Uploading large files to database with Silverlight/WCF

Question

I have a Silverlight application that uses a WCF service that is located in the web project. I have a method in the service that uploads a file to the database in binary format... this all works fine for files up to around 6MB, but when I go over that limit I get the error "The remote server returned an error: NotFound." Which doesn't tell me much.

I have tracing and logging turned on and I get no errors/messages for this. What I figure is that there is a setting for the upload/transfer size, but I don't know where that would be. I've messed around with certain settings in the web.config with no success.

How do I get past this limit?

EDIT: Maybe I should have posted my code in the first place, I have all of the suggested sizes set (and always have had)...

<bindings>
  <basicHttpBinding>
    <binding name="TaskCalendarService.BasicHttpBinding" 
             maxBufferSize="2147483647" 
             maxReceivedMessageSize="2147483647" 
             maxBufferPoolSize="2147483647"
             transferMode="StreamedResponse">
      <readerQuotas maxDepth="2147483647" 
                    maxStringContentLength="2147483647"
                    maxArrayLength="2147483647" 
                    maxBytesPerRead="2147483647"
                    maxNameTableCharCount="2147483647" />
      <security mode="Transport">
        <transport clientCredentialType="None" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

 <behaviors>
  <serviceBehaviors>
    <behavior name="TaskServiceBehavior">
      <serviceMetadata httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

   <service name="TaskCalendarService" 
           behaviorConfiguration="TaskServiceBehavior">
    <endpoint address="" 
              binding="basicHttpBinding" 
              bindingConfiguration="TaskCalendarService.BasicHttpBinding" 
              contract="Pars.Web.TaskCalendarService" />
    <endpoint address="mex" 
              binding="mexHttpsBinding" 
              contract="IMetadataExchange" />
  </service>

As you can now see, everything that I can think of has been set to a large enough size to be able to handle more than 6 MB, but I still get this error.

EDIT: Error

Inner Exception:

{System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound." & vbCrLf & " at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)" & vbCrLf & " at System.Net.Browser.BrowserHttpWebRequest.<>c_DisplayClass5.b_4(Object sendState)" & vbCrLf & " at System.Net.Browser.AsyncHelper.<>c_DisplayClass4.b_1(Object sendState)" & vbCrLf & " --- End of inner exception stack trace ---" & vbCrLf & "

In the pop up error window it also suggests:

InnerException: Check the Response property of the exception to determin why the request failed. InnerException: Check the Status property of the exception to determin why the request failed.

The response property says: {System.NotImplementedException: This property is not implemented by this class." & vbCrLf & " at System.Net.HttpWebResponse.get_Cookies()}

The Status just says: WebExceptionStatus.UnknownError (HttpStatusCode.NotFound)

Stack Trace:

@Graymatter I wish I could tell you that, but I am new to this WCF stuff and I can't really say if it is normal RIA or not. — Barry Franklin
You should try and use something like this: slfileupload.codeplex.com. This will upload the file in blocks. — Graymatter
If you would prefer to use WCF services, please look at the message size limits in this post stackoverflow.com/questions/2517234/… — Graymatter
@Graymatter The first comment is a nice app and it works great, but it doesn't provide any code for how it is accomplishing what it does, also it doesn't upload to the database which is a requirement. Also, I have to have this stuff built into my app, I am not allowed to use 3rd party stuff - the company won't allow it. The second comment... I have all of my reader quotas and the maxRecievedMessageSize set to 2147483647 (2GB?), so that shouldn't be the issue, I wouldn't think. — Barry Franklin

If it is timing out, you can update the custombinding. I'll assume you'll have something like this in Web.config:

<bindings>
  <customBinding>
    <binding name="CustomBinding_HelloWorldService">
      <binaryMessageEncoding />
      <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
    </binding>
  </customBinding>
</bindings>

If so, you can update the binding as such (I'm just setting it to 10 minutes here):

<binding name="CustomBinding_HelloWorldService" sendTimeout="00:10:00">

If you want to look into this a bit more: custombinding
