Unable to add the Custom Pipeline component in to the Visual Studio Tool Box

I have
Added .dll file in to the Global Assembly Cache (use gacutil)
Copied it the Pipeline Components folder (E:\Program Files (x86)\Microsoft BizTalk Server 2013\Pipeline Components)
Everything was successful, when I try to add the component to the Toolbox I get the message like below and cannot find the component in Toolbox.
Tried several times but still getting stuck in the same place. I am using Visual Studio 2013. Any help is greatly appreciated.

Do not put the Assembly in the %\Pipeline Components folder.  Pipeline Component Assemblies should be in the GAC only.
To correctly deploy a custom Pipeline Component, you can follow the steps in this Wiki Article:
http://social.technet.microsoft.com/wiki/contents/articles/26404.biztalk-deploying-custom-pipeline-components-in-biztalk-server-2006-and-higher.aspx
I have never seen that specific error before.  Are you sure you're browsing from the Pipeline Components tab?
