I was trying to create a custom testimonials module following the steps in docs.sitefinity.com/tutorial-create-a-testimonials-intra-site-module .
I have followed all the steps in this link but after installing the widget to sitefinity it is showing an error "No metadata has been registered for class 'SitefinityWebApp.Modules.Testimonials.Data.Testimonial, SitefinityWebApp, Version=10.0.6411.0, Culture=neutral, PublicKeyToken=null'. (This usually indicates, that either this class is not declared persistent or it is declared persistent but not enhanced. The class was loaded from file:///C:/Program Files (x86)/Progress/Sitefinity/Projects/Default3/bin/SitefinityWebApp.DLL.)".
Can anyone help me with this issue.
