I am new to SharePoint 2013. I am using SharePoint 2013 server and vs 2010.

The SharePoint Server 2013 and VS2010 is present on different PC's. I have created a new "Hello" visual web-part in vs 2010 using "WSPBuilder". I have just added a "Hello" text to web-part and I try to upload the web-part to my site and getting the error as below:

"Cannot import hello web part"

Can any one help to solve this problem.
