Recommended configuration for ASP.NET development using Visual Studio on Linux

Overview:
With the development of open source software and the popularity of Linux operating systems, more and more developers are beginning to ASP.NET development on Linux. As a powerful development tool, Visual Studio has always occupied a dominant position on the Windows platform. This article will introduce how to configure Visual Studio on Linux for ASP.NET development, and provide code examples to help readers better understand.

Configuration steps:

1. Install the Mono runtime environment (Mono Runtime):
   Mono is an open source .NET implementation that can be executed on Linux. NET application. Execute the following command in the command line to install the Mono runtime environment:

   sudo apt-get install mono-complete

   After the installation is complete, you can verify whether the installation is successful by executing the following command in the command line:

   mono --version

2. Download and install Visual Studio for Mac:
   Visual Studio for Mac is a Mac product for Microsoft, but it also runs on Linux. On Mac, you can download the latest version of Visual Studio from the official Visual Studio website and follow the installation wizard to install it.
3. Start Visual Studio for Mac and create an ASP.NET project:
   In the startup interface of Visual Studio for Mac, select "New Project", and then select "ASP.NET Core" in the pop-up dialog box Web Application".

4. Configure project properties:
   In the project property settings, set the target framework to .NET Core and select the runtime environment for Linux.

   <PropertyGroup>
   <TargetFramework>netcoreappx.x</TargetFramework>
   <RuntimeIdentifiers>linux-x64</RuntimeIdentifiers>
   </PropertyGroup>

5. Edit code:
   In Visual Studio for Mac, you can use the built-in code editor to edit ASP.NET applications. In the code editor, you can add controllers, views, and other required code.

Code example:

The following is a simple ASP.NET Core controller example:

using Microsoft.AspNetCore.Mvc;

namespace MyWebApplication.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }
    }
}

The following is a simple ASP.NET Core view example:

@{ 
    ViewData["Title"] = "Home Page";
}

<h1 id="ViewData-Title">@ViewData["Title"]</h1>
<p>Welcome to my home page!</p>

6. Build and run the application:
   In Visual Studio for Mac, click the Build menu and select Build Solution to build your ASP.NET application. Once the build is successful, you can run your application by selecting the Run menu and then selecting Launch.

Summary:
Through the above steps, we can successfully configure Visual Studio for Mac on Linux to achieve ASP.NET development. During this process, we installed the Mono runtime environment, downloaded and installed Visual Studio for Mac, and created an ASP.NET project. We then edited the code in Visual Studio for Mac and demonstrated a simple controller and view example. I hope this article can provide some help and guidance to readers who want to develop ASP.NET on Linux.
