using IncludeXmlCommentsWithRemarks does not include XML docs for DTO properties

[ci-vamp]

i have tried debugging this and cant get to the bottom of it.

i have a DTO like this for example:

using Common.Annotations;

namespace API.DTO.Training
{
    public class Example
    {

        /// <summary>
        ///     This documentation is NOT included
        /// </summary>
        public CustomClassType SingleCustomClass { get; set; }

        /// <summary>
        ///     This documentation is included
        /// </summary>
        public List<CustomClassType> EnumerableCustomClass { get; set; }

        /// <summary>
        ///     This documentation is included
        /// </summary>
        public bool SingleSystemType { get; set; }
    }
}

comments that appear as description in the schema:

• a system type (string, bool etc)
  • single or an enumerable
• a custom type (a class i define) if it is a list / enumerable type
• only for enumerable

comments that do not appear as description in schema:

• a custom type (a class i define) if it is a singular property

any idea what can be causing this? i tried debugging down to the XmlCommentsWithRemarksSchemaFilter class and these properties never show up when the filter is being applied
