                 opts.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
             })
             .AddDataAnnotationsLocalization();

  1. Enable XML Comments
    1. Manually add the two lines in PropertyGroup below to the .csproj file:
      <PropertyGroup>
  <GenerateDocumentationFile>true</GenerateDocumentationFile>

</PropertyGroup>
    2. Add the options in the code below 
           services.AddSwaggerGen(options =>

     });
