OData queries give 404 error unless I add a trailing slash - iis

Question

I created a dummy project to test Odata in VS2015 and I was having an exactly the same issue as described in this question, and my code is largely equivalent to what is described there.
Web API 2: OData 4: Actions returning 404
Any query to a bound function gives a 404 error until you add a trailing slash. For example:
http://localhost:46092/odata/v1/Trips/Default.GetTripNameById - 404
http://localhost:46092/odata/v1/Trips/Default.GetTripNameById/ - works as expected
http://localhost:46092/odata/v1/Trips/Default.GetTripNameById(tripID=1)?$select=Name - 404
http://localhost:46092/odata/v1/Trips/Default.GetTripNameById(tripID=1)/?$select=Name - works as expected
This is not supposed to happen because Microsoft documentation never mentions that a trailing slash is required, their examples are supposed to work without them. Also, this breaks the Swagger UI which doesn't add a trailing slash and gets 404 when trying to make any query.
What could be the reason for this behaviour? How do I make it work without a slash, which seems to be the normal expected behaviour?
Here are my code snippets:
TripsController.cs:
...
[HttpGet]
public IHttpActionResult GetTripNameById(int tripID)
{
return Ok(DemoDataSources.Instance.Trips.AsQueryable().Where(t => t.ID == tripID.ToString()));
}
WebApiConfig.cs:
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.MapODataServiceRoute("odata", "odata/v1", GetEdmModel());
DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));
config.EnsureInitialized();
}
private static IEdmModel GetEdmModel()
{
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Person>("People");
builder.EntitySet<Trip>("Trips");
builder.EntityType<Trip>().Collection.Function("GetTripNameById").Returns<string>().Parameter<int>("tripID");
var edmModel = builder.GetEdmModel();
return edmModel;
}

It turns out that the Web.debug.config is actually ignored by Visual Studio.
After adding this code to web.config, everything works:
<system.webServer>
<handlers>
<!-- the following line is required for correct handling of dots in URLs-->
<add name="ApiURIs-ISAPI-Integrated-4.0"
path="/odata/*"
verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS"
type="System.Web.Handlers.TransferRequestHandler"
preCondition="integratedMode,runtimeVersionv4.0" />
<!-- end line for handling of dots-->
</handlers>
</system.webServer>
