Latests generation at https://dev.azure.com/microsoftgraph/Graph%20Developer%20Experiences/_build/results?buildId=130660&view=logs&j=0c914960-8b50-5299-c9aa-dd3c9595168e&t=97dbd468-8cc6-5acc-f2af-de93eaf8bad9 fails due to changes in #3921

Referenced types of enum in an anyOf or array are incorrectly generated as inline types.

e.g. the reason property is generated as RejectPostRequestBody_reason.cs rather than a collection of micrososft.graph.rejectedReasons

Hi @andrueastman,
Thanks for reporting this.
Why would you expect the reason property to be a collection? It's not described as an array.
The fact that the type is getting inlined because of the change is concerning though.

Thanks for clearing this up @baywet. The issue does seem to be with inlining.
I made the mistake of thinking it had to do with collections due to other examples I was looking at that met the criteria such as
acceptedModalities here.
