Strange exception in tests after installing VS2012

Question

I have one computer where I installed vs2012. On that computer a set of unit tests do not pass because the exception below is raised.

This only happens on the machine that VS2012 is installed on and it fails in both VS2012 and VS2010.  All other machines with only VS2010 installed does not happen to.

What is weird is that it happens when I am doing a DataSet.ReadXML(memorystream). The MemoryStream is built from a string that is a valid xml representation of the dataset because. I know this because I changed the mock to a the concreate representations of the interfaces.

Is there something about VS2012 that I need to know about to get this to run?

I am using Teleriks free JustMock.  I am mocking my IBusinessPrinciple and IBusinessIdentity interfaces which inherit IPrinciple and  IIdentity. The Securty project that has the interfaces is .Net 3.5. The unit tests are compiled under .Net 4.0.

Result Message: 
Test method Customer_Tests.CustomerEditList_Tests.CustomerEdit_SaveCreatesRecord threw exception:
System.Exception: Error in Save in  CustomerRecord.

Hi plinville,

Thank you for posting in the MSDN forum.

According to your description, I advice that you can try to uninstall the VS2010 completely on that machine 

having VS2010 and VS2012, and then run your unit tests. 

Or you can directly run your unit tests on another machine only having VS2012. 

After that, you check if the exception still occurs. 

Sometimes two Visual Studios on the same machine may cause some issues.

If possible, you could provide some detailed information about your unit tests so that we can repro 

your scenario to resolve your problem better.

Thanks,

---

I have a similar exceptions with custom principal and identity. All unit tests that uses the same principal are passed except one with return object is DataTable from a remoting service. I'm using .NET 4.0 with Visual Studio 2012. I have both 2010 and 2012 Visual Studio installed on my PC. The same unit tests are passed in Visual Studio 2010 without any exceptions.

If I change this remoting service to return a string, then there is no problem.

Any ideas?

I got the same issue

Fixed by applying the tip provided here

If i change my Identity from

public MyIdentity : GenericIdentity
{ }

to

public MyIdentity : MarshalByRefObject, IIdentity
{ }

all of my tests are gettin green.
