[BUG]: C# Not Generating [JsonRequired] or [Required] Annotation

[cawoodm]

With CSharp, required properties are not annotated as such:

Indeed the "Fail if required properties are missing" option seems to do nothing.

Current Output

[JsonPropertyName("vatCode")]
public string VatCode { get; set; }

Expected Output:

[JsonRequired]
[JsonPropertyName("vatCode")]
public string VatCode { get; set; }
