Autofac with Azure Mobile Services (ZUMO) InvalidOperationException

[georgep...@hotmail.com]

My WebApiConfig looks like this:

Public Module WebApiConfig
Public Sub Register()
Dim options As ConfigOptions = New ConfigOptions()

Dim config As HttpConfiguration = ServiceConfig.Initialize(New ConfigBuilder(options, Function(configuration, builder)
builder.RegisterType(Of BarMOSDbContext).As(Of IDbContext)() builder.RegisterGeneric(GetType(Repository(Of ))).[As](GetType(IRepository(Of )))
builder.RegisterType(Of DeviceDomainManager).As(Of IDeviceDomainManager)()
Return True
End Function))

End Sub

End Module

Locally everything is ok but when I publish to Azure I get an Invalid operation exception

Error Exception=System.InvalidOperationException: An error occurred when trying to create a controller of type 'DeviceController'. Make sure that the controller has a parameterless public constructor. ---> Autofac.Core.DependencyResolutionException: None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'BarMOS.Service.DeviceController' can be invoked with the available services and parameters:

Why locally everything is OK and when I upload I get this error? Can anyone help me?

Thank you for your time.

We probably need a bit more info to help you out.

• Can you show us the rest of the dependency registrations?
  
• Can you show us the constructors for DeviceController, DeviceDomainManager, and any of the chained custom dependencies required to construct those things?
• Is there anything else that might help - like...
• What's in the "ServiceConfig.Initialize" method?
• Has this worked before and just now stopped or has it always failed to work?
• Are you doing some sort of assembly scanning that might fail on Azure?
• Anything crazy going on in web.config like custom probing paths or anything else?

Thanks,
