I suspect that it's using an internal buffer somewhere. Maybe you need to dig into the source to work out whats being held onto.
https://github.com/mono/mono/blob/master/mcs/class/System/System.Net/WebClient.cs But you could use a HttpWebRequest and have a lot more control over it, tho you then need to deal with streams and the like. also, what happens if you move the webclient out to object level, eg: void DoStuff() { WebClient client = new WebClient(); becomes WebClient client; void DoStuff() { client = new WebClient(); and void client_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e) { var webClient = sender as WebClient; webClient.DownloadDataCompleted -= client_DownloadDataCompleted; webClient.DownloadProgressChanged -= client_DownloadProgressChanged; webClient.Dispose(); webClient = null; //added client.Dispose(); client = null; So, the GC can keep easier (maybe better, maybe not :) ) track of it?
