First 20 minutes

General A# .NET version3.1 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in A# .NET version3.1 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you describe the role of the Common Language Runtime (CLR) in .NET?

CLR is a major component of .NET framework. It manages the execution of .NET programs and provides services like memory management, garbage collection, security, and exception handling.

What are the different types of assemblies in .NET?

There are two types of assemblies in .NET - Private assemblies and Shared assemblies. Private assemblies are used by a single application, while Shared assemblies can be used by multiple applications.

Describe the difference between managed and unmanaged code in .NET.

Managed code is executed by the CLR, providing services such as garbage collection, exception handling, and security. Unmanaged code is executed directly by the operating system, outside the CLR environment.

How would you handle exceptions in .NET?

In .NET, exceptions can be handled using try, catch, finally and throw keywords. Try block contains the code which might throw an exception, catch block handles the exception if one occurs, finally block contains the cleanup code which is always executed, and throw keyword is used to throw an exception explicitly.

What are the different types of collections in .NET?

There are four types of collections in .NET - List, Stack, Queue, and Dictionary. List is an ordered collection of items, Stack is a LIFO collection, Queue is a FIFO collection, and Dictionary is a collection of key-value pairs.

Next 20 minutes

Specific A# .NET version3.1 development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

Describe the difference between early binding and late binding in .NET.

In early binding, the method to call is determined at compile time. In late binding, the method to call is determined at runtime. Early binding is faster and safer as compared to late binding.

How would you implement multithreading in .NET?

.NET provides System.Threading namespace for working with threads. We can create a new thread by creating an instance of Thread class and calling its Start method. We can also use ThreadPool class to use a pool of worker threads.

What are the different ways of deploying a .NET application?

There are three ways to deploy a .NET application - XCOPY deployment, ClickOnce deployment, and creating a setup project. XCOPY deployment involves copying the application files to the target machine, ClickOnce deployment allows you to deploy the application via web, and setup project allows you to create a Windows Installer package.

Describe the difference between a Value Type and a Reference Type.

Value types are stored in the stack and contain the actual data. Reference types are stored in the heap and contain a reference to the actual data. Value types have a default value and can never be null, while reference types can be null.

How would you implement inheritance in .NET?

Inheritance in .NET is implemented using ':' operator. The class which is being inherited is called base class and the class which inherits is called derived class. The derived class can access all the public and protected members of the base class.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with A# .NET version3.1.

What does the following code do?
Console.WriteLine("Hello, World!");
This code prints the string 'Hello, World!' to the console.
What does the following code do?
var numbers = new List {1, 2, 3, 4, 5};
numbers.ForEach(Console.WriteLine);
This code creates a list of integers and then uses the ForEach method to iterate over each element in the list, printing each one to the console.
What does the following code do?
var numbers = new List {1, 2, 3, 4, 5};
var evenNumbers = numbers.Where(n => n % 2 == 0);
This code creates a list of integers and then uses the Where method to filter out the even numbers, creating a new enumerable of just the even numbers.
What does the following code do?
var task = Task.Run(() => {
  Console.WriteLine("Hello from a task");
});
task.Wait();
This code creates a new task that prints 'Hello from a task' to the console. The Wait method is then called to block the current thread until the task completes execution.

Wrap-up questions

Final candidate for A# .NET version3.1 Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle A# .NET version3.1 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of delegates in .NET?

There are three types of delegates in .NET - Singlecast delegate, Multicast delegate, and Generic delegate. Singlecast delegate points to a single method, Multicast delegate points to multiple methods, and Generic delegate is a type-safe delegate which can point to any method having the same signature.

Describe the difference between Dispose and Finalize methods in .NET.

Dispose method is used to free unmanaged resources like files, database connections, etc. at any time. Finalize method is used to free unmanaged resources but it is called by the Garbage Collector before the object is collected.

How would you use LINQ in .NET?

LINQ (Language Integrated Query) is used to query data from different data sources like collections, databases, XML, etc. in a consistent manner. We can use LINQ operators or query syntax to write LINQ queries.
