+Summary: Cloning a Typed Dataset with relations
+
+Description of Problem:
+When you have a typed dataset, you probably will already have added
+relations in the constructor.
+When cloning such a dataset, it will properly check if tables are already
+existing, and not add them again. But this is not done for the relations.
+
+See Comment in System.Data/DataSet.cs, Clone():
+// tables are often added in no-args constructor, don't add them twice.
+
+I would expect something like that in CopyRelations (DataSet Copy) as well.
+
+foreach (DataRelation MyRelation in this.Relations) {
+  // relations are often added in no-args constructor, don't add them
+  // twice.
+  if (!Copy.Relations.Contains(MyRelation.RelationName)) {
+  ...
