This is my configuration for the Web API in App_Start/WebApiConfig.cs:
public static void Register(HttpConfiguration config)
{
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);.....
And this is my global.asax class:
GlobalConfiguration.Configure(WebApiConfig.Register);
But whenever the application is starting, I get this exception:
The route template separator character '/' cannot appear consecutively. It must be separated by either a parameter or a literal value

This is how I am using attribute routing on my controller:
[RoutePrefix("v1")]
public class MarketController : ApiController
{
[HttpGet]
[Route("/marketdata/tickerinfo")]
public IHttpActionResult TickerInfo(string currencyPair)
{
The reason for the above error is that I am using an additional '/' in the route attribute for the action. The action defined in the above controller should be as follows:
[HttpGet]
[Route("marketdata/tickerinfo")]
public IHttpActionResult TickerInfo(string currencyPair)
{
