c# - Entity Framework one context many databases -

in app, have 1 context user can select 1 of many databases during login. these databases based on same context , connection strings configured in web.config.

i have class caches user details:

public class userdetais {     public string token { get; set; }     public string connectionstring { get; set; } } 

once user logs in, new userdetails object added cache later requests.

on receiving further requests, controller gets user's details cache , passes them on service, example:

public class customertypecontroller : apicontroller {     private readonly icustomertypeservice customertypeservice;      public customertypecontroller(icustomertypeservice customertypeservice)         : base(logservice)     {         this.customertypeservice = customertypeservice;     }      protected override void initialize(httpcontrollercontext controllercontext)     {         base.initialize(controllercontext);          var token = controllercontext.request.properties["token"] string;         var details = usercache.get(token);          customertypeservice.setuserdetails(details);     }      } 

the service sets user details in unit of work, , @ stage, unit of work creates new context based on user's connection string.

this solution works, looks little hacky. there better way implement one-context-many-databases strategy?
