Structure map and generics (in XML config)

Question

Hi

I'm using the latest StructureMap (2.5.4.264), and I need to define some instances in the xml configuration for StructureMap using generics. However I get the following 103 error:

Unhandled Exception: StructureMap.Exceptions.StructureMapConfigurationException: StructureMap configuration failures:
Error:  103
Source:
Requested PluginType MyTest.ITest`1[[MyTest.Test,MyTest]] configured in Xml cannot be found

Could not create a Type for 'MyTest.ITest`1[[MyTest.Test,MyTest]]'
System.ApplicationException: Could not create a Type for 'MyTest.ITest`1[[MyTest.Test,MyTest]]' ---> System.TypeLoadException: Could not loa

   --- End of inner exception stack trace ---
   at StructureMap.Graph.TypePath.FindType()
   at StructureMap.Configuration.GraphBuilder.ConfigureFamily(TypePath pluginTypePath, Action`1 action)

A simply replication of the code is as follows:

 public interface ITest<T>
 {
 }

 public class Test
 {
 }

 public class Concrete : ITest<Test>
 {
 }

Which I then wish to define in the XML configuration something as follows:

<DefaultInstance
    PluginType="MyTest.ITest`1[[MyTest.Test,MyTest]],MyTest"
    PluggedType="MyTest.Concrete,MyTest"
    Scope="Singleton"
/>

I've been racking my brain, however I can't see what I'm doing wrong - I've used Type.GetType to verify the type actually is valid which it is. Anyone have any ideas?

Thanks !

This is a bug that exists in StructureMap 2.5.x and below. It was fixed in revision 269 in the trunk and will be available in the StructureMap 2.6 release.
