    <p>I'm trying to upload a photo taken by the iphone to the <strong>WCF RESTful server</strong>, i've looked all over the web for examples and other answers around the issue, but i can't give with the solution.</p> <p>The app is written in <strong>iOS6</strong>, and i'm using <strong>AFNetworking 2.0</strong> to upload the image. As in the simulator the camera doesn't work, i've been trying with a library photo. I think the problem is in format differences, <strong>WCF is requesting for a Stream parameter</strong>, and i don't know how AFNetworking is sending the info...</p> <p>Here is the <strong>WCF code:</strong></p> <pre><code>[WebInvoke(Method = "POST", UriTemplate = "FileUpload")] public void FileUpload(Stream stream) { try { byte[] buffer = new byte[10000]; stream.Read(buffer, 0, 10000); FileStream f = new FileStream("C:\\temp\\sample.jpg", FileMode.OpenOrCreate); f.Write(buffer, 0, buffer.Length); f.Close(); stream.Close(); System.Console.WriteLine("Recieved the image on server"); } catch (Exception e) { System.Console.WriteLine("ERROR: " + e.ToString()); } } </code></pre> <p><strong>iOS code:</strong></p> <pre><code>AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSDictionary *parameters = @{@"foo": @"bar"}; NSURL *filePath = [NSURL fileURLWithPath:@"Users/juan/Library/Application Support/iPhone Simulator/6.1/Media/DCIM/100APPLE/IMG_0001.JPG"]; [manager POST:@"http://192.168.2.3:8732/wave/FileUpload" parameters:parameters constructingBodyWithBlock:^(id&lt;AFMultipartFormData&gt; formData) { [formData appendPartWithFileURL:filePath name:@"image" error:nil]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Success: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }]; </code></pre> <p>Testing the web service in <strong>fiddler</strong>, it throws the same error by sending an image, <strong>415 unsupported media</strong>.</p> <p>I let the <strong>app.config</strong> of the server:</p> <pre><code>&lt;configuration&gt; &lt;system.web&gt; &lt;httpRuntime maxRequestLength="2097151" useFullyQualifiedRedirectUrl="true" executionTimeout="14400" /&gt; &lt;/system.web&gt; &lt;system.serviceModel&gt; &lt;services&gt; &lt;service name="WcfJsonRestService.waveWS"&gt; &lt;endpoint address="http://localhost:8732/wave" binding="wsHttpBinding" bindingConfiguration="wsHttp" contract="WcfJsonRestService.IWaveWS"/&gt; &lt;/service&gt; &lt;/services&gt; &lt;bindings&gt; &lt;wsHttpBinding&gt; &lt;binding name="wsHttp" maxReceivedMessageSize ="50000000" messageEncoding="Mtom" maxBufferPoolSize="50000000" &gt; &lt;readerQuotas maxArrayLength="50000000" /&gt; &lt;security mode="None" /&gt; &lt;/binding&gt; &lt;/wsHttpBinding&gt; &lt;/bindings&gt; &lt;/system.serviceModel&gt; &lt;system.diagnostics&gt; </code></pre> <p>Any idea or suggestion how to solve this? Every idea is welcome</p> <p><strong>EDIT:</strong> Finally i solved myself, the problem was in the app.config.</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;configuration&gt; &lt;system.serviceModel&gt; &lt;bindings&gt; &lt;webHttpBinding&gt; &lt;binding name="WebConfiguration" maxBufferSize="65536" maxReceivedMessageSize="2000000000" transferMode="Streamed"&gt; &lt;/binding&gt; &lt;/webHttpBinding&gt; &lt;/bindings&gt; &lt;behaviors&gt; &lt;endpointBehaviors&gt; &lt;behavior name="WebBehavior"&gt; &lt;webHttp /&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior name="WcfJsonRestService.waveWS"&gt; &lt;serviceMetadata httpGetEnabled="true" httpGetUrl="" /&gt; &lt;serviceDebug includeExceptionDetailInFaults="false" /&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;/behaviors&gt; &lt;services&gt; &lt;service name="WcfJsonRestService.waveWS"&gt; &lt;endpoint address="http://localhost:8732/wave" binding="webHttpBinding" behaviorConfiguration="WebBehavior" bindingConfiguration="WebConfiguration" contract="WcfJsonRestService.IWaveWS"/&gt; &lt;/service&gt; &lt;/services&gt; &lt;/system.serviceModel&gt; &lt;startup&gt; &lt;supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/&gt; &lt;/startup&gt; </code></pre> <p></p>

    3. COwith this line: `stream.Read(buffer, 0, 10000);` you can read maxmium 10000 bytes, your image is larger than the buffer, so this is the 1 problem

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
