Invoking a web service in a Web API Project...in which layer to invoke?

Question

I am using Microsoft ASP.NET Web API 2 and one of my end points has to internally invoke a legacy non-Microsoft web service (not asmx or svc) .

Which layer should I invoke this in?

I currently have : Repository layer: where all the CRUD calls to DB are done now.

Domain Manager: where respective manager classes invoke the Repository Layer methods.

And my Web API Controller methods invoke the respective Domain Manager methods.

Should I just have another method in my Repository Layer which invokes the web service? And follow the usual pattern above?

Answer 1

The repository layer is the logical place to put it; the data that you're pulling back from the web service will need to be wrapped in domain-specific abstractions, so (in concept) it is essentially another data store alongside your own databases.
