Introduction

C# continues to evolve with each new version, bringing exciting features and enhancements to the language. This guide delves into the anticipated updates and features in C# 11 and beyond. It offers insights into the future of the language and includes sample code to illustrate these upcoming enhancements.

Anticipated Features in C# 11

While the specific features of C# 11 are still being developed, some anticipated updates include:

• Record Enhancements: Further improvements to records, possibly adding features like record inheritance and sealed records.
• Pattern Matching Advancements: Enhanced pattern matching capabilities, making it even more powerful and versatile.
• Source Generators: Continued improvements to source generators, with expanded use cases and performance optimizations.
• Nullable Reference Types: Refinements to the nullable reference types system for better safety and clarity in code.

Sample Code

Although C# 11 features are not finalized, here's a glimpse of how some anticipated features might look in code.

C# Code (Record Inheritance - Hypothetical Example):

public record Person(string FirstName, string LastName);
public record Employee(string FirstName, string LastName, string EmployeeId) : Person(FirstName, LastName);
var employee = new Employee("John", "Doe", "E12345");
Console.WriteLine($"Employee: {employee.FirstName} {employee.LastName}, ID: {employee.EmployeeId}");
    

C# Code (Pattern Matching Advancements - Hypothetical Example):

// Hypothetical enhanced pattern matching
if (shape is Circle { Radius: 5 }) 
{
    Console.WriteLine("A small circle");
}
else if (shape is Circle { Radius: 10 }) 
{
    Console.WriteLine("A large circle");
}
else 
{
    Console.WriteLine("Unknown shape");
}
