Question

I’ve having a heck of a time figuring out why my routing configuration isn’t work. I tried mysite/issues/500 and mysite/issues/ but i always get a 404 error. I put a breakpoint in both the get functions and it never hits the breakpoint. Thought maybe glimpse could help me but i tried to

Here is my global.asax:

    Public Class MvcApplication
    Inherits System.Web.HttpApplication

    Sub Application_Start()
        AreaRegistration.RegisterAllAreas()
        RouteTable.Routes.MapRoute("Issues", "{controller}/{id}", New With {.id = UrlParameter.Optional})
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters)
        RouteConfig.RegisterRoutes(RouteTable.Routes)
    End Sub
End Class

Controller:

Namespace Controllers


    Public Class IssuesController
        Inherits ApiController

        ' GET api/issues'
        Public Function GetValues(ByVal req As HttpRequestmessage) As IEnumerable(Of Issue)
            Dim querystrParams As NameValueCollection = Nothing
            Dim srch As IQuery
            If req.RequestUri.Query.Any() Then
                srch = New IssueTrackerQuery(req.RequestUri.ParseQueryString())
            End If
            Return (New EnumerableQuery(Of Issue)(New HashSet(Of Issue)))
        End Function

        ' GET api/issues/5'
        Public Function GetValue(ByVal IssuesId As Integer) As Issue
            Return New Issue()
        End Function

        ' POST api/issues'
        Public Sub PostValue(ByVal value As String)
            Throw New NotImplementedException()
        End Sub

        ' PUT api/issues/5'
        Public Sub PutValue(ByVal id As Integer, ByVal value As String)
            Throw New NotImplementedException()
        End Sub

        ' DELETE api/issues/5'
        Public Sub DeleteValue(ByVal IssuesId As Integer)
            Throw New NotImplementedException()
        End Sub

    End Class
End Namespace

You don’t have any API routes in your Global.asax. Add one using the MapHttpRoute extension method (instead of MapRoute):

Sub Application_Start()
    AreaRegistration.RegisterAllAreas()
    RouteTable.Routes.MapHttpRoute("Issues", "{controller}/{id}", New With {.id = UrlParameter.Optional})
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters)
    RouteConfig.RegisterRoutes(RouteTable.Routes)
End Sub

Notice the routes.MapHttpRoute which registers the web api controllers.
