@CesarBS please let us know when you are doing this. We want to make sure EF tests are run an work great on Mac.

All EF tests are passing on OSX CI now. This required manually setting locale on our CI agents.

For future reference, due to https://github.com/dotnet/coreclr/issues/2531 I had to manually set environment variables to ensure the thread culture is "en-US", not "en-US-POSIX".

Env variables I added:

Var Name	Value
LANG	en_US.UTF-8
LC_COLLATE	en_US.UTF-8
LC_CTYPE	en_US.UTF-8
LC_MESSAGES	en_US.UTF-8
LC_MONETARY	en_US.UTF-8
LC_NUMERIC	en_US.UTF-8
LC_TIME	en_US.UTF-8

@natemcmaster Did you set them in-proc or globally on the agent?

[natemcmaster]

Globally on our Mac agents in <TeamCity Agent Home>/conf/buildagent.properties

This is finally working 😄

Looks like our new agent aspnetci-a20 is missing these variables.
