My company recently renewed our maintenance license and so I updated Isolator from version 6.1.2.0 to version 6.2.5.0. It broke a test that fakes a LINQ-to-SQL data context. The problem seems to be faking a Table<T>, since the simple test below throws an exception. I have been unable to work around the issue.

[TestMethod]
public void FakeTable()
{
    var fakeTable = Isolate.Fake.Instance<System.Data.Linq.Table<object>>();
    fakeTable.DeleteAllOnSubmit(new object[0]);
}


Full exception details:

Test method MySolution.MyTests.FakeTable threw exception: 
System.NullReferenceException: Object reference not set to an instance of an object.

You uncovered a bug regarding a generic method argument that is constrained to a generic class argument.
We are preparing a fix for this and it should be ready next week.
