The maximum message size quota for incoming messages (65536) has been exceeded

I am using WCF for file uploading and downloading. uploading is successful but when i downloading a large file i found this error

Error : The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

My Service.config file has the following code.

<system.web>     <compilation debug="true" />     <httpRuntime executionTimeout="4800" maxRequestLength="2147483647" />     </system.web>   <system.serviceModel>     <bindings>       <basicHttpBinding>         <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferPoolSize="524288">           <readerQuotas maxDepth="32" maxStringContentLength="2147483647"              maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"  />         </binding>       </basicHttpBinding>       <!--<webHttpBinding>         <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />       </webHttpBinding>-->     </bindings>     <services>       <service name="WITSService.WITSService">         <clear />         <endpoint binding="basicHttpBinding" contract="WITSService.WITSService" />       </service>     </services>      <behaviors>       <serviceBehaviors>         <behavior>           <serviceMetadata httpGetEnabled="true"/>           <serviceDebug includeExceptionDetailInFaults="false"/>           <dataContractSerializer maxItemsInObjectGraph="2147483646"/>         </behavior>       </serviceBehaviors>       <endpointBehaviors>         <behavior name="myEndPointBehavior">           <dataContractSerializer maxItemsInObjectGraph="2147483646"/>         </behavior>       </endpointBehaviors>     </behaviors>      <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />   </system.serviceModel> 

can any one help me how to increase MaxReceivedMessageSize

Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

You need to set basicHttpBinding -> MaxReceivedMessageSize in the client configuration.
