Upload greater than 8 MB streams through WCF Service

Question

I'm trying to upload photo(attachment stream) through window service , using REST configuration (webHttpBinding), but I get this exception

here is the binding configuration I used (I tried all of them and the error still as it )

      <webHttpBinding>
        <binding name="maxRequest" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode ="Transport"></security>
        </binding>

       
        <binding name="maxRequestBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"  >
          <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode ="Transport">
          </security>
          
        </binding>

        <binding name="BasicHttpBinding_IFileService" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"
          transferMode="Buffered" useDefaultWebProxy="true" 
          >
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />

          <security mode ="Transport"></security>
        </binding>

I had also tried the solution for IIS posted here

https://techcommunity.microsoft.com/t5/iis-support-blog/solution-for-request-entity-too-large-error/ba-p/501134

however, all of the above doesn't work.

here is my endpoint behavior

      <endpointBehaviors>
        <behavior name="rest">
          <webHttp faultExceptionEnabled="true" helpEnabled="true"/>
          <dataContractSerializer maxItemsInObjectGraph="1365536" />
        </behavior>
      </endpointBehaviors>

here is the contract

and For more information the image size is just 100KB.

WCF default transmission message size is 64KB, you need to use MaxReceivedMessageSize to set the transmission message size.

<system.serviceModel>
    <services>

        <service name="ConsoleApp1.RawDataService" behaviorConfiguration="ServiceBehavior">
            <host>
                <baseAddresses>
                    <add baseAddress="http://localhost:8012/ServiceModelSamples/service"/>
                </baseAddresses>
            </host>

            <endpoint address=""
                      binding="webHttpBinding"
                      contract="ConsoleApp1.IReceiveData"
                      behaviorConfiguration="ESEndPointBehavior" bindingConfiguration="RestfullwebHttpBinding"/>
        </service>
    </services>
    <bindings>
        <webHttpBinding>
            <binding name="RestfullwebHttpBinding" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
            </binding>
        </webHttpBinding>
    </bindings>
    
    
    <behaviors>
        <endpointBehaviors>
            <behavior name="ESEndPointBehavior">
                <webHttp helpEnabled="true"/>
            </behavior>
        </endpointBehaviors>

        <serviceBehaviors>
            <behavior name="ServiceBehavior">
                <serviceMetadata/>
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>

    </behaviors>

</system.serviceModel>

You need to apply RestfullwebHttpBinding to the endpoint.

Feel free to let me know if the problem persists.
