Error:

System.IO.FileNotFoundException: Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified

Solution:

• Remove the MVC reference and add the correct reference to the project
• Change the Copy Local property of the reference to true
• Update the bindingRedirect setting in web.config as below

web.config runtime section:

<runtime>

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<dependentAssembly>

<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />

<bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.1" />

</dependentAssembly>

Change the Copy Local setting will include the System.Web.MVC.dll file in the bin folder when you publish the project, so that it works even if the server is not updated with the new version.
