title: ExpectedException attribute is not present yet in Unit Test App (Windows Universal)?
body: <p>I currently working on Unit Test App (Windows Universal) project using .NET Framework 4.6. I would like to add ExpectedException attribute on my test method, but it seems I cannot found the attribute within its Microsoft.VisualStudio.TestPlatform.UnitTestFramework namespace. Anyone have an answer for this issue?</p>
