Answer 1

I had a multi-project solution and was installing it from the Package Manager Console. I found that installing it using the following command worked:

 PM> Install-Package -ProjectName <MyProject> Glimpse.MVC4

Of course you need to replace <MyProject> with your own project name.

Make sure you have the Glimpse module and handler registered in your web.config based on the web server you are using.

• If you are using a site on IIS6, in IIS7.x classic pipeline mode or Visual Studio Development Server

  <system.web>
      <httpModules>
          <add 
              name="Glimpse" 
              type="Glimpse.Core.Module, Glimpse.Core"
          />
      </httpModules>
      <httpHandlers>
          <add 
              path="glimpse.axd" 
              verb="GET,POST" 
              type="Glimpse.Core.Handler, Glimpse.Core"
          />
     </httpHandlers>
     ...
  

• And if you are using IIS 7.x in integrated pipeline mode or IIS Express:

  <system.webServer>
      <modules>
          <add 
              name="Glimpse" 
              type="Glimpse.Core.Module, Glimpse.Core" 
              preCondition="integratedMode" 
          />
      </modules>
      <handlers>
          <add 
              name="Glimpse" 
              path="glimpse.axd" 
              verb="GET,POST" 
              type="Glimpse.Core.Handler, Glimpse.Core" 
              preCondition="integratedMode" 
          />
      </handlers>
      ...
  </system.webServer>

I encountered the same problem and in my case the solution was to add the following code to Application_Start() in the MvcApplication class:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

Answer 4

I have had a very similar problem, and none of these options helped me, but I did get it working. This is what I had to do:

I am using MVC 5, so make sure you have read the latest config for glimpse for the version you are using. I should have been using Glimpse.AspNet and not Glimpse.Core

My web config looks like this:

 <handlers>
    ....
    <remove name="Glimpse" />
    <add name="Glimpse" path="glimpse.axd" verb="GET"
         type="Glimpse.AspNet.HttpHandler, Glimpse.AspNet"   
         preCondition="integratedMode" />  
</handlers>
<modules>
    ....
    <remove name="Glimpse" />
    <add name="Glimpse" 
         type="Glimpse.AspNet.HttpModule, Glimpse.AspNet" 
         preCondition="integratedMode"/>    
</modules>

I am using IIS Express, Vs2015 and for some reason my C:\Users\me\Documents\IISExpress\config\applicationhost.config got messed up, and had a special entry for Glimpse.

So I found and removed any entries with Glimpse in them (carefully, you might want to comment them out instead)

<application path="/Glimpse.axd" applicationPool="Clr4IntegratedAppPool">
    <virtualDirectory path="/" physicalPath="\path\to\extra\website" />
</application>

I think this may have happened from a really early version of glimpse been installed, and also something to do with the upgrade to MVC5, but not 100% sure why...

Hope this helps someone else.

Answer 5

In my case, the web app is not deployed in root, so the url is:

http://localhost:54026/MyApp/glimpse.axd

Very obvious, but I'll leave this answer as a reminder.
