Swagger Query Parameter name prefix

[ssghoda]

I have a Request class as follows:

public class GetCareTypesRequest
    {
        /// <summary>Tpa Partition</summary>
        [Required]
        public string TpaPartition { get; set; }
    }

I am passing entire object as a single query parameter instead of individual in Controller method as follows:

public async Task<IHttpActionResult> Get([FromUri] GetCareTypesRequest request) {}

When I go to Swagger page, I am seeing "request" as a prefix for TpaPartition parameter:

Even Request URI is coming as: http://localhost:52354/api/CareTypes?request.tpaPartition=0000010000010001

I am expecting it to be like: http://localhost:52354/api/CareTypes?tpaPartition=0000010000010001 and I still want to send entire object as a single query parameter.

What should I do to achieve this? I came across few articles which suggest to create a custom Filter but any easy way would be very helpful.
