  1. POHow can I inject an object into an WCF IErrorHandler implementation with Castle Windsor?
    text
    copied!<p>I'm developing a set of services using WCF. The application is doing dependency injection with Castle Windsor. I've added an <code>IErrorHandler</code> implementation that is added to services via an attribute. Everything is working thus far. The <code>IErrorHandler</code> object (of a class called <code>FaultHandler</code> is being applied properly and invoked.</p> <p>Now I'm adding logging. Castle Windsor is set up to inject the logger object (an instance of <code>IOurLogger</code>). This is working. But when I try to add it to <code>FaultHandler</code> my logger is null.</p> <p>The code for <code>FaultHandler</code> looks something like this:</p> <pre><code>class FaultHandler : IErrorHandler { public IOurLogger logger { get; set; } public bool HandleError(Exception error) { logger.Write("Exception type {0}. Message: {1}", error.GetType(), error.Message); // Let WCF handle things its way. We only want to log. return false; } public void ProvideFault(Exception error, MessageVersion version, Message fault) { } } </code></pre> <p>This throws it's own exception, since <code>logger</code> is null when <code>HandleError()</code> is called.</p> <p>The logger is being successfully injected into the service itself and is usable there, but for some reason I can't use it in <code>FaultHandler</code>.</p> <p><strong>Update</strong>: Here is the relevant part of the Windsor configuration file (edited to protect the innocent):</p> <pre><code>&lt;configuration&gt; &lt;components&gt; &lt;component id="Logger" service="Our.Namespace.IOurLogger, Our.Namespace" type="Our.Namespace.OurLogger, Our.Namespace" /&gt; &lt;/components&gt; &lt;/configuration&gt; </code></pre>
