During import of a new updated version of a model, I am getting the error "An item with the same key has already been added".
Since the error is very generic, and does not really say what element is cause the problem, I made a quick C# Console project. The call stack reveals the following :

I reverse engineered the AxUtilLib and found the following body in the method throwing the error:
internal void UpdatePaths()
{
Dictionary<int, ModelElementInfo> dictionary = Enumerable.ToDictionary<ModelElementInfo, int>((IEnumerable<ModelElementInfo>) Enumerable.OrderBy<ModelElementInfo, int>((IEnumerable<ModelElementInfo>) this.Elements, (Func<ModelElementInfo, int>) (elmKey => elmKey.ElementHandle)), (Func<ModelElementInfo, int>) (keySelector => keySelector.ElementHandle));
foreach (ModelElementInfo modelElementInfo1 in dictionary.Values)
{
ModelElementInfo modelElementInfo2;
dictionary.TryGetValue(modelElementInfo1.ParentHandle, out modelElementInfo2);
if (modelElementInfo2 != null)
{
switch (modelElementInfo1.ElementType)
{
case ElementType.ClassHeader:
case ElementType.TableHeader:
modelElementInfo1.Path = ElementTypePath.GetListName(modelElementInfo2.ElementType) + "\\" + modelElementInfo2.Name + "\\Header";
continue;
case ElementType.VisualStudioProjectFolder:
case ElementType.VisualStudioProjectFile:
modelElementInfo1.Path = modelElementInfo2.Path + "\\" + modelElementInfo1.Name;
continue;
default:
string listName = ElementTypePath.GetListName(modelElementInfo1.ElementType);
if (!string.IsNullOrEmpty(listName))
{
modelElementInfo1.Path = modelElementInfo2.Path + "\\" + listName + "\\" + modelElementInfo1.Name;
continue;
}
else
{
modelElementInfo1.Path = modelElementInfo2.Path + "\\" + modelElementInfo1.Name;
continue;
}
}
}
else
modelElementInfo1.Path = ElementTypePath.GetListName(modelElementInfo1.ElementType) + "\\" + modelElementInfo1.Name;
}
this.elements = (IList<ModelElementInfo>) Enumerable.ToList<ModelElementInfo>((IEnumerable<ModelElementInfo>) Enumerable.OrderBy<ModelElementInfo, string>((IEnumerable<ModelElementInfo>) this.elements, (Func<ModelElementInfo, string>) (e => e.Path)));
}
}
That Linq-expression is throwing.
Since Microsoft has not been kind enough to let us have the Symbols for debugging, I am sort of searching for the needle in the haystack here. This model contains nearly three thousand elements. Using elimination method is tedious and time consuming. Obviously, I am dealing with an obsolete element handle most likely being modified in a higher layer but removed in the model I am importing.
Any bright ideas on how I would go around to find the duplicate element?
