Code inspection: Method has async overload with cancellation support

This inspection reports a synchronous call inside an async context when there is an async overload that also accepts a CancellationToken.

This is the stronger version of the async-overload suggestion: the available async API also supports cooperative cancellation, so that token can be propagated.

Example

                using System.Threading;
                using System.Threading.Tasks;

                public class Example
                {
                    public void Load() { }
                    public Task LoadAsync(CancellationToken token) => Task.CompletedTask;

                    public async Task RunAsync(CancellationToken token)
                    {
                        Load();
                    }
                }
            

                using System.Threading;
                using System.Threading.Tasks;

                public class Example
                {
                    public void Load() { }
                    public Task LoadAsync(CancellationToken token) => Task.CompletedTask;

                    public async Task RunAsync(CancellationToken token)
                    {
                        await LoadAsync(token);
                    }
                }
            

Quick-fix

Switch to the async overload, pass an available CancellationToken, and add await.
