Release Date: August 14, 2017 - Visual Studio for Mac

This release focused on bug fixes and introduces the following new features:

  • Support for building applications using .NET Core 2.0.
  • iOS signing workflow updates.

.NET Core 2 support

Visual Studio for Mac supports building .NET Core 2.0 applications, including libraries, console apps, as well as web applications and services with ASP.NET Core.

Note that the .NET Core 2.0 SDK needs to be installed via a separate download to enable .NET Core 2.0 development in Visual Studio 2017 for Mac Version 7.1. You can get it at Visual Studio enables side-by-side support of multiple .NET Core SDKs. This also means you can experiment with the latest daily build of the .NET Core SDK, while also developing with the latest public releases.

iOS signing workflow updates

This release introduces the ability to create required signing artifacts for iOS and tvOS apps. With Visual Studio for Mac, it's possible to:

  • Create new signing identities and install them to the local Keychain.
  • Create new Provisioning Profiles.
  • Add a new signing identity to an existing profile.
  • Provision new devices: register a device in the Apple Developer Portal and add them to a provisioning profile.

To try out these new signing features right-click on your project and browse to Options > iOS Bundle Signing.

Using the Signing Identity section

Before signing, you must satisfy the following criteria:

  • A valid certificate (not revoked) is displayed on the Apple Developer Portal in the "Certificates" section.
  • The certificate is issued for selected team/developer.
  • Both certificate and private key should be installed in your local Keychain.
  • Certificate should not be expired.

Use Create signing identity... option of the dropdown if no identities are available on your current machine.

Using the Provisioning Profile section

In order to be shown in the "Provisioning Profile" drop-down profile must satisfy the following criteria:

  • Not expired.
  • Valid (include registered devices and valid certificates).
  • Match current distribution type (Debug or Release based on switches at the top).
  • Match bundle identifier. Wild card profiles with a matching pattern will be also displayed in this list.

Use Create provisioning profile... item of the dropdown if no profiles were found.

If you need to switch back to the previous version of signing controls, and set the provisioning profile and signing identity manually, set the team to None. New signing controls will be replaced with old ones. However, we strongly encourage you to try new functionality and provide us with feedback in case of any problems.


  • Provisioning profiles created in Visual Studio for Mac will not take into account entitlements selected in your projects (Entitlements.plist). This functionality will be added in future versions of the IDE.
  • Distribution provisioning profiles by default will target App Store. In House or Ad Hoc profiles should be created manually.

Fixes in this release

Android SDK Manager

  • Android SDK Manager is now integrated within Visual Studio Preferences instead of being an external application.
  • Fixed: The Android SDK Manager shows the wrong component status after an aborted installation.
  • Fixed: Android SDK Tools installed but not selected if update is available which can result in the component being uninstalled unintentionally.

Performance Improvements

  • Optimized background work done while typing.
  • Improved load time of opening a solution.
