JsonConverter applied to an enum property is not respected

[sherlock1982]

I'm using Swashbuckle.AspNetCore and Swashbuckle.AspNetCore.Newtonsoft 5.6.3. Consider the following example:

public enum LicenseInfoReceivingStatus
{
    Success,
    OtherError,
}

public class LicenseFqdnInfo
{
    [JsonConverter(typeof(StringEnumConverter))]
    public LicenseInfoReceivingStatus Status { get; set; }
}

In this case Newtonsoft.Json will serialize this enum as string. Swashbuckle current behavior: In schema it will be reported as int enum

Swashbuckle expected behavior: In schema to be reported as string enum

As a workaround i can apply [JsonConverter(typeof(StringEnumConverter))] to a type itself but this is not correct in all cases. Another workaround will be to DescribeAllEnumsAsStrings() and this is also not always correct.

Looks like this may be a duplicate of https://github.com/domaindrivendev/Swashbuckle.AspNetCore/issues/1459?

You're halfway there by installing Swashbuckle.AspNetCore.Newtonsoft.

You also need to add this line in your startup:

services.AddSwaggerGenNewtonsoftSupport();

Check the docs here for more details:
