VS2010 Test solution

I have come across a scenario where the DataContractJsonSerializer does not correctly deserialize the date "6/24/2010 12:00:00 AM" correctly. I ran my test project on my PC using Visual Studio and the value is deserialized correctly. However, when I run the test on my Mac using Mono, it pulls back 01/01/0001.

I have attached a test project which demos the scenario.

From Mono on Mac:

Starting Test
1/1/0001 12:00:00 AM
Finished Test

Press any key to continue...

From PC on Windows:

Starting Test
6/24/2010 12:00:00 AM
Finished Test

Fixed on master and mono-2-10

The added test was wrong and did not consider the fact that it is TimeZone dependent. Hence the test also failed on .NET Framework. I revised it so that it won't get stuck when we import referencesource. See also https://bugzilla.novell.com/show_bug.cgi?id=586169
