I'm using VS2010. Silverlight 4, NUnit 2.5.5, and TypeMock TypemockIsolatorSetup6.0.3.619.msi

In the test project MVVM is implemented, PeopleViewModel is a ViewModel which I want to test.

Please advise if you use other products for unit testing of MVVM Silverlight. Or please help to win this TypeMock. TIA

This is the code of the test:

[Test]
[SilverlightUnitTest] 
public void SomeTestAgainstSilverlight()
{
    PeopleViewModel o = new PeopleViewModel();
    var res = o.People;

    Assert.AreEqual(15, res.Count());
}

While running the test in ReSharper i get the following error:

TestA.SomeTestAgainstSilverlight : Failed******************************************
*Loading Silverlight Isolation Aspects...*
******************************************

 TEST RESULTS:
---------------------------------------------

    System.MissingMethodException : Method not found: 'hv TypeMock.ArrangeActAssert.Isolate.a(System.Delegate)'.

While running test in NUnit i get:
