Visual Studio for Mac Preview Release Notes

Visual Studio for Mac is a new member of the Visual Studio family focused on mobile and cloud development using Xamarin and .NET Core.

Overview

Visual Studio for Mac is an evolution of Xamarin Studio, and includes all the functionality of Xamarin Studio 6.2.

Many changes have been made to the look-and-feel, terminology and default settings to to align more closely with Visual Studio, while remaining a Mac-centred development experience.

Core Functionality

Visual Studio for Mac has everything you would expect from a modern IDE, including a full-featured source editor, code search and navigation, a powerful debugger, a customizable workspace, git integration, and a rich extension system.

Other features include:

  • Roslyn-based C# IntelliSense, refactoring, analyzers and code fixes
  • NuGet-based package management
  • Visual Studio compatible project format
  • MSBuild build engine
  • Integrated unit testing
  • Support for F# out-of-the-box

Xamarin Platform

First-class support for the Xamarin Platform allows you to develop rich native experiences for iOS, Android and Mac. The Xamarin.Forms cross-platform library helps you share XAML-based UI code between iOS, Android and UWP (though UWP is not supported on Mac) without limiting access to native functionality.

This includes:

  • Building, deployment, debugging and profiling
  • Drag-and-drop UI designers for iOS and Android
  • Live preview for Xamarin Forms
  • .NET Standard compatible framework
  • Bindings to native APIs

New Features

The following features are new in Visual Studio for Mac Preview:

.NET Core Support

.NET Core is a platform for creating applications that run on Windows, Linux and Mac. Visual Studio for Mac has support for loading, creating, running and debugging .NET Core projects.

In order to run .NET Core projects the .NET Core SDK should be downloaded and installed.

.NET Core support includes:

  • C# and F# IntelliSense.
  • .NET Core project templates for console, library and web applications.
  • Full debugging support, including breakpoints, call stack, watch window, etc.
  • NuGet PackageReferences and MSBuild-based restore.
  • Integrated unit testing support for running and debugging tests with the Visual Studio Test Platform that is included with the .NET Core SDK.
  • Migration from old project.json format.

Web Tooling

Visual Studio for Mac adds new web tooling support for HTML, CSS and JSON files.

HTML

  • New HTML template.
  • Improved smart indent and formatting.
  • Improved colorization.
  • Improved tag Intellisense.
  • Entity IntelliSense.
  • Attribute and value IntelliSense.
  • Code folding (must be enabled).
  • Comment/uncomment.
  • Improved Undo.
  • Unminify command.
  • Improved Code Templates (snippets).
  • Surround selection with <div>.
  • Option up/down moves selected text up/down.

CSS

  • Improved smart indent and formatting.
  • Improved colorization.
  • Selector IntelliSense.
  • Directive IntelliSense.
  • Improved Attribute and Value IntelliSense.
  • Code folding.
  • Comment/uncomment.
  • Many Code Templates (snippets).
  • Option up/down moves selected text up/down.

JSON

  • Schema picker with access to schemastore.org
  • Validation from schema
  • IntelliSense from schema
  • Improved smart indent and formatting
  • Improved colorization
  • Comment/uncomment
  • Quote injection and brace matching
  • Option up/down moves selected text up/down

Multiplatform App Templates

The Multiplatform Forms App and the Native App project templates now offer a quick way to create a multiplatform mobile app and its cloud backend.

These templates create multiple projects: a Xamarin.iOS app project and a Xamarin.Android app project that share code via a shared project, and a .NET Core Web API project that implements a back-end service for the apps.

Publishing ASP.NET Core Web Apps to Azure App Services

It is possible to publish your ASP.NET Core web apps to Azure App Services.

In this release, publishing to Azure is the only publish destination but we will be adding more in later releases.

To publish your web app, select the Publish | Publish to Azure command from the Solution Pad or from the Project menu. Then choose the App Service you wish to deploy to, or create a new Azure App Service. Output from the publishing will be logged to a Publish output pad and a publishing profile will be created under Properties\PublishProfiles in the project.

All publish profiles defined in the project will be shown as options within in the Publish menu so that you can deploy again without having to select the App Service a second time.

Multi-Process Debugging

In Xamarin Studio, projects have Project Run Configurations which specify options and arguments for running your project. A dropdown in the toolbar lets you view and change the current active Run Configuration.

Visual Studio for Mac extends this by adding Solution Run Configurations which allow multiple projects to be launched at once. You can create solution run configurations in the Solution Options dialog.

Using solution run configurations, you can debug multiple projects at once. This is very useful for debugging how a mobile app interacts with its backend service.

TextMate Bundles

Visual Studio for Mac has support for TextMate language bundles, which you can use to add:

  • Editor color themes
  • Code snippets
  • Grammars for new languages, enabling highlighting and basic IntelliSense

You can add TextMate bundles in Preferences > Text Editor > Language Bundles.

iOS

Audio Unit Wizard

The new Audio Unit Extension wizard adds 3 options to customize the Audio Unit project template's plist.

  • Audio Unit Type
    • Instruments
    • Generator
    • Effect
    • Music effect
  • Subtype Code: has to be 4 characters exactly
  • Manufacturer Code: has to be 4 characters exactly

Audio Unit Wizard

Remove TLS Provider option

TLS Provider is not needed in the iOS build options anymore because:

  1. AppleTLS is the default since C7 and support up to TLS 1.2.
  2. MonoTLS is limited to SSLv3 and TLSv1: both are being deprecated.

