c# - Working with 2 Entity Framework ASP.Net API -

i have 2 entity framework entities can't access last entity created. i'm working 2 databases created 2 entities. 1 can access other 1 can't.

the error show are

the entity type ms_user not part of model current context.

using (var db = new mobilekeyentities()) {     //check if user exist     var userdb = db.ms_user.where(n => n.userid.equals(username) && n.password.equals(password)).firstasync();      if (userdb != null)         {            identity.addclaim(new claim("role", "user"));         }     } 

please tell me did wrong or need add access other entity. thank you

please make sure dbset instance in dbcontext class same.

public dbset<ms_user> ms_users{get;set;} 

then query should this

var userdb = db.ms_users.where(n => n.userid.equals(username) && n.password.equals(password)).firstasync();
