asp.net mvc 5 - The entity type IdentityRole is not part of the model for the current context -

i having trouble implementing aspnetidentity on mvc project getting error in var line (the entity type identityrole not part of model current context.):

using system; using system.linq; using system.web.mvc;  using ez.models; using microsoft.aspnet.identity.entityframework;  namespace ez.controllers { public class rolecontroller : controller {     applicationdbcontext context;      public rolecontroller()     {         context = new applicationdbcontext();      }        /// <summary>     /// roles     /// </summary>     /// <returns></returns>     public actionresult index()     {         var roles = context.roles.tolist();         return view(roles);     }       /// <summary>     /// create  new role     /// </summary>     /// <returns></returns>    // get: /roles/create     public actionresult create()     {         return view();     }      //     // post: /roles/create     [httppost]     public actionresult create(formcollection collection)     {         try         {             context.roles.add(new microsoft.aspnet.identity.entityframework.identityrole()             {                 name = collection["rolename"]             });             context.savechanges();             viewbag.resultmessage = "role created !";             return redirecttoaction("index");         }         catch         {             return view();         }     }       /// <summary>     /// set role users     /// </summary>     /// <returns></returns>     public actionresult setroletouser()     {         var list = context.roles.orderby(role => role.name).tolist().select(role => new selectlistitem { value = role.name.tostring(), text = role.name }).tolist();         viewbag.roles = list;         return view();     }      [httppost]     [validateantiforgerytoken]     public actionresult useraddtorole(string uname, string rolename)     {         applicationuser user = context.users.where(usr => usr.username.equals(uname, stringcomparison.currentcultureignorecase)).firstordefault();          // display roles in dropdown          var list = context.roles.orderby(role => role.name).tolist().select(role => new selectlistitem { value = role.name.tostring(), text = role.name }).tolist();         viewbag.roles = list;          if (user != null)         {             var account = new accountcontroller();             account.usermanager.addtoroleasync(user.id, rolename);              viewbag.resultmessage = "role created !";              return view("setroletouser");         }         else         {             viewbag.errormessage = "sorry user not available";             return view("setroletouser");         }      } } 

}

i have scripted tables in db.

this exact same code in role-security-mvc5-master project codeproject.com. difference moved tables in db ana di changed connection string. piece missing?

in identitymodel.cs have:

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

if need more code, please let me know , post.

when project created, identity, database @ locadb. when moved tables in db overwrote entire default connection string 1 created e. big probelm here default connection needs providername="system.data.sqlclient" /> , not providername="system.data.entityclient". careful there. credit needs go excellent article daniel eagle: http://danieleagle.com/blog/2014/05/setting-up-asp-net-identity-framework-2-0-with-database-first-vs2013-update-2-spa-template/. tons of detail on how use identity db first.
