C# 6.0 Assessment Test

A C# 6.0 Assessment Test evaluates candidates for their proficiency in programming with C# version 6.0, focusing on its new features and improvements over previous versions. C# 6.0 introduced several enhancements aimed at improving developer productivity and code readability, making it crucial for developers to understand and utilize these features effectively.

A C# 6.0 Assessment Test evaluates candidates for:

1. Expression-bodied Members: Mastery of writing concise and readable code for properties, methods, and operators using the new syntax (e.g., int Age => DateTime.Now.Year - BirthYear;).
2. Null-Conditional Operators: Understanding and application of the ?. operator to simplify null checking and avoid NullReferenceExceptions (e.g., var length = person?.Name.Length;).
3. String Interpolation: Skills in using string interpolation ($"" syntax) to embed expressions directly within string literals, enhancing readability and simplifying string formatting (e.g., Console.WriteLine($"Hello, {name}!");).
4. nameof Operator: Knowledge of using the nameof operator to obtain the name of a variable, type, or member as a string constant, enhancing maintainability and avoiding hard-coded strings (e.g., Console.WriteLine(nameof(Person.FirstName));).
5. Auto-Property Initializers: Proficiency in initializing auto-implemented properties directly at declaration time, reducing boilerplate code (e.g., public string Name { get; set; } = "John Doe";).
6. Dictionary Initializers: Skills in using dictionary initializers to initialize dictionaries with key-value pairs using a simpler syntax (e.g., var dict = new Dictionary<int, string> { [1] = "One", [2] = "Two" };).
7. Exception Filters: Understanding and application of exception filters (when clause) to specify conditions under which catch blocks should handle exceptions (e.g., catch (Exception ex) when (ex.InnerException != null)).
8. Static Using Statements (C# 6.0 and later): Familiarity with using static directives to import static members of types into the current namespace, reducing verbosity in code (e.g., using static System.Math;).
9. Await in Catch and Finally Blocks: Ability to use await in catch and finally blocks to asynchronously handle exceptions or perform cleanup tasks (e.g., catch (Exception ex) { await LogAsync(ex); } finally { await CleanupAsync(); }).
10. Compiler Directive Improvements: Knowledge of enhancements in compiler directives (#if, #else, #endif) to include expressions as part of directive conditions (e.g., #if DEBUG && RELEASE).
11. Primary Constructors (C# 6.0 and later): Skills in using primary constructors to declare constructor parameters directly within the class header, simplifying constructor initialization (e.g., public Person(string name, int age) { Name = name; Age = age; }).
12. Overall Application of C# 6.0 Features: Understanding and practical application of these features in real-world scenarios, demonstrating proficiency in leveraging C# 6.0 capabilities to write efficient, maintainable, and modern code.

Overall, our C# 6.0 Assessment Test measures candidates' proficiency in utilizing the latest features of C# 6.0 to enhance productivity, readability, and maintainability of code. It provides valuable insights for hiring managers seeking developers adept at leveraging C# 6.0 features effectively in software development projects.
