For a pull request I opened on the Xamarin.Forms repository, I had implemented all supported platforms but one: Tizen. For some reason, I had tried to get Tizen up and running on a (virtual) Windows machine where I couldnât get the emulator to work. One member of the Tizen team reminded me that you could also develop and run Tizen apps on your Mac. In this post, I will show you how to get started with Tizen, focussed on Xamarin.Forms.
Setup the Tizen Environment
Learn about Visual Studio, Visual Studio for Mac, Xamarin and Xamarin.Forms Announcements from Microsoft Build 2018 from sessions by Mikayla Hutchinson, Miguel de Icaza, James Montemagno and David Ortinau. Oct 16, 2018 Since it was released a little more than a year ago, Visual Studio 2017 for Mac has grown from being an IDE primarily focused on mobile application development using Xamarin to one that includes support for all major.NET cross-platform workloads including Xamarin, Unity, and.NET Core.
If you have not done so already, install Visual Studio Code (VS Code), you will need it for this. I already had it installed because itâs a great tool and I already used it to create a Chrome extension earlier. To install the Tizen development tools, simply start VS Code and go to the Extensions pane as you can see in the image underneath.
In this pane, simply search for Tizen and install the Tizen .NET extension. It will then ask you if you have already installed a Tizen baseline SDK or Tizen Studio before. Since youâre reading this, I guess you havenât so click No. If you have, click yes and enter the existing path to the installation. If you press No, it will first install all the required packages for Tizen. This may take a little while. You can keep your eye on the progress from the VS Code console window that comes up.
After the installation the SDK path is set automatically and we can continue with installing and preparing the rest, starting with an emulator we can use.
Installing the Emulator(s)
In VS Code there is a so-called Command Palette. You should be able to activate it with CMD + Shift + P on your Mac or go to View > Command Palette. In the text box that comes up, start typing âTizen packageâ and it will suggest to you to launch the Tizen package manager.
The Tizen Package Manager should come up and you will see a list of different form factors that you can install: Mobile, Wearable or TV and each with a different SDK version. At the time of writing, 5.0 seems to be the latest available version. I donât think it doesnât matter very much which one you chose, it all runs on the same platform so it should look and work more or less the same. If you want to test it on all form factors, install one of each. For now, I will stick with Mobile. To install the necessary tools and SDK, simply click the Install button corresponding to your choice.
Wait until all required packages are installed and after that, we can start looking into creating or running our application! It might take a while though⦠Better get a coffee!
Starting Actual Development
So, here is where things are starting to fall apart for a bit. At least, when doing Xamarin development, but I have a feeling this is also true for plain Tizen development. Letâs get a few things sorted first.
Tizen is a platform on its own, just like iOS, Android, UWP, etc. and it happens to be that there is Xamarin.Forms support for it. But it is perfectly possible to create native Tizen apps. You can use Tizen Studio and the emulators, etc. Since I was only interested in implementing a feature in Xamarin.Forms for Tizen, I didnât really look into the native tooling.
When you followed the steps above, you will get all the Tizen tooling that is needed for native Tizen development, but these can also be used together with Visual Studio Code with the extension we installed there. Also, the Tizen Xamarin.Forms project will also load in Visual Studio for Mac, but you canât launch the emulator from there, so there is no way to debug or test your code directly from VS for Mac.
Visual Studio Code vs. Visual Studio for Mac
On my Mac, I basically use Visual Studio for Mac all the time. It works for everything I want to do, except some Windows specific stuff. It even works for Tizen as I just mentioned. You have IntelliSense available and together with the documentation, you can get started with the Tizen APIs pretty quickly. However, you do want to verify if whatever you built works. At the time of writing, there is, unfortunately, no integration with VS for Mac and Tizen.
That is why the (very friendly, I might add) people of the Tizen team pointed me to Visual Studio Code and the extension that is available. While I did get everything set up pretty quickly, still debugging and running is a bit of a problem. Also, developing works, since you will get IntelliSense and everything, but building the full Xamarin.Forms solution from VS Code didnât seem to work. Maybe I did something wrong, but I couldnât get it to work.
Now I was stuck. I couldnât run the emulator from VS for Mac, but the project did build there and I couldnât build my project from VS Code but I could run the emulator there.
I decided that the working emulator was beyond my influence and stuck with VS Code, focussing on making the build work. All code was implemented in theory, so I just needed to verify
Getting the Tizen Project to Build
I quickly decided that I didnât need to build the whole Xamarin.Forms solution for just the Tizen app, so I went and loaded just the Xamarin.Forms.ControlGallery.Tizen in my workspace in VS Code. This is the testing app that the Forms team drafted up for automated UI tests and manual verification of (new) Xamarin.Forms features.
