What are the best practices for using async in ASP.NET?

When using async in ASP.NET, it's important to follow a few best practices: 1) Use async all the way down, 2) Avoid blocking calls, 3) Use ConfigureAwait(false) when appropriate, and 4) Handle exceptions properly.

Can you explain why I should use ConfigureAwait(false)?

Using ConfigureAwait(false) can improve performance by not capturing the current synchronization context, which is especially useful in library code.

What are the common pitfalls to avoid with async programming?

Common pitfalls include deadlocks, not awaiting tasks, and mixing synchronous and asynchronous code, which can lead to performance issues.

How can I test async methods in my ASP.NET application?

You can test async methods using testing frameworks that support async, like xUnit or NUnit, by marking your test methods as async and using await.
