'jQuery' is undefined

.NET
1

Hello!
I use ASP.NET MVC 4 project.
Install package from Nuget MiniProfiler 2.1.0.
Setup in main page razor view @StackExchange.Profiling.MiniProfiler.RenderIncludes() and in Global.asax Start/Stop.
When load main page raise javascript error ‘jQuery’ is undefined.
It occurs because first load script http://localhost:62928/mini-profiler-resources/includes.js?v=xwYPDDH1blvqmxgsBweNC++H7CFU3KGQ+zFcVlJPsXw=
which contains jQuery call at 897 line ...function(){d.event.special[this]={add:h}})})(jQuery);
But JQuery loaded in next request http://localhost:62928/mini-profiler-resources/jquery.1.7.1.js?v=xwYPDDH1blvqmxgsBweNC++H7CFU3KGQ+zFcVlJPsXw=

In Visual Studio 2012 update 2 create new project: ASP.NET MVC 4 Web Application.
Add HomeController and Index view.
Via NuGet install MiniProfiler.MVC3 package.
In Index view before body tag add @StackExchange.Profiling.MiniProfiler.RenderIncludes().
Open Manage NuGet packages… -> Updates (Stable only) and click Update All button.
Rebuild solution.
Run Ctrl+F5 and get error “Line: 895 Error: ‘jQuery’ is undefined”.

Is this an IE 8 issue?
There is a fix involving wildcard mapping to aspnet_isapi.dll for IIS.
I’m not sure how to map against VS2012’s ASP.NET development server…

Good news for my development machine, I’ve resolved this problem for my ASP.NET Development Server… so far, so good…

I decided to implement MiniProfiler through an HTTP Module in my .NET web forms project, following the guidelines from here http://www.codeproject.com/Articles/246820/Using-MVC-Mini-Profiler-as-a-Http-Module.

In order to solve the exception thrown due to not loading jQuery-1.7.1.js before MiniProfiler was invoked, I added the script to the insertions from the HTTP Module, just before the insertion of the MiniProfiler.Includes().ToHtmlString().

    private string MiniProfiler_jQuery = @"<script type=""text/javascript"" src=""Scripts/jquery-1.7.1.js""></script>";

Here is my ‘Write’ method in MiniProfilerFilterStream.cs that inserts the reference:

public override void Write(byte[] buffer, int offset, int count)
{
if (!profilerHtmlRendered)
{
var responseText = Encoding.UTF8.GetString(buffer, offset, count);

            if (responseText.Contains("</body>"))
            {
                var miniProfilerHtml = MiniProfiler.RenderIncludes().ToHtmlString();
                int index = responseText.IndexOf("</body>") + 8;
                int index2 = index + MiniProfiler_jQuery.Length + 1;
                var newOutput = responseText.Insert(index, MiniProfiler_jQuery).Insert(index2, miniProfilerHtml);
                var newBytes = Encoding.UTF8.GetBytes(newOutput);

                stream.Write(newBytes, 0, newBytes.Length);
                profilerHtmlRendered = true;
                return;
            }
        }

        stream.Write(buffer, offset, count);
    }
