identitymodels.cs:

public class applicationdbcontext : identitydbcontext<applicationuser> {     public applicationdbcontext()         //: base("defaultconnection", throwifv1schema: false)         : base("appconnection", throwifv1schema: false)     {     }      public static applicationdbcontext create()     {         return new applicationdbcontext();     } }  public class appdatacontext : dbcontext {     public appdatacontext()         : base("appconnection")     { }   } 

web.config:

 <connectionstrings>       <add name="appconnection" connectionstring="data source=.; initial catalog=sis_db;integrated security=sspi;" providername="system.data.sqlclient" />   </connectionstrings>
