I've created and proffered a service successfully (at least I think so, no
errors were generated when it was added) but im unable to retrieve the
service later on.

I have an assembly which defines the interface the service uses.
In another assembly, I define the class and give it a Guid attribute. In the
same assembly, I  have a custom package which creates an instance of the
object and proffers the service in its Initialize function. It also carries
the ProvideService attribute.

I'm trying to use the service in a 3rd assembly. I have a custom UI editor
implemented in this assembly. The Edit function of the UITypeEditor receives
an IServiceProvider, but calling GetService with my service information
returns null. The only thing I can think of is that the IServiceProvider
given in the UITypeEditor is different then the one I added my service to.
But I have no idea how to verify this or how to get around it.

Thanks!

Heres a quick code dump...

1st Assembly (the interface assembly)
public interface IArcherEditorProviderService

{

ICodeField ViewCode(ICodeField fld);

}

2nd Assembly  (the package)

[Guid("22E837BC-7CBA-4352-8963-9999022EDCFE")]

public class ArcherEditorProviderService : IArcherEditorProviderService

{

public ArcherEditorProviderService(InstrumentPackage pkg)

{

m_Pkg = pkg;

}

private InstrumentPackage m_Pkg;

public ICodeField ViewCode(ICodeField fld)

{

return m_Pkg.ViewCode(fld);

}

}

[MSVSIP.Helper.ProvideService("22E837BC-7CBA-4352-8963-9999022EDCFE",
ServiceName="ArcherEditorProviderService")]

public class InstrumentPackage :
MSVSIP.Helper.Package,MSSHELL.IVsRunningDocTableEvents3,MSSHELL.IVsSolutionE
vents3,MSSHELL.IVsTaskProvider2

{

protected override void Initialize()

{

// even though the docs dont specify this, the PackageHelper does implement
IServiceContainer so this cast is safe.

((IServiceContainer)this).AddService(typeof(IArcherEditorProviderService),
new ArcherEditorProviderService(this), true);

}

}

3rd Assembly (the consumer)

public class CodeFieldEditor : System.Drawing.Design.UITypeEditor

{

public override object EditValue(ITypeDescriptorContext context,
IServiceProvider provider, object value)

{

IArcherEditorProviderService svc =
(IArcherEditorProviderService)provider.GetService(typeof(IArcherEditorProvid
erService));

if (svc != null)

{

return svc.ViewCode(f);

}

}

}
