I just ran into the same problem, and the culprit was my uninstalling of Visual Studio Express 2012. (Possible that it might be any version of VS2012.) My overall order of operations was:

• Installed Visual Studio Express 2012 (long time ago)
• Used Visual Studio Express 2012 happily for many months
• Installed Visual Studio 2013 Premium
• Used Visual Studio 2013 Premium happily for weeks
• Uninstalled Visual Studio Express 2012
• ERROR

I'm not 100% certain on the cause of it, or what combinations of VS 2012/2013 would exhibit this behavior. But the solution for me was to edit the root web.config files in the framework directories:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config

And remove the lines:

<remove assembly="Microsoft.VisualStudio.Web.PageInspector.Loader, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add assembly="Microsoft.VisualStudio.Web.PageInspector.Loader, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

This resolved the issue for me.

回答2:

No need to remove those lines
Just close and reopen the Visual studio with Admin privileges.

I got the same problem but not on my development machine but on hosting server.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config

I was able to fix it by adding below code to my web.config

<compilation targetFramework="4.5"> 
    <assemblies> 
        <remove assembly="Microsoft.VisualStudio.Web.PageInspector.Loader,
    Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </assemblies> 
</compilation>

or by removing reference to this assembly from web.config files in framework directories.

I never installed VS there and i never had PageInspector installed there. Any idea why those configs reference them?

For those who might end up here, try removing the following line in the Web.Config file of your Project while debugging <identity impersonate="true" userName="blah" password="blah">

It took time until I finally came across the following thread: Could not load file or assembly or one of its dependencies. Access is denied. The issue is random, but after it happens once, it continues

回答5:

I've ran into this error while trying to run an ASP.NET project in VS2013 after having uninstalled a VS2015 preview. Repairing the VS2013 installation seems to have solved the problem.

回答6:

I removed the dll from gac and it started working. I am not sure where those dlls came from. If you have 2 or more versions of visual studio, reinstall the last version.

回答7:

Try updating your Microsoft.ApplicationInsights nuget package. This also installs other dependencies. I ran into this problem when I had to change my Target Framework.

1. Tools > NuGet Package Manager > Manage NuGet Packages for Solution...
2. search for "applicationinsights"

or run

Install-Package Microsoft.ApplicationInsights

Had a similar problem (another assembly) and for me it was a missing line in the web.config on the machine. A line that I think lets the web server load (any?) dll. I had to add "*" to the compilation-assemblies list in the web.config:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config

Like this

    <compilation>
      <assemblies>
        ...
        <add assembly="*" />
      </assemblies>
    </compilation>

To find it I had to compare the file with one from a working server. So it seems to me that It really is a load failure, but to determine why it fails, we need to be Sherlook H.. Normally I use a tool like ProcessMonitor to find out why I get a Load Failure, but this time, of course, it gave me no useful output.. IIS never tried to load the assembly!

If you don't see web.config in both of paths: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config

file "Web" is in "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\" what I really want to show you, It's Web.config, you should open it with: notepad++... and remove:

//" I finish my problem with them.

回答10:

it solved the problem on at my end by applying the approved solution in this thread.

modifying the following two files, and removing Microsoft.VisualStudio.Web.PageInspector.Loader resolved the issue.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
