@markwgit thanks for the PR. The build for PR failed. I believe .github/workflows/pullrequest.yml

should use net 8 to build

@aboo,
I changed PR to draft.
Please don't close it.

We have some issue with 2 tests after we upgrade Microsoft.AspNetCore.OData to 9.1.1
Test for example: TranslateAnyToJoin_WhenThereIsOneNestedjoinWithComplexPath

Hi @aboo ,

I tried investigate the issues with 2 tests. The issue does not related to .NET8.
Its can be reproduced just after update of Microsoft.AspNetCore.OData to 8.2.4 version.

FOr example, the Cosmos DB query in test "TranslateAnyToJoin_WhenThereIsOneNestedjoinWithComplexPath" is generated incorrectly:
Invalid query: SELECT VALUE c FROM c JOIN l IN c.payload.bet.legs JOIN o IN l.legs.outcomes WHERE o.id = 'test'
Correct query: SELECT VALUE c FROM c JOIN l IN c.payload.bet.legs JOIN o IN l.outcomes WHERE o.id = 'test'

Could you please look on this issue or may be forfard this issue to relevant person?
Thanks
