.
  • Ability to export naming styles with the “Generate editorconfig” button located in Tools > Options > Text Editor > C# > Code Style.
  • Ability to use a new editorconfig code style rule to require or prevent usings inside a namespace. This setting will also be exported when using the “Generate editorconfig” button located in Tools > Options > Text Editor > C# > Code Style.

  • There is now a codefix for making readonly struct fields writable. Place your cursor in the struct name, type (Ctrl+.) to open the quick actions and refactorings menu, and select ‘Make readonly fields writable.’
  • The codefix to add a private field from a constructor and vice versa is easier to discover and will show when any portion of the field name is selected. This refactoring now also offers all possible constructors.

XAML Designer Preview for .NET Core 3.0 WPF development

  • There is an early preview of the XAML Designer for developers building .NET Core 3.0 WPF applications in Visual Studio. Many design-time features will be unavailable at this time. Since this is an early preview, if you encounter issues such as crashes, please submit Visual Studio feedback for the team to improve the experience going forwards.
  • With each update to Visual Studio 2019, we will continue implementing more of the features that were previously available in the XAML Designer for .NET Framework WPF applications.

.NET SDK tooling

This release included a lot of work to unblock the use of WPF on .NET Core:

  • An issue where an error dialog popped up whenever you add a new item to a .NET Core WinForms or WPF project was been resolved (#4486).
  • Support for XAML files in .NET SDK projects (#1467) which includes many smaller items of work aimed at achieving experience parity with old-style .NET projects.
  • Context menu item support for WinForms on .NET Core (#137): Windows Form, User Control, Component, and Class.
  • Context menu item support for WPF on .NET Core (#137): Window, Page, User Control, Resource Dictionary.
  • The Data Sources window is now enabled for .NET SDK projects, enabling common data management scenarios for WinForms (#4479.

Separately, a variety of other fixes were added in this release:

  • .NET SDK projects now support .razor files (#4468).
  • Accessible help text was added to the Debug property page, allowing it to be read by screen readers (#4568).
  • We added a setting that allows you to disable double-click to open a project file (#4493).
  • The context menu option to edit a project file no longer includes the project name, fixing an issue where the context menu could get too wide due to a very long project name (#1492).
  • A bug where creating a Data Source with the Data Binding UI created two .datasource fileas has been fixed (#4485).
  • A bug where using linked files could cause the up-to-date checker to fail has been resolved (#4580).
  • A variety of bugs involving package resolution and the display of their resolved/unresolved state in the Dependencies node have been fixed (#2924,#4577).

You can see a full list of closed issues by going to the 16.1 milestone on GitHub.

Xamarin

  • Updated the default Android Experience to API 28 for templates, device creation, installers, and more.
  • IntelliSense on Windows now shows recommendations for design-time attributes when writing Xamarin.Forms XAML.
