How to Add a Global.asax.cs File to Your Visual Studio 2019 Project

If you’re a developer using Visual Studio 2019, you might have encountered the need to add a global.asax.cs file to your project. It’s a file that contains code for the Application_Start event, which happens when the application starts. This file can be used for initializing global variables or setting up application-wide settings.

Step 1: Creating a New Web Application Project

Firstly, you’ll need to create a new ASP.NET web application project in Visual Studio 2019. You can do this by choosing “New Project” from the “File” menu and selecting “ASP.NET Web Application” from the list of templates in the “New Project” dialog box. After entering a project name, location, and other details, click “Create” to make the project.

Step 2: Adding a Global.asax File to the Project

Now, you need to add a global.asax file to the project by right-clicking on the project in the “Solution Explorer” and selecting “Add” > “New Item” from the context menu. In the “Add New Item” dialog, pick “Global Application Class” from the list of templates, name it “Global.asax”, and click the “Add” button. This creates a new file named “Global.asax” in your project.

Step 3: Adding Code to the Global.asax.cs File

After adding the global.asax file to the project, you need to add code to the global.asax.cs file. This file includes the code that executes when the application starts or shuts down. For example:

  
    protected void Application_Start()
      {
        GlobalSettings.Initialize();
      }
  

This initializes global variables. You can also add code to the Application_End method to execute tasks when the application shuts down.

Step 4: Build and Run the Project

Lastly, you can build and run your project to test your code. When the application starts, your code in the Application_Start method will be executed.

Conclusion

Adding a global.asax.cs file to your Visual Studio 2019 project is straightforward, and it can be used for adding code that executes when your application starts or shuts down. By following the steps above, you can add a global.asax.cs file to your project, and you’re ready to start writing your code for important application events.
