OutputCache label has a “Location” attribute and it is fully controllable. Its default value is “Any”, however, there are the following locations available; as of now, we can use anyone. The Razor View Engine prevents Cross-Site Scripting attacks by encoding the script or HTML tags before rendering to the view.

  • This also acts like as Response.Redirect() in ASP.NET WebForm.
  • While a Function is compiled and executed when it is called for.

  • Updating an Empty table using joins does not sound right to me.
  • ASP.NET MVC is open-source software that implements the model-view-controller pattern in developing user interfaces, making it critical to other areas of development.

Two classes B and C inherit from A, and D inherits from both B and C but doesn’t override the method defined in A. The Diamond Problem arises when class B or C has overridden the method differently and D cannot decide to inherit from either B or C. No, .NET supports only single inheritance due to the diamond problem. Also, it would add complexity when used in different languages. Shadowing is how to become a .net mvc developer used to provide a new implementation for the base class method and helps protect against subsequent base class modification. Overriding allows you to rewrite a base class function with a different definition and achieve polymorphism. Method Overriding is a process that allows using the same name, return type, argument, and invoking the same functions from another class in the derived class.

It may require checking for a provided implementation throughout the class . Dependency Injection is done by supplying the DEPENDENCY through the class’s constructor when instantiating that class. Injected component can be used anywhere within the class. Should be used when the injected dependency is required for the class to function.
