Question

If an API has a synchronous method T DoSomething<T>();, what is the naming convention for the corresponding asynchronous method if it returns Task<T>?

Task<T> DoSomethingTask<T>();    

or

Task<T> DoSomethingAsync<T>();

or something else?

Answer 1

From what I’ve seen in C# 5 / .NET 4.5, the preferred name is DoSomethingTaskAsync or DoSomethingAsync

For example, the WebClient class in .NET 4.5 has methods like DownloadFileTaskAsync, because it already had a method named DownloadFileAsync, so I assume the use of TaskAsync over Async is to maintain backwards compatibility.
