Spring .NET problem with <idref> tag in config

According to the help file that comes with the Spring.NET framework, you can inject a dependency defined in a local file using the idref tag along with the "local" attribute.

I tried to do this with no success and hoped someone had some experience to help me.

Below I have a snippet from config where I pass it as a constructor argument, but I tried to set it as a property. Both methods seem to give the same error.

<object id="theTargetObject" type="TestClassLibrary.TargetObject, TestClassLibrary"/>

<object id="theClientObject" type="TestClassLibrary.ClientObject, TestClassLibrary">
    <constructor-arg name="myClass">
        <idref local="theTargetObject"/>
    </constructor-arg>
</object>

Failed to create context 'spring.root': Failed to create object named 'theClientObject' defined in 'file [C: \ Test \ TestApp \ bin \ Debug \ my.config.xml]': Unsatisfactory dependency expressed via constructor with index 0 of type [TestClassLibrary.TargetObject]: Could not convert value of constructor argument [theTargetObject] to required type [TestClassLibrary.TargetObject]: Unable to convert property value of type [System.String] to required type [TestClassLibrary.TargetObject] for property ''.

I think gef was on the right track, but accidentally mixed it up while pasting the snippet. You're looking for the <ref> element :

<object id="theTargetObject" type="TestClassLibrary.TargetObject, TestClassLibrary"/>
<object id="theClientObject" type="TestClassLibrary.ClientObject, TestClassLibrary">
     <property name="myClass">
            <ref local="theTargetObject"/>
    </property>



shorthand for this:

<object id="theClientObject" type="TestClassLibrary.ClientObject, TestClassLibrary">
     <property name="myClass ref="theTargetObject"/>
