Setting Up Your Development Environment

• Install ASP.NET on your Mac with OS X
• Check which DNX version you have active by running dnvm list

Scaffolding Applications Using Yeoman

Follow the instruction in Building Projects with Yeoman to create an MVC 6 project.

Developing ASP.NET Applications on a Mac With Visual Studio Code

• Start Visual Studio Code

• Tap File > Open and navigate to your ASP.NET app

From a Terminal / bash prompt, run dnu restore to restore the project’s dependencies. Alternately, you can enter command shift p and then type >d as shown:

This will allow you to run commands directly from within Visual Studio Code, including dnx restoreand any commands defined in the project.json file.

At this point, you should be able to host and browse to this simple ASP.NET web application, which we’ll see in a moment.

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. Currently only node.js and mono applications are supported by the interactive debugger.

Finally, Code’s editor has a ton of great features. You should note right away that several using statements are underlined, because Code has determined they are not necessary. Note that 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 keyboard shortcuts you’re used to, such ascommand k c to comment a block of code, and command k u to uncomment.

Running Locally Using Kestrel

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

 }

• Run the dnx web command to launch the app
• Navigate to localhost:5000:

• To stop the web server enter Ctrl+C.

Publishing to Azure

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.
