Array of enums in a request generates code (C#) that produces a compile error

[hervala]

What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Nuget tool

Client library/SDK language

Csharp

Describe the bug

With an OpenAPI description that has a route with request body of enum array. Kiota will generate a C# client that has a compile error:

Error CS1061 : 'RequestInformation' does not contain a definition for 'SetContentFromEnumCollection' and no accessible extension method 'SetContentFromEnumCollection' accepting a first argument of type 'RequestInformation' could be found (are you missing a using directive or an assembly reference?)

RequestInformation type has a method SetContentFromEnum but not the needed SetContentFromEnumCollection

Expected behavior

Kiota should generate code that compiles.

How to reproduce

Problem can be reproduced by generating a C# client with the provided Open API description. Command used to generate the client was:

dotnet kiota generate -l CSharp -c Client -n ConsoleApp1 --openapi example.yaml -o ./Client
