Using TestCategory attribute in Silverlight unit tests

Question

I'm trying to write some unit tests in a Silverlight project and I wanted to tag them with attributes like we do in a regular test project (VS2010). For example, something like this:

[TestMethod]
[TestCategory("BVT")]
public void TestMethod1()
{
}

I added a reference to Microsoft.VisualStudio.QualityTools.UnitTesting.Silverlight.dll whoever, when I try to tag the test case, TestCategory attribute is not available.

Is there a way for me to use all the members/attributes available in Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll?? I can't add that as a reference since I'm working in a Silverlight project.

Thanks!!
