@reddyashish it looks like your 5th and 6th commits are not in chronological order. Did you come across any conflicts?

We need to be careful that no other changes have gone into these files outside of these cherry-picks.

Have you run self-serve on this PR?

[reddyashish]

@aparajit-pratap, the self serve has no regressions. The 5th and 6th commits are related to a one task(infinite loop bug) and the changes are made to different files compared to the other 4 commits. So there were no conflicts there.

[reddyashish]

Removed the DsCoreDataTests file as this was introduced by a different PR https://github.com/DynamoDS/Dynamo/commits/master/test/DynamoCoreTests/DSCoreDataTests.cs.

The changes to this file, that were done by this PR(#9388) are being ignored.

LGTM!

@saintentropy Since we will have daily build after this change, does it make sense for Black Team to also consume this build early and play with it? I expect installer change required still on your end to install Refinery on Dynamo 2.0.3 OOTB. Please check.
