Why are these asserts being removed as part of enabling CI?

These asserts are wrong, they were not being tested earlier because contracts.Assert was being removed.

LGTM for the yml changes and script changes.

Disabling these tests on netcoreapp3.0 feels wrong. What happens when we completely move to .NET Core 3.0? We will then have to spend effort on re-enabling these tests for 3.0.
Is there a way we can investigate why the baselines differ? Rather than just shutting the tests off?

I am working on investigating the failures on netcoreapp3.0
I was able to fix some more tests in the aligned Array PR,
I have an issue open with the list of those tests. but we may require some more people to work on it.

@eerhardt can you take another look ? |

What are we doing to track getting these tests enabled on .net core 3?

i have opened the issue for it #1096
It contains the list of tests that we fixed and ones still remaining

Release build is still failing |
it is due to this change #1724 |

I think asserts here are still valuable, aren't they?
Contracts.Assert(count <= src.Length && src.Length <= dst.Length);

I will add the more appropiate asserts with the documentation pr.
I am thinking of an another approach of slicing the span to the required length before passing to these functions and adding the contracts.Assert(src.Length == dst.Length) . Is this approach worth doing ?

IMO - no I don't think that approach is worth doing. That's why the count parameter is passed to these functions - so the spans don't need to be the same length, and one of the spans isn't chosen as "the one with the right length". It's unnecessary logic to ensure the spans are the same length.
Slicing spans is cheap, but it isn't free. You still have bounds checks to ensure the sliced values are less than the span length.
