c# - Getting a null return from a GetUserManager call when using AspNet.Identity -
i have attempted go through few examples of utilizing microsoft.aspnet.identity , microsoft.asp.identity.owin within webforms. have been able create database tables within current database (i choose keep both aspnet tables user, stores , roles manager in same database application) , have model, controller, view , app_start folders in place needed files.
the line having issues in code behind file forgetpassword in account folder: var manager = context.getowincontext().getusermanager();
here how have files set up: app_start: identityconfig.cs

any on leading me why getting null value , how can correct reference appreciated!
