That is odd, I can't really make it more of a test case because that's all
there is. If I start a clean solution and a console project with just
class MainClass
{
public static void Main (string[] args)
{
string file =
"http://www.kernel.org/pub/linux/kernel/v2.0/linux-2.0.1.tar.bz2";;
System.Net.WebClient client = new
System.Net.WebClient();
client.DownloadDataAsync(new System.Uri(file));
client.CancelAsync(); // still kabooms
}
}
I get the same crash. Are we using the same version? I'm on 2.10.9 (Stable)
and I'm not really in a position where I'd feel comfortable switching to the
beta branch... but if it works on beta and not stable then I guess I can
just wait for it to be fixed, the project I'm working on isn't due for
release for quite a while :-)
