I have created a custom mvc page template in external assembly as custompagetemplate.cshtml and changed its BuildAction property to Embedded
Resource and made the entry in AssemblyInfo.cs.... But the template is not registered (it is not available in Sitefinity's Backend under Design/Page Templates).
I have gone through a link http://www.sitefinity.com/developer-network/knowledge-base/details/sitefinity-cannot-find-template-created-in-an-external-assembly
and I have made the virtual path entry but still facing the same issue.


The
Mvcfolders are meant for custom MVC Widgets. Sitefinity MVC (feather) uses theResourcePackagesfolder for out-of-the-box widgets and layouts.If you move your layout file to
/ResourcePackages/Bootstrap/MVC/Views/Layoutsit will automatically be added to the Page Design overview in Sitefinity Backend.
