           Summary: DataTable clone fails

public virtual DataTable Clone () creates a new instance with Activator and
than calls CopyProperties(). 
Code tries to copy all properties from old instance to new one, but if you
clone DataSet generated table, you end up with: "System.ArgumentException: Key
duplication when adding: typedName."


So in code it needs one more condition:

for (int i=0; i < ExtendedProperties.Count; i++)
  if (!Copy.ExtendedProperties.Contains(tgtArray.GetValue (i))
    Copy.ExtendedProperties.Add (tgtArray.GetValue (i),
ExtendedProperties[tgtArray.GetValue (i)]);
}


Reproducible: Always

Steps to Reproduce:
1.Create DataTable
2. Add typedName into ExtendetedProperties
3. do table.Clone()
Actual Results:  
Exception

Expected Results:  
to have a clone
