The Global.asax file in ASP.NET MVC is used as an application-level event handler. It contains various event handlers that can be used to handle application-level events such as application start, end, session start, authentication, and error handling.

Some of the common purposes of the Global.asax file in ASP.NET MVC are:

  1. Application Events: The Global.asax file allows you to handle events like Application_Start, Application_End, Session_Start, Session_End, etc. These events help in managing the lifecycle of the application and performing tasks such as initializing the application, closing the application, initializing session variables, etc.

  2. Routing Configuration: The Global.asax file also allows you to define and configure the routes for your MVC application. It contains the "RegisterRoutes" method where you can define the URL patterns for routing requests to appropriate controllers and actions.

  3. Error Handling: The Global.asax file provides an event called "Application_Error" which can be used to handle any unhandled exceptions that occur in the application. This allows you to customize the error handling and display appropriate error messages to the users.

  4. Authentication and Authorization: The Global.asax file can be used to handle authentication and authorization for the application. It provides events like "Application_AuthenticateRequest" and "Application_AuthorizeRequest" which can be used to implement custom authentication and authorization logic.

Overall, the Global.asax file serves as a central location for managing application-level events and configuring global settings for an ASP.NET MVC application.
