Mobirise is a downloadable offline web builder that is supported on Win, Mac and Android Operating System. It's a very good benefit just in case you wish or have to. The ArcGIS Web AppBuilder download package contains the Windows version of Node.js. If you are on a Windows platform, proceed to the next section to start Web AppBuilder. If you are on a platform other than Windows, such as Mac or Linux, you need to install Node.js independently on your platform first. If you already have Node.js installed.
Visual Studio for Mac makes it easy to develop your app's service with its support for the latest ASP.NET Core Web development platform. ASP.NET Core runs on .NET Core, the latest evolution of the .NET Framework and runtime. It's been tuned for fast performance, factored for small install sizes, and reimagined to run on Linux and macOS, as well as Windows.
Installing .NET Core
.NET Core 3.1 is automatically installed when you install Visual Studio for Mac. For more information about versions of .NET Core supported in Visual Studio for Mac see .NET Core Support.
Creating an ASP.NET Core app in Visual Studio for Mac
Open Visual Studio for Mac. On the Start Screen, select New Project...
This will display the New Project dialog, allowing you to select a template to create your application.
There are a number of projects that will provide you with a pre-built template to start building your ASP.NET Core Application. These are:
Select the ASP.NET Core Empty Web Application and press Next. Give the Project a Name and press Create. This creates a new ASP.NET Core app. In the solution pad's left pane, expand the second arrow and then select Startup.cs. It should look similar to the image below:
The ASP.NET Core Empty template creates a web application with two default files: Program.cs and Startup.cs, which are explained below. It also creates a Dependencies folder, which contains your project's NuGet package dependencies such as ASP.NET Core, the .NET Core framework, and the MSBuild targets that build the project:
Program.cs
Open and inspect the Program.cs file in your project. Notice that several things are happening in the
Main method – the entry into your app:

An ASP.NET Core app creates a web server in its main method by configuring and launching a host via an instance of
WebHostBuilder . This builder provides methods to allow the host to be configured. In the template app the following configurations are used:
However, you can also add additional configurations, such as:
Startup.cs
The Startup class for your app is specified in the
UseStartup() method on the CreateWebHostBuilder . It is in this class that you will specify the request handling pipeline, and where you configure any services.
Open and inspect the Startup.cs file in your project:
This Startup class must always adhere to the following rules:
The
ConfigureServices method defines the services that will be used by your app.
The
Configure allows you to compose your request pipeline using Middleware. These are components used within an ASP.NET application pipeline to handle requests and responses. The HTTP pipeline consists of a number of request delegates, called in sequence. Each delegate can choose to either handle the request itself, or pass it to the next delegate.
You can configure delegates by using the
Run ,Map , and Use methods on IApplicationBuilder , but the Run method will never call a next delegate and should always be used at the end of your pipeline.
The
Configure method of the pre-built template is built to do a few things. First, it configures an exception handling page for use during development. Then, it sends a response to the requesting web page with a simple 'Hello World'.
This simple Hello, World project can run now without any additional code being added. To run the app, you can either select which browser you want to run app the app in using the dropdown right of the Play button, or simply hit the Play (triangular) button to use your default browser:
Visual Studio for Mac uses a random port to launch your web project. To find out what port this is, open the Application Output, which is listed under View > Pads. You should find output similar to that shown below:
Once the project is running, your default web browser should launch and connect to the URL listed in the Application Output. Alternatively, you can open any browser of your choice, and enter
http://localhost:5000/ , replacing the 5000 with the port that Visual Studio output in the Application Output. You should see the text Hello World! :
Adding a Controller
ASP.NET Core Apps use the Model-View-Controller (MVC) design pattern to provide a logical separation of responsibilities for each part of the app. MVC consists of the following:
For more information on using MVC refer to Overview of ASP.NET Core MVC guide.
To add a controller, do the following:

If you need to install .NET Core manually on Mac OS 10.12 (Sierra) and higher, do the following:
Make sure to complete all steps successfully to ensure that .NET Core is installed successfully.
