IMvcBuilder

IMvcBuilder is an interface in the ASP.NET MVC framework that represents a builder for configuring an MVC application. It is part of the MVC extensibility model and allows for customization of various aspects of the MVC pipeline. The primary purpose of IMvcBuilder is to provide a fluent API for setting up controllers, views, and other MVC-related services.

When an ASP.NET MVC application is started, an instance of IMvcBuilder is typically created and used to configure the application's services. This configuration can involve registering custom components, setting up routing, and defining how controllers and views are resolved. The builder pattern employed by IMvcBuilder allows developers to chain multiple configuration methods together, making the setup process more readable and organized.

Common uses of IMvcBuilder include adding custom action filters, view engines, model binders, and controller factories. It also plays a role in integrating third-party libraries or custom frameworks that extend MVC functionality. By abstracting the configuration process, IMvcBuilder promotes a cleaner separation of concerns and enhances the maintainability of MVC applications. It is a fundamental building block for advanced MVC customization scenarios.
