After Installing UR13 I cannot export the complete Entity Definition anymore. The <FormXml> part is missing completely. I have an application that exports an Entity as unmanaged, then adds new Controls to the <FormXml> and then reimports the entity to CRM. Now all of that is not working because the Form Definition will not be exported at all. This happens for both Managed and Unmanaged Solutions.
Does anyone knows if this is a bug and if there is any way to solve it?
