I am trying to run TestWhiteningCommandLine test on netfx. The test using Maml.Main and it is not able to load the whitening module.

Adding Type t = typeof(VectorWhiteningTransformer); helps solve the issue but I think we may require more permanent solution

Does SymSgd, Ols learner tests works fine?

this looks like indication what we just don't link HalLearner project properly to our tests.
