After upgrading to Dev version 2.0.17, the designer is showing : “value cannot be null : parameter name instance”
Reversing to 2.0.13 solves the problem.
I solved the problem with copy new web.config from rebuild project replace old file in IIS.
what kind of form/page are you opening in the designer ?
Any chance to create a test app for us and send it to frankATiceteagroup.com ?
Thanks in advance !
