Custom Page Template in external assembly

I have created a custom mvc page template in external assembly as custompagetemplate.cshtml and changed its Build Action property to Embedded Resource and made the entry in AssemblyInfo.cs.    But the template is not registered (it is not available in Sitefinity's Back-end under Design/Page Templates).
I have gone through a link  www.sitefinity.com/.../sitefinity-cannot-find-template-created-in-an-external-assembly   and I have made the virtual path entry but still facing the same issue. Is there is any other way of doing it.
