Well I found my own answer.

After reading posts of people with similar problems I figured the problem was from the upgrade of past versions and leftover dll's in the \bin directory.  I renamed the bin directory and then copied over the \bin directory from the 4.7 install.  I then added one dll at a time until I found the one that crashed the site with the above error.

I removed DotNetNuke.Provider.Membership.SqlDataProvider.dll and the site now works.

I hope this helps someone.
