According to the Task-based Asynchronous Pattern (TAP), methods returning either a System.Threading.Tasks.Task or a
System.Threading.Tasks.Task<TResult> are considered "asynchronous". Such methods should use the Async suffix.
Conversely methods which do not return such Tasks should not have an "Async" suffix in their names.
Noncompliant code example
using System;
using System.Threading.Tasks;
namespace myLibrary
{
public class Foo
{
public Task Read(byte [] buffer, int offset, int count, // Noncompliant
CancellationToken cancellationToken)
}
}
Compliant solution
using System;
using System.Threading.Tasks;
namespace myLibrary
{
public class Foo
{
public Task ReadAsync(byte [] buffer, int offset, int count, CancellationToken cancellationToken)
}
}
Exceptions
This rule doesn’t raise an issue when the method is an override or part of the implementation of an interface since it can not be renamed.
