May 26, 2023 by Tarik

You could add the following handler to the <handlers> section of your <system.webServer>: <add name=”ManagedDllExtension” path=”api/nav/*/*.dll” verb=”GET” type=”System.Web.Handlers.TransferRequestHandler” preCondition=”integratedMode,runtimeVersionv4.0″ /> This will make all requests containing .dll be served through the managed pipeline.

What is routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”)

May 8, 2023 by Tarik

.axd files don’t exist physically. ASP.NET uses URLs with .axd extensions (ScriptResource.axd and WebResource.axd) internally, and they are handled by an HttpHandler.
