<p class="MsoNormal">-------------I'm re-sending this email since I got it bounced back.</p><p class="MsoNormal"><br></p><p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p><p class="MsoNormal">We've tried adapting one of our DICOM application into a CTK
Based Hosted App. It works well when tried with the ctkhost - we could launch
the app, load the DICOM data and get through different states as well.</p>
<p class="MsoNormal">However when tried launching the same app with different
non-ctk based host, it launches our app but fails to load any data. This
non-ctk based host seems to be written using the WCF as per specification in
DICOM 118.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">On investigating, we noticed that the initial ‘IDLE’ message
sent by the App upon launch is not getting processed by the Non-CTK based host.

<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal">When traced the SOAP communication, we found<span style="color:#1F497D"> </span>out that the messages from the plug-in are
getting to the host, but then they are not processed by WCF because of some
WSDL contacts mismatch. Thus the host does not receive any messages. Here’s the
log message:<span style="color:#1F497D"></span></p>
