LINQ on the .NET 2.0 Runtime

I wish this help you There are some "Hacks" that involve using a System.Core.dll from the 3.5 Framework to make it run with .net 2.0, but personally I would not want use such a somewhat shaky foundation.
See here: LINQ support on .NET 2.0

Is there any way to set the TableAttribute at runtime, OR any way to do LINQ type switching at runtime?

help you fix your problem You can implement this scenario by manually creating a base class (which is not mapped to any table) and two its 'trivial' descendants (each mapped to one of the tables you work with).
More precisely, the following steps should be performed:
code :
namespace MyContext {

  public partial class ItemBase : INotifyPropertyChanging, INotifyPropertyChanged {
    ... // Generated code.
  }

  [Table(Name = @"ItemXs")]
  public partial class ItemX : ItemBase {}

  [Table(Name = @"ItemYs")]
  public partial class ItemY : ItemBase {}

  public partial class MyDataContext {

    public Devart.Data.Linq.Table<ItemX > ItemXs {
      get { return this.GetTable<ItemX>(); }
    }

    public Devart.Data.Linq.Table<ItemY> ItemYs {
      get { return this.GetTable<ItemY>(); }
    }
  }

}

Hope this helps I think you are looking for something like a Repository Pattern. You would have an interface as follows:
code :
public interface IMyRepository
{
    IEnumberable<MyObject> GetObjects();
}
public class MyRepository : IMyRepository
{
    private Context dbContext;

    IEnumberable<MyObject> GetObjects()
    {
         return dbContext.MyObjects;
    }
}
var dataCollection = from data in repository.GetObjects()
                             where data.Intdata == 5
                             select data;

I wish this help you Coming back to my own question, in case it helps anyone else: MSDN had the answer - You need to overload copyToDataTable as described in

To fix this issue As you are not getting any useful information at the time of the crash, an alternative approach is to attach a debugger to the crashing EXE. There are two ways I suggest:
