It creates the user interface with data from the model with which the end-user can interact. An example would be an edit view of a product table that displays text boxes, dropdown lists, and checkboxes based on the current state of a Product object. “ViewBag” and “ViewData” are special methods used to pass data from controllers to views in .NET MVC apps. By design, “ViewBag” uses dynamic properties, while ViewData utilizes a dictionary-like object.
Implement InvokeAsync() method with the required logic to retrieve cart data and calculate totals. In the shared layout or specific views, call the view component using @await Component.InvokeAsync(“ShoppingCartSummary”). Razor Pages still adhere to the separation of concerns principle, as they separate UI markup (HTML) from server-side C# code using the “@” symbol.
Define POST and GET action types.
Initially, the ASP.NET MVC framework comes with one view engine i.e. web forms (ASPX) view engine and from the ASP.NET MVC3 framework a new view engine i.e. Now, it is also possible to use other third-party view engines such as Spark, NHaml, etc. This is very helpful in a large web application, where all the controllers, views, and models have a single set of folders and that becomes difficult to manage. This is the most customizable and extensible platform or framework provided by Microsoft.
The two execution steps involve understanding the request and, secondly, sending out the most appropriate response based on the type of request.

In this book, we have shared a few angular coding questions that I came across recently.

It is the one that will interact with both the models and views to control the flow of application execution. Based on the user actions, the respective controller works with the model and view and sends responses back to the user. The view is the component in the MVC design pattern which represents the user interface with which the end-user can interact.
