c# - StructureMap - different concrete instance based on inheritance of generic type in parent -

i'm not sure if possible. might have make changes want work. maybe need 2 repository classes. i'm open suggestions make work can connect 2 different entity framework data contexts.

i have setup user profiles stored in shared database sub-sites, , other models in site database specific site. there going 2+ sites , use shared entity context shared models.

first have profile model in shared models library

public class profile : coreobject, ishared {     //...properties } 

for comparison, here object in subsite models library

public class game : coreobject {     //...properties } 

then have repository interface

public interface irepository<t> : idisposable t : coreobject 

and concrete

public class repository<t> : irepository<t> t : coreobject {     //system.data.entity.dbcontext     private dbcontext context { get; set; }      public repository(idbcontextfactory dbcontextfactory)     {         context = dbcontextfactory.getdbcontext();     }      //...other methods accessing dbcontext } 

and have factory interface

public interface idbcontextfactory : idisposable 

and factory concrete, have 2 classes can define underlying context , objects available. onlything different class library datacontext located in.

public class dbcontextfactory : idbcontextfactory {     private readonly dbcontext _context;      public dbcontextfactory(string connectionstring)     {         // datacontext shared.data.context.datacontext in 1 file         //  , subsite.data.context.datacontext in another.  both          //  same except concrete initializer         _context = new datacontext(connectionstring);     }      public dbcontext getdbcontext()     {         return _context;     } } 

here's datacontext looks like

public class datacontext : dbcontext, idatacontext 

dbcontext system.data.entity. idatacontext interface both datacontexts extend , looks this.

public interface idatacontext {     database database { get; } } 

what want do, if type t in repository inherits ishared, idbcontextfactory use shared.data.context.dbcontextfactory, otherwise use subsite.data.context.dbcontextfactory
