c# - Method called by Web UI doesn't returns results -

-

i'm confused, have method:

        public ienumerable<professionalmodel> getallprofessionals()         {             return context.professionalcontext                 .include(x => x.useraccountmodel)                 .include(x => x.useraddressmodel).tolist();         }

if call using console ui return 1 record (it works), if call using mvc application returns no 1 record!

console ui:

        professionalcontext pcontext = new professionalcontext();         var list = pcontext.getallprofessionals();         foreach (var in list)         {             console.writeline(i.name);         }          console.readkey();

mvc web ui:

    public class professionalcontroller : controller     {         public professionalcontext professionalcontext { get; set; }          public actionresult index()         {             professionalcontext = new professionalcontext();              var professionals = professionalcontext.getallprofessionals();              if (professionals == null)             {                 return httpnotfound();             }              return view(professionals);         }     }

and problem not @ view, because i've debugged , var professionals have no records.

any idea?

edit

my context:

public class tccdatabase : dbcontext {     public dbset<useraccountmodel> useraccountcontext { get; set; }     public dbset<professionalmodel> professionalcontext { get; set; }     public dbset<useraddressmodel> useraddresscontext { get; set; }  }

note return type 

ienumerable<professionalmodel>

which means debugger may not display elements in list till ask evaluate.

double check there no records in professionals variable follows:

    public actionresult index()     {         professionalcontext = new professionalcontext();          var professionals = professionalcontext.getallprofessionals();          debug.assert(professionals != null && professionals.any());          if (professionals == null)         {             return httpnotfound();         }          return view(professionals);     }

and if want see results instantly in debugger etc. this:

public list<professionalmodel> getallprofessionals() { //body }
