Description

Is your feature request related to a problem? Please describe.

The method parameter type for schema type array is a csharp List. A more generic approach would be, to use IEnumerable.
This makes working with the API easier, if you have other containers than lists.
Also it makes working with F# easier, because F# containers are compatible with IEnumerable, but for List I need to cast.

Describe the solution you'd like

Use IEnumerable for schema type array in Api methods.

Describe alternatives you've considered

Otherwise there is a lot of casting when using any other container than List, or in F#.

Research direction

Locate the C# generator templates and generated API method signatures for schema type arrays, then inspect how those signatures are validated. Done means generated API methods use IEnumerable instead of List for these parameters while remaining compatible with other containers and F# callers.
