AddMvcOptions

AddMvcOptions is a method in ASP.NET Core that allows developers to configure various aspects of the Model-View-Controller (MVC) framework. It is typically called within the ConfigureServices method of the Startup class in an ASP.NET Core application.

This method provides access to an IMvcCoreBuilder object, which exposes numerous options for customizing the MVC pipeline. These options include configuring model binding, validation, view engines, formatters, and authorization. For example, developers can use AddMvcOptions to add custom model binders, register custom validation attributes, or configure the order in which view engines are searched.

One common use case for AddMvcOptions is to enable or disable specific features of the MVC framework. For instance, one might use it to disable model validation if it's not required for a particular part of the application. Another use is to integrate third-party libraries or custom components that extend MVC functionality.

The flexibility offered by AddMvcOptions is crucial for tailoring an ASP.NET Core application's MVC behavior to meet specific project requirements. By providing a centralized point for configuration, it helps maintain a clean and organized application structure. Developers can leverage this method to fine-tune their MVC setup without directly modifying the core MVC components.
