I have a test declared as: [Test] [ExpectedException(typeof(FaultException<ArgumentException>))] public void ShouldNotBeAbleToDeleteASystemList() When I run

  • 0

I have a test declared as:

    [Test]
    [ExpectedException(typeof(FaultException<ArgumentException>))]
    public void ShouldNotBeAbleToDeleteASystemList()

When I run this in VS2008 targeting .net 3.5 it all works fine and the test passes as the exception is thrown.

I have migrated the solution to VS2010 and changed the target framework to 4.0 and now the test fails with the following details:

System.ServiceModel.FaultException`1[[System.ArgumentException,
mscorlib, Version=4.0.0.0,
Culture=neutral,
PublicKeyToken=b77a5c561934e089]] was
expected

When I write the actual message to the console it is:

System.ServiceModel.FaultException`1[System.ArgumentException]:
This is a system list and cannot be
deleted (Fault Detail is equal to
System.ArgumentException: Value does
not fall within the expected range.).

I have checked and all projects are targeting .net 4.0.

What is going wrong?

    For anyone else who might suffer such a problem. The reason for this error was that the exception was being thrown by a 3rd party component that was compiled against the .net 2.0 framework and the exception thrown was a .net 2.0 class. My code was not interpreting this as the same class. The solution was to change the config of the 3rd party component to add a <supportedRuntime ... /> line to the <startup> section.
