How to resolve “The 'DesignerPackage' package did not load correctly” issue??

It was the today morning I just start preparing to do my work and opened Visual Studio. Now what I found that there was lots of popup showing the error for load fail of the designer packages respectively.

The error was “The 'DesignerPackage' package did not load correctly” and I did the following trick to solve this issue in Visual Studio 2013. If you are using an older version then look for 11.0 or 10.0 folder for this “ComponentModelCache” directory.

  1. First open windows explorer and go to “C:\Users\<your users name>\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache”.

  2. Delete all the files located in this folder after closing the visual studio.

After doing this start your visual studio and all errors went away.
