WCF File Upload Large File - wcf

Question

I've been doing a fair bit of research over the last two days to find a solution to my problem but to no avail.
I have created a WCF service like so:
[OperationContract]
void CopyMemberFile(string memberNumber, string fileName, byte[] fileBytes);
And I call it from my client like so from a page_load event:
byte[] filebytes = null;
using (Stream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
{
filebytes = new byte[fs.Length];
fs.Read(filebytes, (int)0, (int)fs.Length);
}
client.CopyMemberFile(memberNumber, Path.GetFileName(file), filebytes);
My configuration is like so:

The error I'm getting is this:

I can upload files at only a few KB each but any larger than say 8KB and thing just fails
Any help would be fantastic.
Calling code:
protected void Page_Load(object sender, EventArgs e)
{
var file = Request.Form["name"];
var memberNumber = Request.Form["memberNumber"];
var tempId = Guid.NewGuid();
var client = new MembershipApplicationsServiceReference.MembershipApplicationsClient();
client.LogEvent("Entered Upload.aspx");
try
{
byte[] filebytes = null;
using (Stream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
{
filebytes = new byte[fs.Length];
fs.Read(filebytes, (int)0, (int)fs.Length);
client.LogEvent("Starting service call from Upload.aspx");
client.CopyMemberFile(memberNumber, Path.GetFileName(file), filebytes);
}
client.LogEvent("Completed service call from Upload.aspx");
}
catch (Exception ex)
{
Debug.WriteLine(ex.StackTrace);
client.LogEvent("Upload.aspx Error: " + ex.Message + ex.StackTrace);
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
finally
{
client.LogEvent("Finishing up");
}
}

Looking at your service's config file, you're using .NET 4.0 and you're not specifying any binding, so you're going to receive the default settings for basicHttpBinding. As suggested in the comments above, update your config file for your service like this:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IMembershipApplications"
closeTimeout="00:01:00"
openTimeout="00:01:00"
receiveTimeout="00:10:00"
sendTimeout="00:01:00"
allowCookies="false"
bypassProxyOnLocal="false"
hostNameComparisonMode="StrongWildcard"
maxBufferSize="2147483647"
maxBufferPoolSize="2147483647"
maxReceivedMessageSize="2147483647"
messageEncoding="Text"
textEncoding="utf-8"
transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="128"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
<security mode="None">
<transport clientCredentialType="None"
proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName"
algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service name="YourServiceName">
<endpoint address=""
binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IMembershipApplications"
contract="YourFullyQualifiedContractName" />
</service>
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
This will tell WCF to use your settings for the basicHttpBinding rather than the .NET defaults.
Alternatively, you can omit the name attribute on the binding definition and WCF will use it as the default binding for all services handled by the config file (if you have more than one).
If that doesn't help, or if you're getting a different error now, let us know and we'll take it from there.
