Followed the instructions on github.com/.../Create-a-“Hello-World”-MVC-widget-in-a-separate-assembly with no success. Also, did not change the name of the SitefinityWebApp project.
Is this a known bug with Feather?!
Many thanks for your help, Velizar.
It turns out that the nuget package for Telerik.Sitefinity.Feather.Core in the separate assembly was a different version to the main web site project. It's working fine now.
My mistake, it's still not working. I have tried all these steps and it still does not register. The assembly dll existing in the web site bin folder, I used reflector and the views are definately embedded.
I tried to manually edit the ToolboxesConfig.config file and although it appears, I get an error - The file '/MVC/Views/Test/Index.cshtml' does not exist.
Any other ideas would be greatly appreciated.
