StackExchange MiniProfiler UrlRoutingModules does not implement IHttpHandlerFactory

Question

Miniprofiler on my site has stopped working. In Chrome console, I get a 500 error on:

/mini-profiler-resources/includes.js?v=4.0.0.0

The error is:

Server Error in '/' Application.

System.Web.Routing.UrlRoutingModule does not implement IHttpHandlerFactory or IHttpHandler.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

My web.config file has the following relevant lines:

  <system.webServer>
    <handlers>
      <add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
    </handlers>
    <modules>
      <add name="DynamicURLRewrite" type="C3.Code.Controls.Application.Rewriting.URLRewriter" />
      <remove name="TelemetryCorrelationHttpModule" />
      <add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" preCondition="integratedMode,managedHandler" />
      <remove name="ApplicationInsightsWebTracking" />
      <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" />
    </modules>

What is the value for runAllManagedModulesForAllRequests in your web.config? – Zahara

What version of IIS are you running? support.microsoft.com/en-us/help/980368/… – Airiness

@TarunLalwani that key is not specified in my web.config – Oloughlin

@OluwafemiSule also cannot install the hotfix, "The certificate for the signer of the message is invalid or not found" – Oloughlin

Please add below

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer> 

To web.config and see if it helps? If that doesn't work then check if you are able to access the files using localhost

http://127.0.0.1:<port>/mini-profiler-resources/includes.js?‌​v=4.0.0.0

If nothing works give uninstall and reinstalling MiniProfiler also a shot. Sometime re-installations do wonders

Can you check if http://127.0.0.1:<port>/mini-profiler-resources/includes.js?v=4.0.0.0 works? Use the port configured – Zahara

See if this helps ? https://mcmap.net/q/1628591/-mvc-mini-profiler-1-4-amp-iis – Zahara

Unfortunately not – Oloughlin

Reinstalled Miniprofiler and got it working again now. Not sure why that fixed it. IF you want to edit your answer to suggest uninstall/reinstall I'll mark it as correct as you tried to help :) – Oloughlin

@TomGullen, glad it works for you now :-). Answer updated – Zahara
