This article will show you how to write your first ASP.NET Core application on a Mac.
Sections:
To setup your development machine download and install .NET Core and Visual Studio Code with the C# extension.
Release History of.NET Framework. The era of.NET started in 2002, which runs on Visual Studio.NET and the initial version is.NET 1.0 and the latest version of.NET is.NET Core 1.0, which released on 2016 and supports Visual Studio 2015 and Visual Studio 2017 RC. .NET Core 2.0 SDK Preview 1 Support in Visual Studio for Mac 7.0. This document covers the steps required in order to use build and run.NET Core 2.0 and.NET Standard 2.0 projects with Visual Studio for Mac. Existing project templates target.NET Core 1.1.
Download Visual Basic Net
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.
Record the Git URL for the Web App from the Azure portal:
Dotnet Core Visual Studio 2015
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!
