This issue is resolved by the following steps -
1) Close all instances of VISUAL STUDIO at startup and open one instance of Visual Studio
2) Close the solution (nothing but your project). If it is already open, then it will open again
3) Clean the entire project and rebuild it.
4), and also create a project if you get any errors, such as "___. Dll not found"
