How can I use NSubstitute for asynchronous methods?
An example of an AI chatbot conversation about NSubstitute's support for async methods.

What if I want to throw an exception from an async method?
You can use Returns(Task.FromException<YourType>(new Exception("Your message"))); to simulate an exception being thrown.
Can I verify that an async method was called?
Yes, you can use Received().SomeAsyncMethod() to verify that the async method was called.
Are there any specific versions of NSubstitute I need for async support?
Async support has been available since NSubstitute 2.0, so make sure you're using that version or later.
