These were probably caused by the changes to how our tests set up their running directory. I'm guessing that the built dir includes the System.IO.Compression and System.IO.Compression.Tests dll, but clrcompression.dll (zlib) was forgotten.

That does raise the question as to why the sqlclient tests are passing since by the above explanation they should also be failing from a missing sni.dll. I also question why this isn't also failing in Jenkins... maybe the directories are set up differently there such that this isn't hit?

I'm looking into it.
