Unreachable code detected

Nullability of reference types in return type of 'Task<(bool?, IDownloadState?)> VerificationCache.Get(IDownloadState archive)' doesn't match implicitly implemented member 'Task<(bool? IsValid, IDownloadState State)> IVerificationCache.Get(IDownloadState archive)'.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