Note: Xamarin.iOS 10.4 release notes already mention MonoTLS is deprecated and that it will be removed in the future.

Mac/iOS API issue analyzer

  • Fix duplicated marker when analyzer is triggered.
    We used to answer to too many SyntaxKind in RegisterSyntaxNodeAction.
    This resulted in the source analysis marker to show up on both the object and the method, duplicating the message.
  • Get the "message" (piece of information in the framework explaining why the API is deprecated/obsolete) from the attribute.
    We now append that extra information to the different availability messages.
  • Updated all availability messages to improve clarity.
  • Use the symbol's name in the availability message.
    This also improves clarity, moving from:
    API Usage Issue: this API requires iOS 10.0 or later
    to:
    'MyMethod' is only available on iOS 10.0 or newer

watchOS extension wizard

In Xcode 8.3, Apple introduced watchOS extensions (similar to the iOS ones), starting with the Intents extension (Siri).

The extension wizard has been upated to support watchOS extensions and we now have a dedicated Intents extension template.

watchOS extension wizard

Other improvements and bug fixes

  • Handle Deprecated and Obsoleted attributes in autocompletion window. This allows Xamarin.iOS obsoleted and deprecated APIs to be shown as struck through.
  • We now show a progress bar when deploying to device. This is especially useful for watchOS. (Requires Xamarin.iOS 10.5.0.323+).
  • We now use known OS versions from Xamarin.iOS to populate the deployent target dropdowns.
    The two advantages are that we can give you the exact minimum version for each App Extensions type, as well as avoid showing OS versions, based on Xcode, that Xamarin.iOS does not yet support.

Android

  • New SDK Manager

Recently Google deprecated the SDK manager that ships with the Android SDKs in favor of using the SDK manager within Android Studio. Visual Studio for Mac now also includes its' own SDK manager.

androidSdkManager

  • Deploying your project to device or emulator is now done via the /t:Install msbuild target. Previously Visual Studio for Mac would use it's own internal logic for deploying applications to devices but now it uses same common targets that you can employ from Terminal, or that are used in Visual Studio on Windows. One of the benefits of this is that there are now better logs available to diagnose deployment issues.

  • class-parse is now the default for new binding projects. class-parse can parse Java bytecode directly wihout the need for a JVM and is able to extract parameter names from Java bytecode which contains debug symbols, e.g. bytecode compiled with javac -g. 'class-parse' also doesn't "skip" classes which inherit from or contain members of unresolvable types.

Accessibility

  • This version of Visual Studio for Mac contains support for assistive technologies such as Voice Over. Many parts of the user interface, such as the editor and solution explorer, have been made accessible through these technologies, however it is still a work in progress and futher improvements will be made in coming releases.

Feedback

Please report any problems you encounter with the Visual Studio for Mac Preview using the Help > Report a Problem menu.

If there is any functionality that you would like to be changed or added to Visual Studio for Mac, please use the Visual Studio for Mac UserVoice to share your ideas and vote on suggestions made by other people. You can also access this from Help > Provide a Suggestion.

We can't respond to all feedback directly, but we do read it all and it very much helps us prioritize improvements to make Visual Studio for Mac work better for you.

System Requirements

Visual Studio for Mac Preview requires macOS 10.11 or later. For Xamarin development there are additional requirements listed here.

Side by Side Installation with Xamarin Studio

Visual Studio for Mac can be installed side by side with Xamarin Studio.

However, Visual Studio for Mac requires Mono 5.0, and installing or updating the stable or beta version of Xamarin Studio will downgrade Mono to an older version.

You can work around this by switching Xamarin Studio to the alpha update channel, or by opting out of Mono 4.6 downgrades in the Xamarin Studio update dialog. If you need to reinstall Mono 4.8, you can get it here.

Known Issues

This is a preview release, and ships with several known issues and limitations that will be addressed in future updates.

  • 54993 "The root assembly ... conflicts with another assembly" build error can occur for Xamarin.iOS projects in Xamarin.VisualStudio 4.4.0 on Windows due to the incompatible Xamarin.iOS 10.10.0 Alpha version that is installed on the Mac by the latest Visual Studio for Mac Preview. Visual Studio 2015 and 2013 users can optionally update to the Alpha updater channel to get the compatible Xamarin.VisualStudio 4.5.0 Alpha version. For VS 2017 users and users who do not wish to use the Alpha versions on Windows, please refer to the bug report for a few other options for how to resolve this issue.
  • Debugging F# .NET Core projects is not working with Mono 5.
  • Changes in files on disk are not picked up by wildcards until the project is reloaded.
  • There are very few ASP.NET Core specific file templates.
  • The first time you build an Android project that uses the Google Android Support Libraries, the build may appear to hang with no output while the download takes place.
  • The new Multiplatform Forms App and Native App templates currently require the app to be manually configured with the address of the service on the host machine, except when using the iOS Simulator.
  • The Xamarin.Forms XAML previewer can cause Visual Studio for Mac to become unresponsive.
  • The File Nesting extension version 0.1 causes NuGet package restore to fail with Visual Studio for Mac Preview. This extension should be disabled in the Extension Manager until a new version is published that is compatible.
