Calling WCF service problem

I have a simple WCF service looks like this:

public class FileUploadService : IFileUploadService
    {
        #region IFileUploadService Members

        public string DoUpload(string FileName, string Content)
        {
            System.Threading.Thread.Sleep(3000);
            return FileName;
        }

        #endregion
    }

I have code to call this service in my silverlight control:

string fileName = "somestring";

string content = "somerandomstring";

var fs = new FileUploadService.FileUploadServiceClient();
fs.DoUploadCompleted +=new EventHandler<FileUploadService.DoUploadCompletedEventArgs>(fs_DoUploadCompleted);
fs.DoUploadAsync(fileName, content);

void fs_DoUploadCompleted(object sender, FileUploadService.DoUploadCompletedEventArgs e)
{
            if (e.Error == null)
            {

              //do something with the e.Result

}

}

It works fine until I put a longer string in the content variable. I would get an error in the following generated code in Reference.cs:

public string EndDoUpload(System.IAsyncResult result)

{
                object[] _args = new object[0];
                string _result = ((string)(base.EndInvoke("DoUpload", _args, result))); //Error here
                return _result;
}

The error message is:

An exception of type 'System.ServiceModel.ProtocolException' occurred in System.ServiceModel.dll but was not handled in user code

Additional information: [UnexpectedHttpResponseCode]
Arguments:Not Found

I did all tests to see how long I can set the content string variable without getting error. The magic number is 8192. If the string length is greater than 8192, I would get the error. But works fine for shorter string.

Is this a bug?

Re: Calling WCF service problem

I think you've hit the limit for the default max size on a web service request. This thread might help you:

        public string DoUpload(string FileName, string Content)
        {
            System.Threading.Thread.Sleep(3000);
            return FileName;
        }

On a side note, I'm curious, why do you have a Sleep statement there?

Thanks jackbond!

The solution in the link you provided solved problem.

By the way, the Thread.Sleep statement is there for testing purpose. It will be replaced with real code.
