Question

I have problem with streaming. When I send small file like 1kb txt everything is ok, but when I send larger file like 100 kb jpg or 2gb psd I get:

The remote server returned an unexpected response: (400) Bad Request.

I’m using windows 7, VS 2010 and .net 3.5 and WCF Service library

I lost all my weekend on this and I still see this error :/ Please help me

Client:

 var client = new WpfApplication1.ServiceReference1.Service1Client("WSHttpBinding_IService1");

        client.GetString("test");
        string filename = @"d:\test.jpg";
        FileStream fs = new FileStream(filename, FileMode.Open);
        try
        {
            client.ProcessStreamFromClient(fs);
        }
        catch (Exception exception)
        {
            Console.WriteLine(exception);
        }

app.config:

And Wcf ServiceLibrary:

 public void ProcessStreamFromClient(Stream str)
        {

//error occuring even this method is empty
            using (var outStream = new FileStream(@"e:\test.jpg", FileMode.Create))
            {
                var buffer = new byte[4096];
                int count;
                while ((count = str.Read(buffer, 0, buffer.Length)) > 0)
                {
                    outStream.Write(buffer, 0, count);
                }
            }
        }

Answer 1

Try setting:

<serviceDebug includeExceptionDetailInFaults="true" /> 

It will not solve the problem, but you may get an error message stating what the problem is.
