WCF Service Error 413 "Entity Too Large" when pass big byte[]

Question

I got this error when trying to pass large byte[] to wcf service my IService Code:

[OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json, UriTemplate = "SaveFile")]
        SaveFileResult SaveFile(byte[] FileBytes, string FileName, decimal Filesize, string IntegrationSystem, string TellerIndentity, string SendingOfficeCode, string SendingArea);

Service Code:

public SaveFileResult SaveFile(byte[] FileBytes, string FileName, decimal Filesize, string IntegrationSystem, string TellerIndentity, string SendingOfficeCode, string SendingArea)
        {
            FileFactory _FileFactory = new FileFactory();
            string _strExt = Path.GetExtension(FileName);
            IFileDealer _IFileDealer = _FileFactory.GetFileDealer(_strExt);
            SaveFileResult _Result=_IFileDealer.SaveFile(FileBytes, FileName, Filesize, IntegrationSystem, TellerIndentity, SendingOfficeCode, SendingArea);
            return _Result;
        }

wcf service Config:

The binding you've defined in your config file ("basicHttpBindingSettings") is not being used by the WCF service because you do not have an endpoint defined that uses it. With WCF 4.0+, if there are no endpoints defined in the config file, a default endpoint will be created (and out of the box, the binding will be basicHttpBinding with default values).

You have two ways to fix this.

First, you can make your binding definition the default by omitting the name attribute, like this:

<bindings>
  <basicHttpBinding>
    <binding openTimeout="00:01:00" receiveTimeout="05:00:00" 
             sendTimeout="05:00:00" maxReceivedMessageSize="2147483647"
             maxBufferPoolSize="2147483647777" messageEncoding="Text">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                    maxArrayLength="2147483647" maxBytesPerRead="2147483647"
                    maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
</bindings>

This will then be the default configuration for basicHttpBinding.

The second option is to define an explicit endpoint and assign your binding configuration to it via the bindingConfiguration attribute, like this:

<services>
  <service name="<service name>">
    <endpoint address="" binding="basicHttpBinding"
              bindingConfiguration="basicHttpBindingSettings"
              contract="<fully qualified contract name>" />
  </service>
</services>
