I’m calling a web service which returns (after a long while) a large string. This string is more than 64 KB in size, so I had to tweak the config file on the client. Here are the highlighted changes in the app.config file:

<basicHttpBinding>
  <binding name="VLSAdminSoap" closeTimeout="00:01:00" openTimeout="00:01:00"
    receiveTimeout="00:10:00" sendTimeout="00:10:00" allowCookies="false"
    bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
    maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="655360"
    messageEncoding="Text" textEncoding="utf-8" transferMode="StreamedResponse"
    useDefaultWebProxy="true">
    <readerQuotas maxDepth="32" maxStringContentLength="81920" maxArrayLength="16384"
      maxBytesPerRead="4096" maxNameTableCharCount="16384" />

The maxReceivedMessageSize is by default 65536, I made this 655360. I also specified that the response isn’t buffered, but that it will be streamed. I also had to increase the maxStringContentLength.

Also notice that the sendTimeout thas been put to 10 minutes, because the service doesn’t return anything soon.
