Hash Collision Issue When Serializing a DataSet

[agatlin]

I am receiving the following error when I either try to directory serialize a DataSet or attempt to serialize an object which contains a DataSet.

Hash code collision: members 'MarshalByValueComponent.Site' and 'DataSet.Site' have the same hash code = 11520371743981427527

Here are relevant portions of the StackTrace.

I am not sure why a dataset would be causing problems. It probably makes no difference but these datasets were populated from .csv, .xls and .xlsx files. All of them are failing. The hash collision occurs on every attempt to serialize a DataSet.

When I loaded the source locally and ran the unit tests, I got a similar error on the "TestReproForIssue5 / Virtual Property".

I did not have the NET SDK version 2.2.100 installed which was referenced in the global.json so I tried 2.2.200 and 2.1.400 just to see if perhaps a bug had been introduced in .NET. I still got the same error.
