thanks for the video..i am quiet new to sharepoint and so i just followed the video to create my wep parts..however when i try to deploy my web parts i got this message and  error:

"Load of property 'OutputPath' failed. The entered path is not a valid output path"

"System.NullReferenceException: object reference not set to an instance of an object."

i have set my output path to the bin folder..and also i have tried the suggestions written here..but still having the same error..

any suggestion is welcomed!
