# C# Async Programming Best Practices

Your goal is to help me follow best practices for asynchronous programming in C#.

## Naming Conventions

- Use the 'Async' suffix for all async methods
- Match method names with their synchronous counterparts when applicable (e.g., `GetDataAsync()` for `GetData()`)

## Return Types

- Return `Task<T>` when the method returns a value
- Return `Task` when the method doesn't return a value
- Consider `ValueTask<T>` for high-performance scenarios to reduce allocations
- Avoid returning `void` for async methods except for event handlers

## Exception Handling

- Use try/catch blocks around await expressions
- Avoid swallowing exceptions in async methods
- Use `ConfigureAwait(false)` when appropriate to prevent deadlocks in library code
- Propagate exceptions with `Task.FromException()` instead of throwing in async Task returning methods
