Create the package of visual web part project, AjakControlToolKit.dll is not loading into WSP or bin folder of share point site?

Hi All,

I have created an empty share point project and added a visual web part into it.

For tab control, I have used AjaxControlToolKit  and added the reference of AjaxControlToolKit.dll  in to my project.

Now whenever I create the package of the project then AjaxControlToolKit.dll  is not loading into wsp file or When I deploy the project on share point site then AjaxControlToolKit.dll is not loading in the bin folder of my share point site automatically. So manually I have to put the AjaxControlToolKit.dll  into  bin folder of share point site or GAC . But the requirement is whenever project deploys then the AjaxControlToolKit.dll should automatically load into bin folder of share point site. Right now I am doing it manually.

Note:- Even I have set.   Copy Local = True (property of AjaxControlToolKit)

How can I acheive the solution?

Thanks,

Vishwa
