C# 12 is the latest version of the C# programming language that is closely associated with .NET Core technology. It brings several new features and enhancements aimed at improving developer productivity and code quality. One of the notable features in C# 12 is the introduction of "Parameter null checking" with the introduction of "notnull" and "nonnull" attributes. This allows developers to more accurately define the intent of parameters, helping to prevent null reference exceptions. Additionally, C# 12 brings the "record structs" feature. This allows for the creation of lightweight, immutable data types that are similar to records but with value type semantics. Furthermore, C# 12 introduces "field and property initializers for structs" which allows initialization of fields and properties directly within the struct definition. This makes the initialization of structs more concise and readable. Here's an example of how the "notnull" attribute can be used in C# 12: public void ProcessData([notnull] string input) { // Implementation } This code snippet demonstrates the use of the "notnull" attribute to specify that the "input" parameter cannot be null. This helps to enforce stricter null checking at compile-time. As for "record structs," consider the following example: public record struct Person { public string Name { get; init; } public int Age { get; init; } } In this example, the "record struct" is used to define a lightweight immutable data type, utilizing the "init" accessor for properties to support immutability. These are just a few highlights of the new features introduced in C# 12 within the .NET Core technology ecosystem, showcasing the language's ongoing evolution to facilitate efficient and robust software development. Please let me know if you need further details or specific examples related to C# 12 within the context of .NET Core.
