VelocityDB & VelocityGraph | Issues with AllObjects<T> and UpdateTypeVersion

1) If I just call session.AllObjects<T> , I get an exception

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
[ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.]

VelocityDb.OfType.a(SessionBase A_0) +904
VelocityDb.b.v() +1050
VelocityDb.a.g() +221

But when I use session.AllObjects<T>(false), there is no such exception. I don't know is it a bug or not.

2) I need to update class with already persisted objects before after adding another indexable value (i.e.[Index]private string _anotherIndex ), but I cannot.

There is an exception (I've tried session.UpdateClass in different places)

Line 23:                 session.UpdateClass(typeof(DomainObject));
Line 24:                 foreach(var o in session.AllObjects<DomainObject>(false))
Line 25:                     o.UpdateTypeVersion();
Line 26:                 
Line 27:                 session.Commit();

What do I do wrong?
