I just found out today that you have to have everything configured in structuremap before calling getInstance. I am using structureMap 2.4.9.

To test this I created.

2 interfaces.

Namespace Interfaces
    Public Interface IClass1
        Sub somefunction()
    End Interface
End Namespace```
```vbnet
Namespace Interfaces
    Public Interface IClass2
        Sub someotherfunction()
    End Interface
End Namespace```
And 2 Classes.

```vbnet
Public Class Class1
    Implements Interfaces.IClass1


    Public Sub somefunction() Implements Interfaces.IClass1.somefunction
        Console.WriteLine("class1")
    End Sub
End Class

Public Class Class2
    Implements Interfaces.IClass2

    Public Sub someotherfunction() Implements Interfaces.IClass2.someotherfunction
        Console.WriteLine("class2")
    End Sub
End Class

And a module to run it.

Module Module1

    Sub Main()
        StructureMap.StructureMapConfiguration.ForRequestedType(Of Interfaces.IClass1).TheDefaultIsConcreteType(Of Class1)()
        StructureMap.ObjectFactory.GetInstance(Of Interfaces.IClass1).somefunction()
        StructureMap.StructureMapConfiguration.ForRequestedType(Of Interfaces.IClass2).TheDefaultIsConcreteType(Of Class2)()
        StructureMap.ObjectFactory.GetInstance(Of Interfaces.IClass2).someotherfunction()
    End Sub

End Module

After getting the class1 you will get this error.

StructureMap Exception Code: 208 Requested type ConsoleApplication3.Interfaces.IClass2 is not configured in StructureMap

This could be a problem when you call a class-library that also uses StructureMap without you knowing. Perhaps there is a simple solution I don’t know about yet. If there is please tell me.

Update

I posted this on the mailing list as well and got a reply from Jeremy.

Well, yeah, that is the way it works. I do need to add some more

documentation for this. I’m thinking about adding some defensive

checks so that if you call StructureMapConfiguration.Anything() after

ObjectFactory is baked that it throws an exception.

For multiple apps/components all using StructureMap together, my

strong suggestion is to put ALL configuration into Registry classes

and just add all the necessary Registry’s to StructureMapConfiguration

at the bootstrapping. Again, something I do intend to document.
