Guy,

I have done a search of the entire project and all my references are correctly listet as version 3.6. As I mentioned to TIm, if I had an invalid reference in my web.config, I would be geting a build error which I am not.

It appears that the reference is somewhere in temporary code that gets generated at run time. It looks like the AppCode folder which runs the UserManager code seems to be the culprit, but I have yet to determine exactly where.

With regard to updating these framework references, I went to the references section of the Project Explorer (for each project, e.g., Business objects project, WFP app project) and removed the prior MM framework references and added in the same references for the new version.

>>I have put the stack trace below. It looks like a temporary file somewhere is getting generated and is referencing the old version of the framework (3.5). I have searched for any references to this version 3.5 file but I come up empty. Is there something I need to purge or clean up that would fix this issue.
