entity framework 4 - Catel Extensions EntityFramework5 -

I'm using Catl extension EntityFramework5 repository and functioning of the unit. DailyMacroValue, integer & gt ;, IDailyMacroValueRepository; EntityRepositoryBase & lt: DailyPrice

code:

  public class DailyMacroValueRepository I'm trying to implement storage for a derived class DailyMacroValue where DailyMacroValue {private XXXEntities _dbContext ; Public DailyMacroValueRepository (DbContext dbContext): base (dbContext) as {_dbContext = dbContext XXXEntities; }} Public Interface idelimacro voltage repository: IEntityRepository & lt; Daily Macro Value, Int & gt; {}}   
 Once I store I'm trying to get is excelption:  
 System.Linq.Enumerable.First [TSource] on ( IEnumerable is  1 source, function  2 predicate) at Catel.Data.DbContextExtensions & lt; & Gt; C_  DisplayClass5.b  _3 () in c:. \ Source \ CATEL \ src \ CATEL .Extensions.EntityFramework5 \ Catel.Extensions.EntityFramework5.NET40 \ Extensions \ DbContextExtensions.cs: line 116  
 I do not know the right way to make this implementation that is, a Is also a reference to legacy implementation?
