Xamarin App Development with Visual Studio| Visual Studio 2018-11-01T14:58:51+00:00 Visual Studio Tools for Xamarin Deliver native Android, iOS, and Windows apps with a single shared.NET code base.
You can use Visual C++ for Cross-Platform Mobile Development to edit, debug and deploy iOS code to the iOS Simulator or to an iOS device, but because of licensing restrictions, the code must be built and run remotely on a Mac. To build and run iOS apps using Visual Studio, you need to set up and configure the remote agent, vcremote, on your Mac. The remote agent handles build requests from Visual Studio and runs the app on an iOS device connected to the Mac, or in the iOS Simulator on the Mac.
Note
For information on using cloud-hosted Mac services instead of a Mac, see Configure Visual Studio to connect to your cloud hosted Mac. The instructions are for building using Visual Studio Tools for Apache Cordova. To use the instructions to build using C++, substitute vcremote for remotebuild.

Once you have installed the tools to build using iOS, refer to this topic for ways to quickly configure and update the remote agent for iOS development in Visual Studio and on your Mac.
Prerequisites
To install and use the remote agent to develop code for iOS, you must first have these prerequisites:
Install the remote agent for iOS
When you install Visual C++ for Cross-Platform Mobile Development, Visual Studio can communicate with vcremote, a remote agent running on your Mac to transfer files, build and run your iOS app, and send debugging commands.
Before you install the remote agent, make sure you have satisfied the Prerequisites and installed Visual C++ for cross-platform mobile development.
To download and install the remote agent
If you update to a new version of Visual Studio, you must update to the current version of the remote agent as well. To update the remote agent, repeat the steps to download and install the remote agent.
Start the remote agent
The remote agent must be running for Visual Studio to build and run your iOS code. Visual Studio must be paired with the remote agent before it can communicate. By default, the remote agent runs in secured connection mode, which requires a PIN to pair with Visual Studio.
To start the remote agent
The first time you start the agent, and any time you create a new client certificate, you are provided with the required information to configure the agent in Visual Studio, including the host name, the port, and the PIN.
If you intend to configure the remote agent in Visual Studio using the host name, ping the Mac from Windows using the host name to verify that it is reachable. Otherwise, you may need to use the IP address instead.
The generated PIN is for one time use, and is only valid for a limited time. If you do not pair Visual Studio with the remote agent before the time expires, you will need to generate a new PIN. For more information, see Generate a new security PIN.
You can use the remote agent in unsecured mode. In unsecured mode, the remote agent can be paired to Visual Studio without a PIN.

To enable secured connection mode
Once you have started the remote agent, you can use it from Visual Studio until you stop it.
To stop the remote agent
Configure the remote agent in Visual Studio
To connect to the remote agent from Visual Studio, you must specify the remote configuration in the Visual Studio options.

Visual Studio uses the same information to connect to the remote agent on your Mac each time you use it. You do not need to pair Visual Studio with the remote agent again unless you generate a new security certificate on your Mac, or its hostname or IP address changes.
Generate a new security PIN
When you start the remote agent the first time, the generated PIN is valid for a limited amount of time—by default, 10 minutes. If you don't pair Visual Studio to the remote agent before the time expires, you will need to generate a new PIN.
To generate a new PIN
Generate a new server certificate
For security purposes, the server certificates that pair Visual Studio with the remote agent are tied to the IP address or host name of your Mac. If these values change, you must generate a new server certificate, and then reconfigure Visual Studio with the new values.
To generate a new server certificate
Configure the remote agent on the Mac
You can configure the remote agent using various command line options. For example, you can specify the port to listen for build requests and specify the maximum number of builds to maintain on the file system. By default, the limit is 10 builds. The remote agent will remove builds that exceed the maximum on shutdown.
To configure the remote agent
Troubleshoot the remote agentDebugging on an iOS device
If debugging on an iOS device does not work, there could be issues with the tool ideviceinstaller, which is used to communicate with an iOS device. This tool is typically installed from Homebrew during the installation of vcremote. Follow the steps below as a workaround.
Open the Terminal app and update ideviceinstaller and its dependencies by running the following in order:
Verify that ideviceinstaller can communicate with the device by trying to list the apps installed on the device:
ideviceinstaller -l
If ideviceinstaller errors that it cannot access the folder
/var/db/lockdown , change the privilege on the folder with:
sudo chmod 777 /var/db/lockdown
Then verify again if ideviceinstaller can communicate with the device.

After spending months in preview, Microsoft today is officially launching its Visual Studio coding platform for the Mac (via VentureBeat). Visual Studio allows developers to code applications using Microsoft's integrated development environment (IDE) on Apple's macOS platform, which they can sync across both Windows and Mac devices.
Thanks to integration with Xamarin, a cross-platform software development company that Microsoft acquired last year, Visual Studio encourages macOS and iOS developers 'to use Microsoft’s development tools, since they will no longer need a Windows computer or virtual machine to do so.' Xamarin Studio is expected to eventually close for good following a full integration into Microsoft. “Developers get a great IDE and a single environment to not only work on end-to-end solutions — from mobile and web apps to games — but also to integrate with and deploy to Azure,” Scott Guthrie, executive vice president of the Microsoft Cloud and Enterprise group, said in a statement. “Whether you use C#, F#, .NET Core, ASP.NET Core, Xamarin or Unity, you’ll get a best-in-class development environment, natively designed for the Mac.”Visual Studio has been designed natively for macOS, according to Microsoft, letting developers manage their code hosted by any provider, including GitHub and Visual Studio Team Services. Developers can build, connect, and tune native mobile apps for iOS, macOS, and Android while also having the ability to create web applications thanks to support for ASP.NET Core. In terms of programming languages, the C# and F# languages are supported. There are three different versions of Visual Studio for Mac that users can download, including Visual Studio Community, Visual Studio Professional, and Visual Studio Enterprise. Microsoft markets Community as its free, but 'fully-featured,' IDE for students and individual developers. Professional targets small teams with subscription benefits, while more 'demanding' users and projects with larger scale are suggested to look into Enterprise. For its cloud subscriptions, there are yearly and monthly options available to users interested in the higher-tier Visual Studio plans. An annual subscription to Visual Studio Professional costs $539/year while a monthly subscription costs $45/month. For Visual Studio Enterprise, users will pay $2,999/year or $250/month. Subscribers will be able to earn small credits back each month for the yearly tiers, contingent on their use of different Azure services. For a detailed breakdown of the differences between each Visual Studio subscription, including individual licenses, check out the app's new website.
