  Program.cs This code is the entry point of an   ASP.NET Core MVC   application. It configures the application pipeline, sets up services, and defines how HTTP requests are handled. Let’s break it down line by line: 1.  public static void Main(string[] args) This is the  entry point  of the application. The  Main  method is called when the application starts. args  is an array of command-line arguments passed to the application. 2.  var builder = WebApplication.CreateBuilder(args); Creates a  WebApplicationBuilder  object, which is used to configure the application. The  args  parameter allows command-line arguments to be passed to the application for configuration. 3.  builder.Services.AddControllersWithViews(); Adds services to the  dependency injection (DI)  container for  MVC controllers and views . This enables the application to use the  Model-View-Controller (MVC)  pattern. 4....

  What is Serialization and Deserialization? Serialization  is the process of converting an object into a format that can be easily stored or transmitted, such as JSON, XML, or binary. This is useful for saving the state of an object to a file, sending it over a network, or storing it in a database. Deserialization  is the reverse process, where the serialized data is converted back into an object. This allows you to reconstruct the object from its serialized form. Why Use Serialization and Deserialization? Persistence : Save the state of an object to a file or database for later use. Communication : Send objects over a network (e.g., in web APIs, microservices). Caching : Store objects in memory or on disk for quick retrieval. Interoperability : Exchange data between different systems or languages using standard formats like JSON or XML. How to Serialize and Deserialize in C# C# provides several ways to serialize and deserialize objects, including: JSON Serialization ...

1. What are Delegates in C#? Explain: Delegates are type-safe function pointers. They act as a placeholder for methods that have a specific signature (return type and parameters). Analogy: Imagine a delegate as a contract. It specifies the "shape" of the method it can hold. Any method that fits that shape (same return type and parameters) can be assigned to the delegate. Example: public delegate int MathOperation(int x, int y);  // Define a delegate // Methods that match the delegate signature public int Add(int x, int y) { return x + y; } public int Subtract(int x, int y) { return x - y; } // Use the delegate MathOperation operation = Add; // Assign the Add method to the delegate int result = operation(5, 3); // Call the method through the delegate 2. What are Events in C#? Explain: Events are a mechanism for broadcasting notifications to interested parties (subscribers). They are built upon delegates. Analogy: Imagine an event as a doorbell. When someone presses the d...
