Dot Net Programming

What is the primary programming language used in .NET development?

• Python

• C#

• JavaScript

• Java

What is the purpose of the Common Language Runtime (CLR) in .NET?

• To brew coffee

• To play music

• To bake cookies

• To provide a runtime environment for managing code execution and system services in .NET applications.

Explain the difference between value types and reference types in .NET.

• Value types store data indirectly, while reference types store data directly.

• Value types and reference types are interchangeable in .NET.

• Value types are mutable, while reference types are immutable.

• Value types store data directly, while reference types store a reference to the data.

What is the role of the Global Assembly Cache (GAC) in .NET?

• It is used to store user-specific configuration settings.

• It stores shared assemblies for use by multiple applications in a versioned and side-by-side manner.

• It acts as a cache for storing temporary data during runtime.

• It provides a backup for system files in case of corruption.

What are the advantages of using ASP.NET for web development?

• ASP.NET offers a robust framework, seamless integration with Microsoft technologies, multi-language support, built-in security features, and easy deployment and maintenance.

• ASP.NET is not user-friendly for beginners

• ASP.NET has limited functionality compared to other frameworks

• ASP.NET does not support cross-platform development

What is the significance of the .NET Framework Class Library (FCL)?

• Developers cannot customize or extend the FCL functionalities

• The FCL is only useful for basic applications

• The FCL is only compatible with specific programming languages

• The .NET Framework Class Library (FCL) is significant as it offers a wide range of pre-built functionalities that developers can leverage to streamline application development.

How does garbage collection work in .NET?

• Garbage collection in .NET is a process where the runtime environment automatically manages memory by identifying and freeing up objects that are no longer in use. It works by periodically scanning the managed heap to find objects that are no longer reachable or referenced by the application.

• Garbage collection in .NET prioritizes memory allocation over deallocation

• Garbage collection in .NET involves manual memory management by the developer

• Garbage collection in .NET only frees up memory when the application is closed

What is the purpose of the using statement in C#?

• To automatically generate unit tests

• To ensure proper disposal of resources

• To enhance runtime performance

• To improve code readability

Explain the concept of inheritance in object-oriented programming with respect to .NET.

• Inheritance in .NET is achieved by copying and pasting code from one class to another

• Inheritance allows a class to inherit only attributes but not methods from another class in .NET

• Inheritance in object-oriented programming allows a new class to be created based on an existing class, inheriting attributes and methods. In .NET, inheritance is implemented using the 'class' keyword followed by the base class name after a colon.

• Inheritance in object-oriented programming is not supported in .NET

What are the different types of authentication supported by ASP.NET?

• Forms authentication, Windows authentication, Passport authentication, None authentication

• Token authentication

• Basic authentication

• Digest authentication
