Hi,
I am working on nopcommerce project and trying to develop new features to my own shop at my local machine. Nopcommerce suddenly started to display this error at website's Homepage. My development is not related with Customer table or it's entities. I can't trace exception's source. Please help.
"An unhandled exception occurred while processing the request.
InvalidOperationException: The property 'Id' on entity type 'Customer' has a temporary value while attempting to change the entity's state to 'Unchanged'. Either set a permanent value explicitly or ensure that the database is configured to generate values for this property.
