What causing this error. I have 2 different page(.aspx) in one website. For the first page, i use using Facebook and doesn't have any error in this first page.

But for another new .aspx page. i using the using Facebook for reference but getting this error:

The type 'Facebook' in 'C:\Users\Documents\VS2010\Websites\Test\FacebookIntegration.aspx' conflicts with the imported namespace 'Facebook' in 'C:\Users\Documents\VS2010\Websites\Test\Bin\Facebook.dll. Using the type defined in 'C:\Users\Documents\VS2010\Websites\Test\FacebookIntegration.aspx'.

can someone please tell me why this is happen? Thank in advance.

Answer 1

Do you have a class named Facebook , and a namespace called Facebook ? If so, that's a problem. You should rename your class to something else, preferably something more descriptive. If you end up with two third party products, rename both of them using an alias .

I'm guessing you have a page called FacebookIntegration.aspx, but maybe you originally called it Facebook.aspx and so the class name ended up being Facebook and you just need to rename it, probably make it match the file name.
