wcf .net 4.6 iis 7.5 413错误

Question

我在从asp.net应用程序/控制台应用程序调用wcf服务时遇到问题。我得到的错误是“远程服务器返回错误：（413）请求实体太大。”

双方的web.config和app.config中有下面几行：

<system.serviceModel> 
    <bindings> 
    <basicHttpBinding> 
    <binding name="BasicHttpBinding_IWCLService" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text"> 
    <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> 
    </binding> 
    </basicHttpBinding> 
    </bindings> 
    <client> 
    <endpoint address="http://[server]/[projectname].wcfservice/WCLService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IWCLService" contract="wclSvc.IWCLService" name="BasicHttpBinding_IWCLService" /> 
    </client> 
    </system.serviceModel> 

这是WCF服务本身的web.config文件：

<?xml version="1.0" encoding="UTF-8"?> 
    <configuration> 
     <appSettings> 
     <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />

     <staticContent> 
     <mimeMap fileExtension=".svc" mimeType="application/octet-stream" /> 
     </staticContent> 
     <handlers> 
     <add name="svc-integrated" path="*.svc" verb="*" type="System.ServiceModel.Activation.HttpHandler" resourceType="File" preCondition="integratedMode" /> 
     </handlers> 
     <security> 
     <requestFiltering> 
      <requestLimits maxAllowedContentLength="104857600" /> 
     </requestFiltering> 
     </security> 
    </system.webServer> 

    </configuration>
