Question

Calling a WCF Service in my application throws EndpointNotFoundException after one minute. All timeouts are more than one minute.

var binding = new BasicHttpBinding {
    OpenTimeout = TimeSpan.FromMinutes(3),
    CloseTimeout = TimeSpan.FromMinutes(6),
    ReceiveTimeout = TimeSpan.FromMinutes(2),
    SendTimeout = TimeSpan.FromMinutes(5)
};
client = new ServiceClient(binding, new EndpointAddress("http://..."));
client.InnerChannel.OperationTimeout = TimeSpan.FromMinutes(4);

I found a thread on Microsoft’s forum, but there is no solution.

The problem occurs only with services that work out more than one minute.
Invoke of this service throws EndpointNotFoundException:

public string Test() {
    Thread.Sleep(60000);
    return "test";
}

But invoke of this service works correctly:

public string Test() {
    Thread.Sleep(58000);
    return "test";
}

I downloaded .NET Framework’s libraries from Windows Phone device and decompile they.

HttpWebRequest has unchangeable timeout in 1 minute.

To confirm, I created an aspx page. If I put Thread.Sleep(60000) in Page_Load, HttpWebRequest will not be able to get an response.
