Sharepoint 2007 to 2010 reference dll help!

Hello All -

We are in the process of upgrading from moss 2007 to 2010.

I have visual studio 2010 (using C#) and i created a blank website.

When i go to view the website i get an error saying
"Could not load file or assembly 'Microsoft.SharePoint.Portal.SingleSignon, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified."

I'm not sure where i have this reference. It's not in my web.config file. I didn't manually add any references either.

I understand 'Microsoft.SharePoint.Portal.SingleSignon is no longer being used in 2010.
I'm just looking to remove any reference to it.

Any help. Am I leaving out any other information that could help?
