I’ve moved the solution over to VS2008 .Net 3.5 however I get an error on the following:

public virtual IQueryable Query(Expression<Func> expression = null) where T : class

Could you recommend how to change this the be .NET 3.5 compatible?

Thanks
Gary

There’s a comment on this for deletions. Updates are the same. You need to attach the item to the context first. You could of course refetch it and update the refetched item.

I was trying out the sample and kept hitting the detached entities while performing updates on the object graph. Any idea how this can be over come.
Thanks,

Even though I have a IoC-container, I like to have a factory that gets named and somewhat “states” what could be returned, as opposed to the IoC-container, which is completely dynamic.

ServiceEngine.Instance.IoC.Resolve(IEntityStore))

what are the benafit with this new changes?

- Delete should also attach
- Attach as modified needs Row Version.

[Column(
    Name = @"Version",
    AutoSync = AutoSync.Always,
    DbType = @"rowversion NOT NULL",
    CanBeNull = false,
    IsDbGenerated = true,
    IsVersion = true,
    UpdateCheck = UpdateCheck.Never)]
public Binary Version { get; set; }

The UnitOfWork now has the generic-type on each method instead.
