I am trying to create a layout file as outlined as in this document docs.sitefinity.com/feather-create-layout-files

After following steps 1-6 have the new template appear in the templates list for the project

But when I click on the template page I get the following error ... is there something else to be done ?

(I have Feather enabled for the project)

Hi,
It is not entirely clear to me when exactly you are getting this error, when opening in Visual Studio or selecting it whilst creating a new page in the Sitefinity backend ?

cfr. my sample: http://screencast.com/t/Va71d0D4Q

I did notice that you have a folder "MVC" under "MVC".
Could you maybe upload a screenshot of where you are getting this error ?

my bad .... once the layout was created in the MVC project and re-building the project - I was going to the newly added layout via Design/Page templates - where it was listed but I would get a run-time error when I clicked the "feather layout template" (possibly because it was a template in the VS project)

However if I create a page and then select the new template it works
