c# - One-to-One Relation EF and Seed Method -


am working on mysql connection (code first) project. have following structures in place, require one-to

public class identity {     [databasegenerated(databasegeneratedoption.identity)]     [key]     public long identityid { get; set; }     public string username { get; set; }     public string password { get; set; }     public virtual profile profile { get; set; } }    public class profile {     [databasegenerated(databasegeneratedoption.identity)]     [key]     public long profileid { get; set; }      public virtual identity identity { get; set; }      public string firstname { get; set; }  }

i using fluent api specifying one-to-one relation follows

        modelbuilder.entity<model.user.profile>()             .haskey(e => e.profileid);           modelbuilder.entity<model.user.identity>()                     .hasrequired(s => s.profile)                     .withrequiredprincipal(a=>a.identity);

and seed method looks follows.

        context.useridentity.addorupdate( new model.user.identity()                     {                         username = "abc",                         password = "def",                         profile = new model.user.profile                         {                             firstname = "hij"                         }                      }              );  context.savechanges();

however, running error when updating db via update-database commmand. following error comes up

system.invalidoperationexception: dependent property in referentialconstraint mapped store-generated column. column: 'profileid'.

could guide me ?

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
