Obviously doing it the way I suggested means that the connection string would still be in the app.config even when running n-tier, this could be a security vulnerability! :)

Hello Siyfion,
I've adopted a quite similar structure while waiting for an answer...for now I've a .DA assembly that contains the edmx and the Client parts (repository, proxy) are as shared link for the models/view since it's still under discussion forn ow I've cloned them
Thanks

You could:

- Separate the model into it's own assembly and reference it from the main project and the n-tier projects.
- Then put a duplicate connection string in the main project's App.config file
- Make the connection configurable in any way you like, ie. via config settings (bad coding, but you get the example!)

var dataSource = ConfigurationManager.AppSettings["SqlSource"];
var useWebService = Boolean.Parse(ConfigurationManager.AppSettings["UseWebService"]);
var entityServiceOption = useWebService
? EntityServiceOption.UseDistributedService
: EntityServiceOption.UseLocalService;

var serviceHost = ConfigurationManager.AppSettings["ServiceHost"];

var connectionOptions = new ConnectionOptions(
name: "TestConnection",
shouldConnect: true,
dataSourceExtension: dataSource,
serviceKey: serviceHost,
entityServiceOption: entityServiceOption);
            
return connectionOptions;

Hello,
I've got a wcf application based on ideablade n-tier application and cocktail, I've been asked to mantain 2 version of the software, one that's for the major of user that's n-tier and a version that direcly communicates with the database (so EDMX file inside the module), i was wondering how to do it at best without having to rewrite all the code, should I create modules that have the edmx file linked as file? (Add as link feature) (and adding the repository files to the project as well?)
 
Thanks
