Object scopes for WCF

[mattias.ohrn@gmail.com]

Hi,

I was wondering if there are any plans on introducing more object scopes for WCF? What I'm thinking about is a scope related to the InstanceContext and another related to the OperationContext.

Or is there already something like that?

Cheers,
Mattias

Hi,

The .NET Framework already allows you to do it.

Hi,
I'm not sure exactly what you mean. The service objects will get scopes bound to the operation or instance contexts (depending on how you configure WCF) if they are configured as prototypes in Spring and "Spring.ServiceModel.Activation.ServiceHostFactory " is used.

But for collaborators? I don't know of any non-invasive way of tying their life cycle to a WCF context. The least ugly way I've come up with is to use FactoryObjects to handle this but it clutters the Spring configuration and still requires me to do quite bit more plumbing than in an ASP.NET application.

WCF services

This layer is the top most and will contain the endpoints for my services. Each service method will invoke a method in the Business services layer just below.

Business services

This layer contains all (ok, there not much to it yet, but it will be there later…trust me) business logic. A method within this layer also serves as a transaction demarcation. What I called “business transaction” in my previous post. So this is where the transaction handled by ObjectScope will get started and commited or rolled back. A business service method might invoke several repository methods in the Data access layer just below.

Data access

This layer contains all access to persistent objects. This is where LINQ queries will be executed and other CRUD like methods. So this is methods that uses and manipulates the persistence model.

Did you post in the right thread?
