Support Timeframe

Visual Studio 2017 version 15.9 is the final supported servicing baseline for Visual Studio 2017 and has entered the extended support period. Enterprise and Professional customers needing to adopt a long term stable and secure development environment are encouraged to standardize on this version. As explained in more detail in our lifecycle and support policy, version 15.9 will be supported with security updates through April 2027, which is the remainder of the Visual Studio 2017 product lifecycle.

Because Visual Studio 2017 is now in extended support, all administrator updates now cover all minor version ranges of the product. This means that all security updates delivered through the Microsoft Update Catalog or Microsoft Endpoint Manager will update the client to the latest secure version of the Visual Studio 2017 product.

.NET Core 2.1 is out of support as of August 21, 2021

An attacker who successfully exploited the vulnerability could execute arbitrary code in the context of the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. To exploit the vulnerability, an attacker must place a malicious DLL on a local system and convince a user to execute a specific executable. The security update addresses the vulnerability by correcting how the Visual Studio C++ Redistributable Installer validates input before loading DLL files.

CVE-2019-0757 .NET Core NuGet Tampering Vulnerability

A tampering vulnerability exists in NuGet software when executed in a Linux or Mac environment. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that an attacker can login as any other user on that machine. At that point, the attacker will be able to replace or add to files that were created by a NuGet restore operation in the current users account.

.NET Core updates have released today and are included in this Visual Studio update. The security update addresses the vulnerability by correcting how NuGet restore creates file permissions for all files extracted to the client machine. Details about the packages can be found in the .NET Core release notes.

CVE-2019-0613 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.

CVE-2019-0546 Visual Studio Remote Code Execution VulnerabilityA remote code execution vulnerability exists in Visual Studio when the C++ compiler improperly handles specific combinations of C++ constructs. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. The security update addresses the vulnerability by correcting how the Visual Studio C++ compiler handles certain C++ constructs.

CVE-2018-8599 Diagnostics Hub Standard Collector Service Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists when the Diagnostics Hub Standard Collector Service improperly handles certain file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges. To exploit this vulnerability, an attacker would require unprivileged access to a vulnerable system. The security update addresses the vulnerability by ensuring the Diagnostics Hub Standard Collector Services properly impersonates file operations.

New Features in 15.9

Install

We made it easier to keep your installation settings consistent across multiple installations of Visual Studio. You can now use the Visual Studio Installer to export a .vsconfig file for a given instance of Visual Studio. This file will contain information about what workloads and components you have installed. You can then import this file to add these workload and component selections to another installation of Visual Studio.

Debugging

We have added support for consuming the new portable-pdb based symbol package format (.snupkg). We have added tooling to make it easy to consume and manage these symbol packages from sources like the NuGet.org symbol server.

C++

F#

F# Compiler

F# Tools

F# Open Source Repository

The VisualFSharpFull project is now set as the default startup project, eliminating the need to manually set that before debugging. Thanks, Robert Jeppesen!

JavaScript and TypeScript Language Service Support

SharePoint 2019 Support

We added new templates that allow you to create projects for SharePoint 2019. You will have the ability to migrate existing SharePoint projects from both SharePoint 2013 and SharePoint 2016 to the new project template.

Visual Studio Tools for Xamarin

Visual Studio Tools for Xamarin now supports Xcode 10, which allows you to build and debug apps for iOS 12, tvOS 12, and watchOS 5. See how to get ready for iOS 12and our introduction to iOS 12for more details on the new features available.

Initial Xamarin.Android Build Performance Improvements

Xamarin.Android 9.1 includes initial build performance improvements. See our Xamarin.Android 15.8 vs. 15.9 build performance comparison for more details.
