ACID properties ensure database transactions are processed reliably.

• ACID stands for Atomicity, Consistency, Isolation, and Durability.

• Atomicity ensures that either all operations in a transaction are completed or none are.

• Consistency ensures that the database remains in a valid state before and after the transaction.

• Isolation ensures that multiple transactions can occur concurrently without affecting each other.

• Durabil...read more

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit. Abstraction is the concept of hiding the implementation details and showing only the necessary features of an object.

• Encapsulation helps in data hiding and prevents direct access to data from outside the class.

• Abstraction helps in reducing complexity by hiding unnecessary details and showing only essential features.

• En...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 both abstract and non-abstract methods, while interface can only have abstract methods.

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

• Abstract classes are used when you want to provide a default impleme...read more

Routing is the process of directing network traffic to its destination. Conventional Routing is a method of defining routes based on conventions.

• Routing is the process of determining the path that network packets should take from the source to the destination.

• Conventional Routing involves defining routes based on conventions or predefined rules.

• In web development, routing refers to mapping URLs to specific controllers ...read more

GC stands for Garbage Collection. It is a process of automatically reclaiming memory occupied by objects that are no longer in use.

• GC is a part of the .NET runtime that manages memory by automatically freeing up memory occupied by objects that are no longer needed.

• We can suggest the GC to run by calling the GC.Collect() method, but it is not recommended to force GC as it can have performance implications.

• Forcing GC to ...read more

MasterPage is a feature in ASP.NET that allows for creating a consistent layout for multiple pages.

• MasterPage defines the common structure and interface for all pages in a web application.

• It allows for the separation of content and layout, making it easier to maintain and update.

• MasterPage can contain placeholders for content that can be filled in by individual pages.

• Changes made to the MasterPage will be reflected acr...read more

Error handling in .NET application involves using try-catch blocks to handle exceptions and ensure graceful error recovery.

• Use try-catch blocks to catch exceptions and handle them appropriately

• Use specific exception types for different error scenarios

• Implement logging to track errors and troubleshoot issues

• Consider using global exception handling for unhandled exceptions

• Use custom error messages to provide meaningful f

Code deployment in test environment involves creating a deployment package and deploying it to the test server.

• Create a deployment package containing all necessary files and configurations.

• Deploy the package to the test server using tools like Octopus Deploy or Azure DevOps.

• Test the deployed code in the test environment to ensure it functions as expected.

finally is used in exception handling, final is a keyword for classes, Dispose is used for releasing unmanaged resources.

• finally block is used in exception handling to ensure a piece of code is always executed, whether an exception is thrown or not.

• final keyword is used in C# to prevent inheritance or overriding of a method, class, or property.

• Dispose method is used to release unmanaged resources like file handles or d

Lazy loading is a design pattern where data is loaded only when it is needed.

• Lazy loading helps improve performance by loading data on demand

• It is commonly used in ORM frameworks like Entity Framework

• Example: Loading related entities only when accessed in a database query

SOLID is a set of five design principles in object-oriented programming. One of them is the Single Responsibility Principle (SRP).

• SRP states that a class should have only one reason to change, meaning it should only have one job or responsibility.

• For example, a class that handles both user authentication and database operations violates SRP. It should be split into two separate classes.

• SRP helps in making code more mai

MVC page cycle is the sequence of events that occur during the lifespan of a MVC page.

• MVC page is requested by the user

• Routing engine determines the appropriate controller and action method

• Controller executes the action method and returns a view

• View is rendered and sent back to the user's browser

ASP .Net Page Lifecycle is a series of events that occur when a page is requested, processed, and rendered by the server.

• Page Request: Initiated by the user or browser.

• Page Initialization: Page properties are set.

• Page Load: Controls on the page are loaded and data is bound.

• Postback Event Handling: User interactions trigger events.

• Page Rendering: Page is rendered to HTML and sent to the browser.

• Page Unload: Cleanup and

Sealed classes cannot be inherited from. They are used to prevent inheritance and ensure class integrity.

• Sealed classes are declared using the 'sealed' keyword in C#.

• They are used to prevent other classes from inheriting from them.

• Sealed classes can inherit from other classes, but they cannot be inherited from.

Global tables are accessible to all sessions, while temp tables are only accessible to the session that created them.

• Global tables are permanent and stored in the database, while temp tables are temporary and stored in memory or tempdb.

• Global tables can be accessed by multiple users and sessions, while temp tables are local to the session that created them.

• Global tables require explicit creation and dropping, while tem...read more

The var keyword is not used in SQL, it is used in C# to declare implicitly typed variables.

• The var keyword in C# allows you to declare a variable without explicitly specifying the type, the type is inferred by the compiler.

• In SQL, you must explicitly specify the data type when declaring variables or columns.

• Example in C#: var number = 10; // Compiler infers that number is an integer

• Example in SQL: DECLARE @name VARCHAR
