An item with the same key has already been added.

JTWebMan posted on Wednesday, April 02, 2008

We are running version 2.1.0 and get this error intermittently last time we deployed. Has anyone else seen this error before in the CSLA object. The stack trace stops at Csla.Security.SharedAuthorizationRules.GetManager. I am sure its not a CSLA error I just want to know what I implemented wrong.

Thanks
