Been using Bootstrapper_Initialized in our global.asax to use some of our own custom routes to go along side sitefinity's.
been working great for the past year or so, but its broken today after 5.1 upgrade.
We're doing whats almost identical on this thread:
error we are receiving after 5.1 upgrade is:
var routes = (System.Web.Routing.RouteCollection)args.Data;
Unable to cast object of type 'System.Linq.EnumerableQuery`1[System.Web.Routing.RouteBase]' to type 'System.Web.Routing.RouteCollection'.
any advice is appreciated
