FluentFtp async methods not workng

Question

I am downloading a file from an ftp usin FLuentFtp. If I call the synchroneous methods:

client.Connect();

var status = client.DownloadFile(localPath, ftpPath);

then it works but the asynchroneous versions namely:

await client.ConnectAsync();

FtpStatus status = client.DownloadFileAsync(localPath, ftpPath).Result;

both don't work. Neither throw an exception but they don't complete within 2 minutes where the synchroneous versions take 2 seconds.

Could it be that there isn't a thread available to run these methods, and if so how can I check this.

The TaskState is WaitingForActivation if that helps narrow things down.

Why don't you await `DownloadFileAsync`? Why do you call `Result` property? — Dennis, Dec 11 '20 at 12:05

I think, you have a deadlock in line:

client.DownloadFileAsync(localPath, ftpPath).Result;

You should call it with await:

FtpStatus status = await client.DownloadFileAsync(localPath, ftpPath);

Ok fair point but it doesn't even reach that line when connect is called asynchroneously. I also disagree that it should deadlock but block the thread I agree with. – G Aker Dec 11 '20 at 11:54
Actually I tried the solution in the question you linked and it fixed my problem. I can't say Ifully understand why but it is now working – G Aker Dec 11 '20 at 12:10
