"Check for updates" fails behind a web proxy about ilspy HOT 14 CLOSED

Which ILSpy version are you using?
The current versions (starting with build 0.1.0.406) should work fine behind a proxy.

Please reopen if this issue occurs again (in 1.0.0.824 or later). I've never used the .NET proxy stuff before, so I don't exactly know what I'm doing here ;)

Reopen issue - note that I am using a proxy script not just a proxy server.
It should be working in .NET 2.0+ though
http://msdn.microsoft.com/en-us/magazine/cc300743.aspx#S3

from ilspy.

I cannot reproduce this problem. I tried both a manually configured proxy and using a configuration script; and ILSpy correctly uses the proxy in both cases.

from ilspy.

I still get the same error (I'm using version 1.0.0.826 with debugger) also checked with binary version 1.0.0.943 and same error.

When I set the proxy manually it works.
Note that my proxy settings are:

Use configuration script checkbox is checked and the address has a URL to the proxy script in it (not just a direct link to proxy server):

http://intranetserver/proxy/proxy.pac

The actual proxy is another server.

static Task GetLatestVersionAsync()
{
var tcs = new TaskCompletionSource();
WebClient wc = new WebClient();
wc.UseDefaultCredentials = true;
wc.Proxy = new WebProxy
{
UseDefaultCredentials = true,
Address = new Uri("http://my-proxy:80")
};
wc.DownloadDataCompleted += delegate(object sender, DownloadDataCompletedEventArgs e) {
if (e.Error != null) {
tcs.SetException(e.Error);
} else {
try {
XDocument doc = XDocument.Load(new MemoryStream(e.Result));
var bands = doc.Root.Elements("band");
var currentBand = bands.FirstOrDefault(b => (string)b.Attribute("id") == "stable") ?? bands.First();
Version version = new Version((string)currentBand.Element("latestVersion"));
string url = (string)currentBand.Element("downloadUrl");
if (!(url.StartsWith("http://", StringComparison.Ordinal) || url.StartsWith("https://", StringComparison.Ordinal)))
url = null; // don't accept non-urls
latestAvailableVersion = new AvailableVersionInfo { Version = version, DownloadUrl = url };
tcs.SetResult(latestAvailableVersion);
} catch (Exception ex) {
tcs.SetException(ex);
}
}
};
wc.DownloadDataAsync(UpdateUrl);
return tcs.Task;
}

Won't fix for 1.0; simply because I can't reproduce this on my machine.
I'm happy to hear about any ideas on how to fix this.

Can you try this again with version 2.0.0.1370?
I hope this time it'll work correctly with proxies requiring authentication. I tested it without proxy and with a proxy configuration script (but my proxy server doesn't require authentication).

from ilspy.

2.0.0.1370 works fine. :)

Version 1.0.0.1000 gives the following stack trace behind Microsoft ISA Server (authenticated proxy)

Placing the following text in a file called ILSpy.exe.config alongside ILSpy.exe fixes the issue:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.net>
    <defaultProxy useDefaultCredentials="true" />
  </system.net>
</configuration>

from ilspy.

Fixed in the 2.0.0.1525 nightly without the workaround above.
