Labeled break and continue statements in C# 15

C# 15 introduces labeled break and continue statements, allowing developers to exit or continue an outer loop from within a nested loop by referencing a label on the outer loop. This provides a clearer, more readable alternative to using goto statements or boolean flag variables, which were previously the only ways to achieve this behavior. The feature is currently in preview with .NET 11 preview 7 and requires setting LangVersion to preview. The author provides code examples comparing the new labeled syntax against goto-based and flag-based approaches, and shares a sample GitHub repository with tests. The feature could still change before the final C# 15 release, and the author expects it to be used sparingly, similar to goto statements, but valuable in the specific nested-loop scenarios it addresses.
