==================

Why?

Extending IEntity

public partial class Foo : Entity
{
    public string Name
    {
        get;
        set;
    }
}

Extending IRepository

public static class FooRepository
{
    public static DL.Foo GetByFooName(this IRepository<DL.Foo> repository, string foo)
    {
        if (string.IsNullOrEmpty(foo))
            return null;
        return repository.FirstOrDefault(x => x.Name == foo);
    }
}

Usage

New instance of UnitOfWork

UnitOfWork uow = new UnitOfWork();

Create

uow.Repository<DL.Foo>().Add(new Foo() { Name = "foo" });

Find one

var foo = uow.Repository<DL.Foo>().FirstOrDefault(x => x.Name = "foo" );

Update

foo.Name = "bar";
uow.Repository<DL.Foo>().Update(foo);

Remove

uow.Repository<DL.Foo>().Remove(foo);

Find several records

var results = uow.Repository<DL.Foo>().Where(x => x.CreatedDate < DateTime.Now);

Save Changes

uow.Commit();
