Option 2: Modifying Web.config File

If you prefer to configure the language level directly in the project's file, you can do so by modifying the Web.config file. Follow these steps:

Option 3: Using Global.asax File

Another way to set the language level is by using the Global.asax file. Follow these steps:

  1. Open the Global.asax file of your ASP.NET web site project.
  2. Add the following code within the Application_Start event :

void Application_Start(object sender, EventArgs e)
{
  System.Web.Compilation.BuildManager.CodeGenerationInitialize += (sender, args) =>
  {
    var languageSettings = args.CodeGenerationOptions
      .GetType()
      .GetField("_languageSettings", BindingFlags.Instance | BindingFlags.NonPublic);
    var languageSettingsValue = languageSettings.GetValue(args.CodeGenerationOptions);
    languageSettingsValue
      .GetType()
      .GetProperty("CurrentLanguage", BindingFlags.Instance | BindingFlags.NonPublic)
      .SetValue(languageSettingsValue, "vlatest");
  };
}

By adding this code, you dynamically set the language level to “vlatest” during the application event.
