I have a "MVC 4" project and i want to add an assembly to web.config file but i don't know where should i put it. I try any ways but i cant find the solution.
every time i got this error:
You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
this is my web.config file:

please help me.
thanks.
A configuration file (web. config) is used to manage various settings that define a website. The settings are stored in XML files that are separate from your application code. In this way you can configure settings independently from your code.
You must create a text file that is named Web. config in the root directory of your ASP.NET application. The Web. config file must be a well-formed XML document and must have a format similar to the %SystemRoot%\Microsoft.NET\Framework\%VersionNumber%\CONFIG\Machine.
Your application inherits all configuration settings from the Machine. config and Web. config files in the %SystemRoot%\Microsoft.NET\Framework\<version>\CONFIG directory, but you will not see those default settings here. Application-level or directory-level Web.
config files. The configuration files for IIS 7 and later are located in your %WinDir%\System32\Inetsrv\Config folder, and the primary configuration files are: ApplicationHost. config - This configuration file stores the settings for all your Web sites and applications.
It is quite simple. Look at your compilation section in your web.config:
<compilation debug="true" targetFramework="4.0"/>
Now open the section and put your assembly inside like this:
<compilation debug="true" targetFramework="4.0"> <assemblies> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> </assemblies> </compilation>
Libraries in this section are checked in compilation time, it has nothing to do with runtime binding.
