Solution :

1. Open the Web.config
2. Navigate to the “configuration\runtime\assemblyBinding\dependentAssembly” and search for below given configuration lines

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" xmlns="urn:schemas-microsoft-com:asm.v1" />
    <bindingRedirect oldVersion="1.0.0.0-5.2.0.0" newVersion="5.2.0.0" xmlns="urn:schemas-microsoft-com:asm.v1" />
</dependentAssembly>

3. Replace the olderVersion value to “1.0.0.0-5.2.0.0” (this does the trick)

4. change the version of the new assembly i.e. newVersion value to “5.2.0.0”

As a good practice you may also need to update assembly version number at “system.web\compilation\assemblies” for the System.Web.Mvc
