Mostly

with various cultures in CultureInfo..ctor, and a few

Moving to the SqlClient area since the tests are attempting to load SQL-specific assemblies. /cc @cheenamalhotra

Hi @mdh1418

Please provide us more info:

• Have you always seen these failures with System.Data.SqlClient in this environment or has something changed recently that is leading to these issues?
• Could you reproduce the issues in a standalone console app and upload here - that would be easier to diagnose.

@ajcvickers @cheenamalhotra please disregard this issue. Any and all issues tagged os-ios or os-android can be ignored for 5.0. (Apologies for not communicating this broadly enough.)

Only @safern is looking at these. Besides, any fixes here are likely outside of System.Data.

Eh, I think the glob issue already has an issue tracking it..
