Accessing invalid version containing letters throws exception

[douglaslps]

This is my route configuration:

config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{version}/{controller}/{id}", defaults: new { id = RouteParameter.Optional } );

I don't want to use "api/v1/". I like "api/1/" better. I was testing it and if I try to access "api/x/" an exception is thrown:

An error has occurred.Specified cast is not valid.System.InvalidCastException at SDammann.WebApi.Versioning.VersionedControllerSelector.GetVersionRouteDefaults(HttpRequestMessage request) in z:\Developing\Visual Studio\Projects\SDammann.WebApi.Versioning\src\SDammann.WebApi.Versioning\VersionedControllerSelector.cs:line 155 at SDammann.WebApi.Versioning.VersionedControllerSelector.SelectController(HttpRequestMessage request) in z:\Developing\Visual Studio\Projects\SDammann.WebApi.Versioning\src\SDammann.WebApi.Versioning\VersionedControllerSelector.cs:line 118 at System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsyncCore(HttpRequestMessage request, CancellationToken cancellationToken) at System.Web.Http.Dispatcher.HttpControllerDispatcher.d__0.MoveNext()

Do you think you can fix it? IMHO returning an error saying the version wasn't find would be better.

As this is a breaking change, I prefer to postpone this for vNext.

Your eror has been fixed in vnext branch. Please check out the changes and see if you're happy with it. I have not yet finalized the documentation nor pushed a prerelease package, but based on this file you should be able to get it working.

You can now choose a prefix for versioning in the URL by specifying in the route configuration. For example: api/v{version}/{controller}.

Fantastic! Thanks.
