asp.net mvc - Entity Framework using Identity - Trying to update a user in the AspNetUsers table -

i having hard time figuring out how update/modify user in aspnetusers table using entity framework , identity. getting error says:

"the entity type manageruserviewmodel not part of model current context."

this make sense, because not mention manageruserviewmodel in applicationdbcontext using. should create new context similar applicationdbcontext , use one? or somehow add manageruserviewmodel applicationdbcontext?

here controller method doing updating when 'save' clicked:

public actionresult edituser([bind(include = "userid, email, username, roles, roleid, rolename")] manageruserviewmodel model)     {         if (modelstate.isvalid)         {             using (var context = new applicationdbcontext())             {                 var store = new userstore<applicationuser>(context);                 var manager = new usermanager<applicationuser>(store);                 applicationuser user = new applicationuser();                 user.email = model.email;                 user.username = model.username;                  if (model.userid == "")                 {                     // since didn't have userid, assume new user                      task.waitany(manager.createasync(user, "password12"));                 }                 else                 {                     // since ef doesn't know product (it instantiated                     // modelbinder , not ef itself, need tell ef                     // object exists , modified copy of existing row                      context.entry(model).state = entitystate.modified;                      task.waitany(manager.updateasync(user));                 }                 if (model.rolename != null && model.rolename != "")                 {                     task.waitany(manager.addtoroleasync(model.userid, model.rolename));                 }                 task.waitany(context.savechangesasync());                 return redirecttoaction("controlpanel");             }         }         return view(model);     } 

and here manageruserviewmodel:

public class manageruserviewmodel {     public string userid { get; set; }     public string email { get; set; }     public string username { get; set; }      [display(name = "role(s)")]     public ienumerable<string> roles { get; set; }      public string roleid { get; set; }      public string rolename { get; set; }      public ienumerable<selectlistitem> rolelist { get; set; }      public static ienumerable<selectlistitem> getroles(string id = "")     {         using (var db = new applicationdbcontext())         {              list<selectlistitem> list = new list<selectlistitem>();             foreach (var role in db.roles)             {                 selectlistitem sli = new selectlistitem { value = role.name, text = role.name};                 list.add(sli);             }              return list;         }     }      public static string getroleid(string role)     {         using (var db = new identitydbcontext())         {             string roleid = db.roles.where(r => r.name == role).first().id;             return roleid;         }     } } 

and here applicationdbcontext:

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

let me know if other code needed.

edit: based on steve's comment, tried creating new context.

public class manageuserdbcontext : identitydbcontext<applicationuser> {     public manageuserdbcontext()         : base("defaultconnection", throwifv1schema: false)     {     }      public dbset<manageruserviewmodel> users { get; set; }      public static manageuserdbcontext create()     {         return new manageuserdbcontext();     }  } 

and in controller method, switched using context new manageuserdbcontext(). not error out, still not update user.

you got right. there no need use dbcontext update user when have usermanager there.

your code should :

public actionresult edituser([bind(include = "userid, email, username, roles, roleid, rolename")] manageruserviewmodel model) {     if (modelstate.isvalid)     {         using (var context = new applicationdbcontext())         {             var store = new userstore<applicationuser>(context);             var manager = new usermanager<applicationuser>(store);             applicationuser user = new applicationuser();             user.email = model.email;             user.username = model.username;              if (model.userid == "")             {                 // since didn't have userid, assume new user                  task.waitany(manager.createasync(user, "password12"));             }             else             {                 // here fetch existing user, update properties , call manager update                    user = manager.findbyid(model.userid)                 user.email = model.email;                 user.username = model.username;                   task.waitany(manager.updateasync(user));             }             if (model.rolename != null && model.rolename != "")             {                 task.waitany(manager.addtoroleasync(model.userid, model.rolename));             }             task.waitany(context.savechangesasync());             return redirecttoaction("controlpanel");         }     }     return view(model); }
