1. Open the terminal and navigate to the root of your application built in the previous recipe.
2. The directory structure should look like this:

3. Now type the following command and press Enter in the terminal to create the new ASP.NET Core MVC application:

      $ dotnet new mvc -o Chapter3.LogFile.LogAppMvc

4. Let's add this new project to the solution:

      $ dotnet sln add 
      Chapter3.LogFile.LogAppMvc/Chapter3.LogFile.LogAppMvc.csproj

5. Now let's perform a build to check that everything is working fine:

      $ dotnet build

6. Now, navigate to the app we just created:

      $ cd Chapter3.LogFile.LogAppMvc/

7. Execute the application with the following command:

      $ dotnet run

8. If everything is fine, open your browser and type http://localhost:5000 in the address bar and hit Enter. The browser output should look like this:

9. Let's close the browser and, in the terminal window, hit Ctrl + C to stop the web server.
10. We need to add the reference to our .NET Standard 2.0 library we built before. Let's add it now using this command in the terminal:

      $ dotnet add reference 
      ../Chapter3.LogFile.LogLib/Chapter3.LogFile.LogLib.csproj 

11. Let's get back to the root folder by typing the following command:

      $ cd ..

12. Now, in the root of the solution directory, type the following command to open Visual Studio Code using the current directory:

      $ code . 

13. In Visual Studio Code, expand the Chapter3 label and expand Chapter3.LogFile.LogAppMvc.
14. Again, expand the Controllers folder and click on HomeController.cs:
    

15. In HomeController.cs, add the following using directive to the last line of the using directives block:

      using Chapter3.LogFile.LogLib;

16. Now, next to the starting curly bracket of the Index method of the HomeController class, add the following code:

      TextLog logFile = new TextLog();
      logFile.WriteLog("You are in the Index action.");
      logFile.CloseLog();

17. Let's add more code inside the About method too:

      TextLog logFile = new TextLog();
      logFile.WriteLog("You are in the About action.");
      logFile.CloseLog();

18. Do the same to the Contact method as well:

      TextLog logFile = new TextLog();
      logFile.WriteLog("You are in the Contact action.");
      logFile.CloseLog();

19. Now we are done with adding code, let's navigate to Chapter3.LogFile.LogAppMvc:

      $ cd Chapter3.LogFile.LogAppMvc/

20. Let's run the application:

      $ dotnet run

21. Open your favorite browser, type localhost:5000 in the address bar, and press Enter. Click on the navigation links for Home, About, and Contact a few times.
22. Close the browser.

23. Now go to Visual Studio Code, expand the Chapter3 label, and expand Chapter3.LogFile.LogAppMvc. You should see a file named server_log.txt in the root:

24. Now click on the server_log.txt filename to see the output:
