Exception filters run when some of the exceptions are unhandled and thrown from an invoked action. The reason for the exception can be anything and so is the source of the exception. Next, we simply need to update the HandleErrorAttribute on the action method.
- Remote validation is the process where we validate specific data posting data to a server without posting the entire form data to the server.
- ViewData is a more traditional approach to passing data between a Controller and a View, and is useful for passing larger amounts of data.
- To intercept exceptions globally, the filter should be registered in GlobalFilterCollection (usually in ~/App_Start/FilterConfig).
- You can use it to create queries in standard languages that are later converted into the appropriate query language of the data source you are accessing in your application.
- BeforeFilter() is called before the action is executed and can be used to perform tasks such as authentication or authorization checks.
- Bundling and minification combine and compress multiple JS and CSS files into a single “minified” file.
- Entity Framework is one such essential tool, as it simplifies data access and provides an efficient way to interact with databases.

Explain what is routing in MVC? What are the three segments for routing important?
In ASP.NET MVC there are three ways – ViewData, ViewBag, and TempData to pass data from the controller to view and in the next request. Like WebForm, we can also use Session to persist data during a user session. That means once an action method becomes a child action, then it will not respond to the URL requests rather it will be invoked by other action methods of your application. In the ASP.NET MVC application when the client makes a request (i.e. HTTP Request) for a resource from the browser then that request is first Received by the Routing Engine.

Describe the Role of Models In .NET MVC And How They Interact with Views and Controllers.
ActionResult allows various types of results (e.g., ViewResult, JsonResult), providing flexibility in responding to different client requests. ASP.NET MVC also supports attribute-based routing, where developers can define custom routes directly on controllers or actions using Route attributes. This allows more flexibility and better organization of routing rules. The MVC Model contains all application logic (business logic, validation logic, and data access logic), except pure view and controller logic.
