.net - ShortGuid with Entity Framework -

i installed shortguid nuget , use key table. store 22-char string in database rather guid, it's easier find records when debugging. how entity framework create column?

i tried adding:

public shortguid newcol { get; set; } 

but no column added. tried:

[column(typename = "nvarchar")] [maxlength(22), minlength(22), stringlength(22)] public shortguid newcol { get; set; } 

but still no column. presumably ef doesn't understand i'm trying ignores column? works fine if use guid:

public guid newcol { get; set; } 

i suppose use 22-char string column, ideally i'd use shortguid type. possible?

i have experienced similar entity framework in past. far understand, type of column cannot complex type. limitation of entity framework (but not 100% sure this).

i share in these sort of situations, though aware answer more of workaround proper answer question.

i create 2 properties in class: 1) property acting column in database , 2) property intended keep in class. following code snippet explain trying do.

event.cs:

namespace mycontext.model  {     public partial class event      {         [key]         public int eventid { get; set; }          public string accesstokenstr { get; set; }          // [notmapped] tells entity framework not make column following property         [notmapped]         public shortguid accesstoken          {                         {                 return new shortguid(accesstokenstr);             }              set             {                 accesstokenstr = value.tostring();             }         }     } } 

hope helps.
