I just have a question here... Why is the enum not there in the first place? I'm confused?!

@sebastienlevert I believe the fix here is made to align with other languages.

Essentially, the scenario here is when the API is updated, and your production code is running a certain version of a generated SDK. If the API starts returning a new value in the enumeration, your code should not start breaking due to exceptions/errors being thrown and break the application. Instead, the Enum property should be set to the default (null) till the time you update your code to handle the new value.

Do we need a version bump/changelog entry? and possibly tests similar to https://github.com/microsoft/kiota-serialization-json-dotnet/blob/99db4c2d27af5846207794390b4d8e935b1e6472/Microsoft.Kiota.Serialization.Json.Tests/JsonParseNodeTests.cs#L125
