How to set aspnetcore environment to be considered for publishing an asp net cor


ASP.NET is a popular programming language used for web applications. It provides a powerful framework for building dynamic and interactive websites. One common question that developers often face is how to set the ASP.NET Core environment for an ASP.NET Core application. In this article, we will explore different ways to accomplish this task.

Setting the ASP.NET Core Environment

ASP.NET Core allows you to different environments for your application, such as Development, Staging, and Production. Each environment can have its own configuration , allowing you to customize the behavior of your application based on the environment.

To set the ASP.NET Core environment, you can use the ASPNETCORE_ENVIRONMENT environment . This variable can be set in various ways, depending on your deployment .

Setting the Environment Variable

One way to set the ASPNETCORE_ENVIRONMENT environment variable is by using the command line. Open a command prompt and navigate to the root directory of your ASP.NET Core application. Then, run the following command:


This command sets the ASPNETCORE_ENVIRONMENT environment variable to “Production”. You can replace “Production” with the desired environment name, such as “Development” or “Staging”.

Using Visual Studio

If you are using Visual Studio to develop your ASP.NET Core application, you can set the environment variable through the project properties. Right-click on your project in the Solution Explorer and select “Properties”. In the properties window, navigate to the “Debug” tab. In the “Environment variables” section, add a new variable with the name “ASPNETCORE_ENVIRONMENT” and the desired value.

Accessing the Environment Variable in Code

Once you have set the ASPNETCORE_ENVIRONMENT environment variable, you can access it in your ASP.NET Core application code. The value of the environment variable can be retrieved using the IWebHostEnvironment interface.

public class HomeController : Controller
    private readonly IWebHostEnvironment _environment;

    public HomeController(IWebHostEnvironment environment)
        _environment = environment;

    public  ()
         currentEnvironment = _environment.EnvironmentName;
        // Use the currentEnvironment variable as needed
        return View();

In the above example, the IWebHostEnvironment interface is injected into the HomeController class. The EnvironmentName property of the interface provides the value of the ASPNETCORE_ENVIRONMENT environment variable.


Setting the ASP.NET Core environment is essential for publishing an ASP.NET Core application. By using the ASPNETCORE_ENVIRONMENT environment variable, you can easily configure your application based on the deployment environment. Whether you set the environment variable through the command line or Visual Studio, accessing it in your code allows you to customize the behavior of your application accordingly.
