<p class="MsoNormal">Hello folks,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have some problems with the WCF binding library which I got advice from IRC to share here:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l1 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>The Client does not send to the server (fill up the queue and then quit), even in one-way communication manner. Instead, it waits for confirmation;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l1 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>I cannot start multiple server worker processes on the same queue, which greatly limits the number of instances (to one) of running server processes;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l1 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">3)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>All communication is lost when either the client or the server dies, even in one-way communication.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Microsoft’s Message Queue WCF service does not have this limitation. It could be used only for one-way communication only, though, and therefore does not fit all the use cases we have.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think the problems above are related to not having durable queues – the WCF binding always creates temporary queues. I have been given the advice of communicating directly with the queue on IRC. I guess the only available option to us
is to create another binding, which could support:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>One-way communication (fire-and-forget), using durable queues;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>Multiple worker processes (self-hosted WCF), using the same durable queues;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>Possible duplex and/or direct communication without the need for both parties to be online at the same time.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Do you have any insight on how this would be possible with the current driver? I guess, if it requires minor changes, it shouldn’t be very hard to achieve, provided that the broker can create multitude of reply queues and a single request
queue.<o:p></o:p></p>
