I use this code to add version on .net freamwork 4.6.2:

Asp.Versioning.WebApi : 7.0.0
Asp.Versioning.WebApi.ApiExplorer : 7.0.0

config:

config.MapHttpAttributeRoutes();
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/v{apiVersion}/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
            config.AddApiVersioning(options =>
                {
                    options.ReportApiVersions = true;
                    options.AssumeDefaultVersionWhenUnspecified = true;
                    options.Conventions.Add(new VersionByNamespaceConvention());
                    options.DefaultApiVersion = new ApiVersion(1, 0);
                    options.ApiVersionReader = ApiVersionReader.Combine(
                        new UrlSegmentApiVersionReader(),
                        new HeaderApiVersionReader("x-api-version"),
                        new MediaTypeApiVersionReader("x-api-version"));
                }
            );
SwaggerConfig.Register(config);

controller

[HandleError]
    [ApiVersion("1")]
    [System.Web.Http.AllowAnonymous]
    [Route("api/v{version:apiVersion}/[controller]/[action]")]
    public class BaseController : ApiController
    {
}

[ApiVersion("1")]
public class CustomerController : BaseController
{
}

but when call api method like this, I get error:

http://localhost:63593/api/v1/Customer/GetErrors?userCode=1

Thanks for contacting us. This seems to be a question about the ASP.NET Core API Versioning library. Please file an issue over there as this is probably caused by a change in their APIs.
