Getting 404 not found on IIS server when I run site locally - asp.net-mvc-4

Question

I updated MVC3 to MVC4, since then I get lots of problems when I try to upload new version on iis servers
if for example I will change reference to dll in web.config to be the previous one for example System.Web.Helpers
from 2.0.0.0 to 1.0.0.0 I will get Server Error in '/' Application. if I have a look in event viewer I can see that the problem is Could not load file or assembly 'System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. which is right. but when I fix it I get 404 and I totally not understand why. The resource I'm looking for has not been removed, had its name was not changed, and is available.
this is my web.config
<?xml version="1.0" encoding="utf-8"?>

when I try to change version of MVC4 dll in web.config to the previous version of MVC3 i get an error regarding it that it couldn't find assembly with version x and it's right. when I fixe it I expect to get successfully run, but eventually I get 404 not found

Answer 1

There are many reasons for this error, you can try the following methods to solve the problem:
Try to remove all binding redirect: bindingRedirect oldVersion="" newVersion="" />
Change the .NET CLR version to v4.0.
If it still doesn't work, please make sure the version of the dependencies of the current project is correct.

Answer 2

actually I found the solution after so many hours of investigation.
I had to remove the PrecompiledApp file from the project folder.
