ERROR AFTER CHANGING NAMESPACE OF ASP.net MVC PROJECT

Question

Recently i have changed the namespace using the project properties. After that, application was compiling successfully, but at run-time it throws error "The type or namespace name ‘sample’ could not be found (are you missing a using directive or an assembly reference?)". Error: Line 23: using System.Web.Routing; Line 24: using Sample;

Source File: c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files......\App_Web_index.cs Line:

I tried to locate the string “using Sample” and didn’t find anywhere in my solution. Tried removing the temporary files from framework folder but no luck.

The problem was with my Web.config file

<system.web.webPages.razor>
 <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
 <pages pageBaseType="System.Web.Mvc.WebViewPage">
  <namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Optimization"/>
    <add namespace="System.Web.Routing" />
    <add namespace="Sample" />
  </namespaces>
</pages>

I just replaced the old value "Sample" with new namespace name, and everything starts working again.

this may work at first, but somehow (the next times or sometimes) the old value is still cached somewhere and VS (Intelligently) uses that cached value, cannot stand this bug.