Going over the available Tizen-related commands in Visual Studio (you can see them in the image below), I noticed there were a couple of different candidates for making this work. The most ideal one being: âRun debug modeâ. Unfortunately, it didnât work. It did successfully build the project though, so that was a first victory. I noticed the emulator didnât even come up. Letâs fix that first.
Victory!
Through the âLaunch Tizen Emulator Managerâ command the Emulator Manager was started again (if you still had it open, that is fine too). I started the installed emulator and wait until it booted. Now, I tried again and ran the âRun debug modeâ. However, it still didnât work. It will fail with an error message like: âFailed to install the Tizen debug package. (Make sure the path info of the LLDB packages is correct.â and then some path name. You can see the errors in the image below. From talking to the Tizen team this is a known problem and they are working on it. However, this just means that the debugging session was not started. If you go to the emulator, the app is actually installed and you can run it, victory!
After trying a couple of more things, I discovered you can also run some separate commands like building the Tizen project and then run just the âInstall a Tizen .NET applicationâ command to install it on the emulator. While this is of course far from an ideal debugging experience, it at least let me verify if my changes worked and make some adjustments. It just takes a bit more time. I am confident the Tizen team will take this up soon and fix it for a better experience.
Summary
With this Tizen environment up and running, I can start implementing all the new Xamarin.Forms features also for that platform which is pretty awesome. I hope there is support coming for Visual Studio for Mac so I wonât have to switch IDEs halfway through the process (and once more for the Windows WPF/UWP support) but besides from that, setting up and running is a pretty smooth experience.
I think Tizen support on Windows is a lot better at this point. There is a Visual Studio extension available, and you should be able to debug without any problems. But. I am using a Mac and have a virtualized Windows installation with Parallels. With all the virtualization in virtualization (virtualizationception) the Tizen emulator doesnât run but gets stuck on âBooting the kernelâ. That is why I could not use it for development, unfortunately. But, if you have a dedicated Windows machine that you can use, I recommend to turn to that. You will have to boot it to work with Xamarin.Forms UWP and WPF anyway ðŸËâ°

View the latest Visual Studio for Mac release notes on docs.microsoft.com.
Visual Studio for Mac is a new member of the Visual Studio family focused onmobile and cloud development using Xamarin and .NET Core.
Overview![]()
Visual Studio for Mac is an evolution of Xamarin Studio, andincludes all the functionality of Xamarin Studio 6.2.
Many changes have been made to the look-and-feel, terminology and defaultsettings to to align more closely with Visual Studio, while remaininga Mac-centred development experience.
Core Functionality
Visual Studio for Mac has everything you would expect from amodern IDE, including a full-featured source editor, code search andnavigation, a powerful debugger, acustomizable workspace, git integration, and a rich extension system.
Other features include:
Xamarin Studio Vs Visual Studio For MacXamarin Platform
First-class support for the XamarinPlatform allows you to develop rich nativeexperiences for iOS, Android and Mac. The Xamarin.Forms cross-platformlibrary helps you share XAML-based UI code between iOS, Android and UWP(though UWP is not supported on Mac) without limiting accessto native functionality.
This includes:
New Features
The following features are new in Visual Studio for Mac Preview:
.NET Core Support
.NET Core is a platform for creating applicationsthat 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 bedownloaded and installed.
.NET Core support includes:
Web Tooling
Visual Studio for Mac adds new web tooling support for HTML, CSS and JSON files.
HTML
CSS
JSON
![]() Multiplatform App Templates
The Multiplatform Forms App and the Native App project templates now offer a quick way to create amultiplatform mobile app and its cloud backend.
These templates create multiple projects: a Xamarin.iOS app project anda 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 toa Publish output pad and a publishing profile will be created under PropertiesPublishProfiles 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 havingto select the App Service a second time.
Multi-Process Debugging
In Xamarin Studio, projects have Project Run Configurations which specify optionsand arguments for running your project. A dropdown in the toolbar lets youview and change the current active Run Configuration.
Visual Studio for Mac extends this by adding Solution Run Configurationswhich allow multiple projects to be launched at once. You can create solutionrun configurations in the Solution Options dialog.
Using solution run configurations, you can debug multiple projectsat once. This is very useful for debugging how a mobile app interacts withits backend service.
TextMate Bundles
Visual Studio for Mac has support for TextMate language bundles, which youcan use to add:
Microsoft Visual Studio For Mac
You can add TextMate bundles in Preferences > Text Editor > Language Bundles.
iOSAudio Unit Wizard
The new Audio Unit Extension wizard adds 3 options to customize the Audio Unit project template's plist.
Remove TLS Provider option
TLS Provider is not needed in the iOS build options anymore because:
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
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.
Other improvements and bug fixes
Android
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 Macnow also includes its' own SDK manager.

We can't respond to all feedback directly, but we do read it all and it very muchhelps 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 developmentthere 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 thestable 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. Ifyou need to reinstall Mono 4.8, you can get ithere.
