Compile time binding occurs during compilation while runtime binding occurs during execution.

• Compile time binding is also known as early binding, where the method to be called is determined at compile time based on the type of the object.

• Runtime binding is also known as late binding, where the method to be called is determined at runtime based on the actual type of the object.

• Compile time binding is faster as it is done during compilation, while runtime binding is slower as i...read more

Inheritance is a mechanism in OOP where a class inherits properties and behaviors from another class.

• Inheritance allows a class to reuse code from another class.

ASP.NET Page Life Cycle is the series of events that occur from the time a page is requested to the time the page is fully rendered and sent to the client.

• Page Request: When a page is requested by a user, ASP.NET creates an instance of the page class.

• Page Initialization: The page's properties are set and controls on the page are initialized.

• Page Load: The page's controls are loaded with data and events are handled.

• Postback Event Handling: If the page is posted back, the event...read more

Abstract class is a class that cannot be instantiated and may contain abstract methods. Interface is a contract that defines methods that a class must implement.

• Abstract class can have abstract methods as well as concrete methods.

• Interface can only have method signatures, no method bodies.

• A class can implement multiple interfaces but can inherit from only one abstract class.

• Example: Abstract class - Animal with abstract method 'eat'. Interface - IShape with method signatures ...read more

A view is created from a model by using a view engine to render the model data into HTML markup.

• Use a view engine like Razor in ASP.NET to create views from models

• Pass the model data from the controller to the view using ViewBag or strongly-typed models

• Use HTML helpers to display model data in the view

• ViewBag is a dynamic property that allows you to pass data from controller to view.

• ViewData is a dictionary object that allows you to pass data from controller to view.

• TempData is a dictionary object that allows you to pass data from one controller action to another.

Overloading is having multiple methods in the same class with the same name but different parameters. Overriding is implementing a method in a subclass that is already defined in the parent class.

• Overloading allows a class to have multiple methods with the same name but different parameters.

• Overriding is when a subclass provides a specific implementation of a method that is already defined in its parent class.

• Example of overloading: having multiple methods named 'calculate' w...read more

Debugging stored procedures involves using tools like SQL Server Management Studio, setting breakpoints, and analyzing query execution.

• Analyze query execution using tools like SQL Profiler to identify issues

• Use PRINT or SELECT statements to output intermediate results for debugging

• Check for errors in the stored procedure code and fix the...read more

ActionResult and ViewResult are classes in ASP.NET MVC used to return responses to client requests.

• ActionResult is a base class for action results in ASP.NET MVC.

• ViewResult is a type of ActionResult that returns a view to the client.

Common Term Expression is a standardized vocabulary used in healthcare to describe medical concepts.

• Common Term Expression (CTE) is used to ensure consistency and accuracy in medical coding and billing.

• CTE helps healthcare providers communicate effectively with insurance companies and government agencies.

Static keyword is used to declare a member that belongs to the class itself, rather than to instances of the class.

• Static keyword can be applied to variables, methods, properties, and constructors.

• Static members are accessed using the class name, not an instance of the class.

• Static variables retain their values for the entire duration of the program.

• Static methods can be called without creating an instance of the class.

• Example: public static int count = 0; // static variable

Sealed classes are classes that cannot be inherited or used as a base class.

• Sealed classes are used to restrict inheritance for security or optimization reasons.

• They are marked with the 'sealed' keyword.

• Example: 'sealed class MyClass {}'

ViewModel is a class that is responsible for preparing data to be displayed in a view.

• ViewModel separates the logic of data preparation from the view itself.

• It helps in keeping the views lightweight and focused on display.

• ViewModels are commonly used in MVVM (Model-View-ViewModel) architecture.

• Example: In an e-commerce website, a ProductViewModel may contain product details for display.
