What is an Action Method?

An action method is a method in a controller class with the following restrictions:

  • It must be public. Private or protected methods are not allowed.
  • It cannot be overloaded.
  • It cannot be a static method.
  • An action method executes an action in response to an HTTP request.

    For example, here is an example of an Index() action method on the PostController. It takes an id as an input and returns an IActionResult, which can be implemented by any result classes (see the following question).

    What is NuGet package manager?

    Software developers don’t write all code from scratch. They rely on libraries of code written by other developers. Any modern development platform must provide a mechanism where developers can download and use existing libraries, often called packages. For example, the JavaScript ecosystem has NPM (Node Package Manager), where developers can find and use libraries written by other JavaScript developers.

    NuGet is a package manager for the .NET ecosystem. Microsoft developed it to provide access to thousands of packages written by .NET developers. You can also use it to share the code you wrote with others.

    A typical web application developed using ASP.NET relies on many open source NuGet packages to function. For example, Newtonsoft.Json is a very popular package (with 91,528,205 downloads at the time of writing) used to work with JSON data in .NET.

    1 What is the difference between Stack and Heap?

    Ans: The stack is used for static memory allocation and access to this memory is fast and simple to keep track of. Heap is used for dynamic memory allocation and memory allocation to variables that happen at run time. Accessing the heap memory is complex and slower compared to the stack.

    1 What is the purpose of the Startup class?

    This class handles two important aspects of your application, namely service registration, and middleware pipeline.

    Services are C# classes that your application depends on for providing additional functionality, both used by the framework and your application. Examples include logging, database, etc. These services must be registered to be instantiated when your app is running and when it needs them.

    The middleware pipeline is the sequence in which your application processes an HTTP request (the next question explains the concept of Middleware in detail).

    Startup class contains two methods: ConfigureServices() and Configure(). As the name suggests, the first method registers all the services that the application needs. The second method configures the middleware pipeline.
