How would you explain the concept of CLR in .NET?
Common Language Runtime (CLR) is the runtime environment in the .NET Framework that executes .NET programs. It provides various services such as memory management, exception handling, debugging, security, thread execution, code execution, code safety verification, and compilation.
What are the main differences between ADO.NET and Entity Framework?
ADO.NET is a set of computer software components that programmers can use to access data and data services. It's a part of the base class library that's included with the Microsoft .NET Framework. Entity Framework is an open-source ORM framework for .NET applications supported by Microsoft. It enables developers to work with data as objects, eliminating the need for most data-access code that developers usually need to write.
Describe the difference between early binding and late binding.
Early binding refers to assignment of values to variables during design time, while late binding refers to assignment of values to variables during runtime. Early binding is faster but doesn't allow flexibility like late binding.
How would you handle exceptions in .NET?
Exceptions in .NET are handled using try, catch, and finally blocks. The try block encloses the statements that might throw an exception, whereas the catch block handles an exception if one exists. The finally block is used to execute a given set of statements, whether an exception is thrown or not.
What are generics in .NET?
Generics allow you to delay the specification of the data type of programming elements in a class or a method, until it is actually used in the program. In other words, generics allow you to write a class or method that can work with any data type.

What are the different types of caching in .NET?
There are three types of caching in .NET: Page Caching, Data Caching and Fragment Caching.
Describe the difference between managed and unmanaged code.
Managed code is the code that is written to target the services of the managed runtime environment like Common Language Runtime in .NET. Unmanaged code is the code that is directly executed by the operating system.
How would you ensure the security of your .NET applications?
There are several ways to ensure the security of .NET applications, including using Windows authentication, forms authentication, and authorizing users based on their roles.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with A# .NET version2.3.

What does this simple A# .NET code do?
Console.WriteLine("Hello World!");
This code prints the string 'Hello World!' to the console.
What will be the output of this A# .NET code?
int x = 10;
int y = 20;
int z = x + y;
Console.WriteLine(z);
The output will be 30. The code sums up the values of x and y and stores it in z, then it prints z to the console.
What does this A# .NET code do?
List numbers = new List {1, 2, 3, 4, 5};
numbers.Remove(3);
Console.WriteLine(string.Join(", ", numbers));
This code creates a list of integers, removes the number 3 from the list, and then prints the updated list to the console. The output will be '1, 2, 4, 5'.
What does this A# .NET threading code do?
Thread thread = new Thread(() => {
Console.WriteLine("Hello from the thread");
});
thread.Start();
This code creates a new thread and starts it. The new thread prints 'Hello from the thread' to the console.

It's a design pattern that also separates an application into three components, but it's typically used to simplify event-driven programming for desktop applications.
How would you manage state in a .NET application?
State in a .NET application can be managed in several ways, including using view state, session state, application state, and cookies.
What are the different types of constructors in .NET?
