Expected results: "Dictionary Count: 3" is displayed
Actual results: "Dictionary Count: 0" is displayed

Reproducible with: 2020.3.45f1, 2023.1.0a26, 2023.1.0b4, 2023.2.0a2
Not reproducible with: 2021.3.18f1, 2022.2.7f1, 2023.1.0a25

  1. Resolution Note:

    This is not a bug. This code is doing reflection based serialization. Managed Code stripping cannot track reflection based serialization. The package code must be annotated.

    The `[RequiredMember]` attribute is useful here. The following fixes this code.

    ```
    public class AuthorizationCodeRequest
    {
    [DataMember(Name = "response_type", IsRequired = true)]
    public string responseType
    {
    [RequiredMember]
    get

    { return "code"; }
    }

    [DataMember(Name = "client_id", IsRequired = true)]
    public string clientId

    { [RequiredMember] get; [RequiredMember] set; }

    [DataMember(Name = "redirect_uri")]
    public string redirectUri { [RequiredMember] get; [RequiredMember] set; }
    }
    ```
