Introducing C# 12: Exploring the Latest Features

Hey there, tech enthusiasts! Today, we will dive into the exciting world of C# 12 and explore some of its latest features. C# 12 comes packed with innovative enhancements that will make your coding experience even more enjoyable. Let’s take a closer look!

Pattern Matching Enhancements

C# 12 introduces several pattern matching enhancements that simplify the way we write code and handle conditional expressions.

var result = obj is Person { Age: var age };

In the example above, C# 12 allows us to extract property values from a pattern match using the var keyword and simplified syntax. This makes our code more concise and readable.

Record Structs

Another exciting addition in C# 12 is the introduction of record structs. These lightweight structures combine the immutability and value semantics of structs with the convenience of record classes.

public record struct Point(int X, int Y);

With record structs, we can easily create immutable value types that are efficient and provide expressive APIs.

Async Streams

C# 12 introduces async streams, making it easier to work with asynchronous data streams. Now, we can use the await foreach loop to iterate asynchronously over data streams.

await foreach (var item in GetDataStreamAsync())
    // Process the item asynchronously

Isn’t that cool? With async streams, we can handle asynchronous data streams in a more elegant and efficient manner.


C# 12 brings a range of exciting features to the table, making it a fantastic language for building modern and efficient applications. In this post, we explored just a few of the many enhancements C# 12 has to offer.

Stay tuned for more updates and happy coding!
