C# Coding Assessment Test

A C# Coding Assessment Test evaluates candidates for their proficiency in programming with the C# language, assessing their ability to write clean, efficient, and maintainable code. C# is widely used in building desktop applications, web applications, and backend services within the .NET framework, making it essential for developers across various domains.

A C# Coding Assessment Test evaluates candidates for:

1. Syntax and Language Fundamentals: Mastery of C# language syntax, including data types (int, string, float, etc.), variables, operators, control structures (if-else, loops), and methods.
2. Object-Oriented Programming (OOP): Understanding and application of OOP principles such as encapsulation, inheritance, polymorphism, and abstraction. Proficiency in defining and using classes, interfaces, and objects.
3. Collections and Generics: Skills in using built-in collections (lists, dictionaries, queues) and generic types to store and manipulate data efficiently. Understanding of when and how to implement custom generic types.
4. Exception Handling: Knowledge of handling exceptions using try-catch blocks, throwing custom exceptions, and ensuring robust error handling to maintain application stability.
5. LINQ (Language Integrated Query): Proficiency in using LINQ to query and manipulate data from various data sources such as collections, arrays, and databases. Understanding of standard query operators and query syntax.
6. Asynchronous Programming: Ability to write asynchronous code using async and await keywords, managing asynchronous tasks, and understanding the benefits of asynchronous programming in improving application responsiveness.
7. File Handling and IO Operations: Experience in reading from and writing to files using FileStreams, StreamReader, StreamWriter, and handling different file formats and file operations effectively.
8. .NET Framework Libraries: Familiarity with key .NET framework libraries and APIs, such as System.IO, System.Threading, System.Net, and their usage in building scalable and efficient applications.
9. Web Development with ASP.NET Core: Knowledge of building web applications using ASP.NET Core framework, including MVC pattern, routing, middleware, dependency injection, and integrating with front-end technologies like JavaScript and CSS.
10. Database Integration: Skills in integrating C# applications with databases (SQL Server, MySQL, etc.) using Entity Framework Core or ADO.NET. Proficiency in CRUD operations, database migrations, and ensuring data integrity.
11. Testing and Debugging: Ability to write unit tests using frameworks like NUnit or MSTest, conducting unit testing for code coverage, and using debugging tools (e.g., Visual Studio Debugger) to identify and fix bugs.
12. Security Best Practices: Awareness of security vulnerabilities (e.g., SQL injection, cross-site scripting) and implementation of security best practices such as input validation, parameterized queries, and secure data storage.

Overall, our C# Coding Assessment Test measures candidates' proficiency in developing robust and scalable applications using the C# language and .NET framework. It provides valuable insights for hiring managers seeking developers capable of building high-quality software solutions across different domains.
