in system.servicemodel/services/service set binding "webhttpbinding" don't define bindingconfiguration. problem didn't set webhttpbinding in system.servicemodel/bindings. set basichttpbinding , set name webhttpbinding! in fact complete binding not used, because service-element looks default (because didn't define bindingconfiguration) webhttpbinding , not basichttpbinding name webhttpbinding! reason why upload fails files bigger 64k. because exceed default quota of 64k. hope understand me :) mixing default binding names quite error-prone ;)

update:

this system.servicemodel-section should work:

<services>   <service name="ezfindwcfservice.ezfindwebservice"             behaviorconfiguration="webhttpbehavior" >     <endpoint address=""                binding="webhttpbinding" bindingconfiguration="configwebhttp"               behaviorconfiguration="ezfindwcfservice.ezfindwebserviceaspnetajaxbehavior"               contract="ezfindwcfservice.ezfindwebservice" />   </service> </services>  <behaviors>   <endpointbehaviors>     <behavior name="ezfindwcfservice.ezfindwebserviceaspnetajaxbehavior">       <!--<enablewebscript />-->       <webhttp/>     </behavior>   </endpointbehaviors>   <servicebehaviors>     <behavior name="webhttpbehavior">       <servicemetadata httpgetenabled="true" />       <servicedebug includeexceptiondetailinfaults="true" />       <datacontractserializer maxitemsinobjectgraph="2147483647" />     </behavior>   </servicebehaviors> </behaviors>  <bindings>   <webhttpbinding>     <binding name="configwebhttp"              opentimeout="00:10:00" closetimeout="00:10:00" receivetimeout="00:10:00" sendtimeout="00:05:00"              maxbuffersize="2147483647" maxbufferpoolsize="2147483647" maxreceivedmessagesize="2147483647">       <readerquotas maxdepth="64" maxstringcontentlength="2147483647" maxarraylength="2147483647"                      maxbytesperread="2147483647" maxnametablecharcount="2147483647" />     </binding>   </webhttpbinding> </bindings> 

left out default settings (e.g. binding/security) make config bit more slim. 1 more thing: i'd careful settings quotas int32.maxvalue. may ok testing, keep in mind set values down, when go production.
