Mono 2.4
Works with .Net normally

Similar problem:

Create MasterDataSet
Create MergeDataSet
Fill a new table and add to MergeDataSet
Call MasterDataSet.Merge(MergeDataSet,True)
--Fine up to this point

Create MergeDataSet2
Fill a new table and add to MergeDataSet2
Call MasterDataSet.Merge(MergeDataSet2,True)
--Exception occurs

System.InvalidCastException: Cannot cast from source type to destination type.
