how to extend InitializeService

[Bruno]

Hi,

I have a question about the generated method InitializeService.

I understand the concept of extending a service with partial classes, but is there a way to extend the InitializeService?

I ask this question because of the following scenario:

suppose you have generated the service:

 

Namespace SofiaCarRentalDataService
<System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults := True)>
Public Class SofiaCarRentalService
        Inherits OpenAccessDataService(Of SofiaCarRentalEntityDiagrams)
Public Shared Sub InitializeService(ByVal config As DataServiceConfiguration)
            config.UseVerboseErrors = True
            config.SetEntitySetAccessRule("*", EntitySetRights.All)
            config.SetServiceOperationAccessRule("GetRentalOrdersForCar", ServiceOperationRights.AllRead)
            config.SetServiceOperationAccessRule("GetProfitForCar", ServiceOperationRights.AllRead)
            config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3
End Sub

Protected Overrides Sub HandleException(ByVal args As HandleExceptionArgs)
MyBase.HandleException(args)
End Sub

End Sub
End Class

 

 

the problem with this is that the lines:

            config.SetServiceOperationAccessRule("GetRentalOrdersForCar", ServiceOperationRights.AllRead)
            config.SetServiceOperationAccessRule("GetProfitForCar", ServiceOperationRights.AllRead)

 have to be re-added again and again each time you regenerate the service. Is there a way to extend the InitializeService method in a seperate file?

Hello Bruno,

There is no convenient way to customize the InitializeService method body via code.
Fortunately in your scenario it should be fairly easy to just uncheck both Entity types in the step 3 of the Add Service wizard. This will instruct our code generation to skip any uncheck Entity types so no changes will be required in the code.
Another option that you have is to skip overwriting the already generated file. This scenario is useful if you have added some custom code there that you want to keep.
