# Persist Values With AsyncLocal in C# Async Flow

**[Code Maze](https://daily.dev/sources/codemaze)** · 8 min read · 11 upvotes · 0 comments

## Summary

The AsyncLocal class in C# helps persist values across an async flow, essential for passing data like authenticated user information or logging identifiers through asynchronous .NET applications. By providing a way to store data specific to a single request, AsyncLocal prevents method parameter overload and maintains cleaner code. It involves configuring AsyncLocal fields within the ExecutionContext class, allowing values to be passed and manipulated within an asynchronous flow. However, AsyncLocal is limited to task-level scope and should not be used globally across unrelated asynchronous operations.
