Dependency Injection error prevents me from passing an object to CStoreSCP

[saschke]

Describe the bug
Whe creating an Instance of a CStoreSCP using this code

var storageConfiguration = new StorageConfiguration(StoragePath, FileNameExtension, AeTitle);

_server = DicomServerFactory.Create(
IpAddress, Port,
userState: storageConfiguration);

using the sample code of FO-Dicom only adding the userState - parameter it seems to work and the _server is listening but when I echo the _server I get an exception:

[ERROR] Exception listening for DICOM services, System.InvalidOperationException: Unable to resolve service for type 'System.Object' while attempting to activate 'DicomCommunication.DicomStorageScpNonStatic.DicomStorageScp+CStoreSCP'.
bei Microsoft.Extensions.DependencyInjection.ActivatorUtilities.GetService(IServiceProvider sp, Type type, Type requiredBy, Boolean isDefaultParameterRequired)
bei lambda_method(Closure , IServiceProvider , Object[] )
bei FellowOakDicom.Network.DicomServer1.CreateScp(INetworkStream stream) bei FellowOakDicom.Network.DicomServer1.d__56.MoveNext()

To Reproduce
Use the code above, if I leave 'userState: storageConfiguration' away it works but I should be able to pass information to the StorageSCP instance.

Expected behavior
I would expect this to work as I use the proper parameters.

for this version of access

public static IDicomServer Create(
string ipAddress,
int port,
string certificateName = null,
Encoding fallbackEncoding = null,
Logger logger = null,
object userState = null)
where T : DicomService, IDicomServiceProvider
{
return Setup.ServiceProvider.GetRequiredService().Create(ipAddress, port, certificateName, fallbackEncoding, logger, userState);
}

Can you tell me what I am missing?

Environment
Fellow Oak DICOM version: (e.g. 5.0.3.0 but I also get the same error in the newest version)
OS: (e.g. Windows 11)
Platform: (e.g. .NET Framework 4.7.2 but also .NET 7)
