If you want to convert your application from mvc 2 to mvc 3 follow instruction from here or you may get help from here

@mola, message "Could not load type 'System.Web.Mvc.ViewPage'" says that your project doesn't see "System.Web.Mvc.dll" library.

Check in root web.config file next section:

<configuration>

  <system.web>

    <compilation debug="true" targetFramework="4.0">
      <assemblies>
        <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      </assemblies>
    </compilation>

  </system.web>

</configuration>

Also verify that you have installed MVC 3 dll. You can check existance of file "System.Web.Mvc.dll" in directory "C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies\"
