Hello.
DataSet diffgram serialization missed row ID when serialize DataTable row with
all NULL values. 
So MS .NET DataSet can not deserialize data getted from the MONO server.

here is example of the serialized diffgram:

<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
        <NewDataSet>
                <Data5_x0040_Unit5 diffgr:id="Data5 at Unit51" msdata:rowOrder="0"
diffgr:hasChanges="modified">
                        <ColString>Test catalog</ColString>
                        <pk>TestCaseInterface.IBizClass5, TestCaseInterface,
Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null:80065781-b552-44c6-b9ce-3dc6d13a5228:13c73feb-d4ec-46a3-ac32-61d70a529ebe</pk>
                </Data5_x0040_Unit5>
                <Data5_x0040_Unit5 diffgr:id="Data5 at Unit52" msdata:rowOrder="1"
diffgr:hasChanges="modified">
                        <pk>TestCaseInterface.IBizClass5, TestCaseInterface,
Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null:80065781-b552-44c6-b9ce-3dc6d13a5228:80065781-b552-44c6-b9ce-3dc6d13a5228</pk>
                </Data5_x0040_Unit5>
        </NewDataSet>
        <diffgr:before>
                <Data5_x0040_Unit5 diffgr:id="Data5 at Unit51"
msdata:rowOrder="0">
                        <ColString>Test catalog</ColString>
                </Data5_x0040_Unit5>
                <Data5_x0040_Unit5 />
        </diffgr:before>
</diffgr:diffgram>

note diffgr:before/Data5_x0040_Unit5 element

for proper deserialization it must be like this
<Data5_x0040_Unit5 diffgr:id="Data5 at Unit52" msdata:rowOrder="1" />
