You still need a Mac to deploy an iOS app to the App Store, but there is an awful lot you can do just with Visual Studio on Windows, thanks to a preview tool and a handy cloud service, Matthew Soucoup explained in a presentation at the Visual Studio Live! Conference in Orlando, Fla. Your First ASP.NET Core Application on a Mac Using Visual Studio Code¶ By Daniel Roth, Steve Smith and Rick Anderson. This article will show you how to write your first ASP.NET Core application on a Mac.

This article will show you how to write your first ASP.NET Core application on a Mac.

Visual Studio for Mac provides integrated support for developing and deploying your microservices using Docker containers. Containerize your.NET Core app by adding.

Sections:

To setup your development machine download and install .NET Core and Visual Studio Code with the C# extension.

Follow the instruction in Building Projects with Yeoman to create an ASP.NET Core project.

  • Start Visual Studio Code
  • Tap File > Open and navigate to your Empty ASP.NET Core app

From a Terminal / bash prompt, run dotnetrestore to restore the project’s dependencies. Alternately, you can enter commandshiftp in Visual Studio Code and then type dot as shown:

You can run commands directly from within Visual Studio Code, including dotnetrestore and any tools referenced in the project.json file, as well as custom tasks defined in .vscode/tasks.json.

This empty project template simply displays “Hello World!”. Open Startup.cs in Visual Studio Code to see how this is configured:

If this is your first time using Visual Studio Code (or just Code for short), note that it provides a very streamlined, fast, clean interface for quickly working with files, while still providing tooling to make writing code extremely productive.

In the left navigation bar, there are four icons, representing four viewlets:

  • Explore
  • Search
  • Git
  • Debug

The Explore viewlet allows you to quickly navigate within the folder system, as well as easily see the files you are currently working with. It displays a badge to indicate whether any files have unsaved changes, and new folders and files can easily be created (without having to open a separate dialog window). You can easily Save All from a menu option that appears on mouse over, as well.

The Search viewlet allows you to quickly search within the folder structure, searching filenames as well as contents.

Code will integrate with Git if it is installed on your system. You can easily initialize a new repository, make commits, and push changes from the Git viewlet.

The Debug viewlet supports interactive debugging of applications.

Finally, Code’s editor has a ton of great features. You’ll notice unused using statements are underlined and can be removed automatically by using command. when the lightbulb icon appears. Classes and methods also display how many references there are in the project to them. If you’re coming from Visual Studio, Code includes many of the same keyboard shortcuts, such as commandkc to comment a block of code, and commandku to uncomment.

The sample is configured to use Kestrel for the web server. You can see it configured in the project.json file, where it is specified as a dependency.

  • Run dotnetrun command to launch the app
  • Navigate to localhost:5000:
  • To stop the web server enter Ctrl+C.

Once you’ve developed your application, you can easily use the Git integration built into Visual Studio Code to push updates to production, hosted on Microsoft Azure.

Initialize Git¶

Initialize Git in the folder you’re working in. Tap on the Git viewlet and click the InitializeGitrepository button.

Add a commit message and tap enter or tap the checkmark icon to commit the staged files.

Git is tracking changes, so if you make an update to a file, the Git viewlet will display the files that have changed since your last commit.

Initialize Azure Website¶

You can deploy to Azure Web Apps directly using Git.

  • Create a new Web App in Azure. If you don’t have an Azure account, you can create a free trial.
  • Configure the Web App in Azure to support continuous deployment using Git.

Visual Studio Developing For Mac

Record the Git URL for the Web App from the Azure portal:

Microsoft Visual C++ For Mac

  • In a Terminal window, add a remote named azure with the Git URL you noted previously.

    • gitremoteaddazurehttps://ardalis-git@firstaspnetcoremac.scm.azurewebsites.net:443/firstaspnetcoremac.git

  • Push to master.

    • gitpushazuremaster to deploy.

  • Browse to the newly deployed web app. You should see Helloworld!
