WCF hosted in Windows Service

[Karch]

I am writing a WCF Service using MSMQ hosted in a Windows Service on Windows
XP. All the required components are installed (.NET3, MSMQ, etc).

For some reason my service tries to start and then stops right away. I have
looked at everything and can't see anything wrong - in fact, I started this
a few weeks ago and I swear it was running at one point.

I have included the app.config and service code below - any idea why my
service will not stay running? Thanks!

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<appSettings>

<!-- use appSetting to configure MSMQ queue name -->

<add key="queueTarget" value=".\private$\NodeManagerXact" />

</appSettings>

<system.serviceModel>

<services>

<service name="Node.Manager.MessagingService"

behaviorConfiguration="MessagingServiceBehavior">

<host>

<baseAddresses>

<add baseAddress="http://localhost:8000/Node.Manager/service"/>

</baseAddresses>

</host>

<!-- Define NetMsmqEndpoint -->

<endpoint address="net.msmq://localhost/private/NodeManagerXact"

binding="netMsmqBinding"

contract="Node.Manager.IMessenger" />

<endpoint address=""

binding="wsHttpBinding"

contract="Node.Manager.IMessenger" />

<endpoint address="mex"

binding="mexHttpBinding"

contract="IMetadataExchange" />

</service>

</services>

Nevermind - I found the problem. I was specifying MSMQ binding which doesn't
support the two-way communication specified in my contract. Thanks anyway -
hopefully this helps someone else.
