MVC-only pages & page headers
I am looking at moving our content over to MVC-only pages mostly to use the Kendou UI MVC tools that we purchased. The biggest problem that I cannot find a solution for is being able to modify the <head> section of a MVC-only page. It seems that for these "pure" type of pages, Sitefinity is ignoring the "HTML included in the <head> tag (except title, keywords, description)" section in Page Title and Properties. (I hope that this is a bug that will be fixed.)
Digging around the Telerik.Sitefinity.dll file I think that MVC-only pages are rendered using the Telerik.Sitefinity.Mvc.Rendering.PureMvcPageResolver() class. There is a string in there called DefaultFrontendPageTemplate that points to an aspx page that I think is the basis for all MVC only pages. The file is called "Telerik.Sitefinity.Resources.Pages.FrontendMvc.aspx and is embedded in the Telerik.Sitefinity.Resources.dll file. Is there a way to override that string to point to a custom aspx page that can essentially serve as a master page for MVC-only pages?
I considered MVC Layouts but I cannot find a way to modify the <head> section of the rendered page because the MVC widgets are rendered later in the page life cycle after the head tag has been created.
This is a known issue. You cannot add anything to the <head> tag in a Pure MVC page for the time being. You currently cannot change the DefaultFrontendPageTemplate either.
There is a solution planned for 5.2 that will let you include HTML in the <head> tag by using a section.
We are sorry for the caused inconvenience.

I see that 5.2 has been released however the change log does not mention any changes the Sitefinity implementation of MVC. Did this fix make it into the 5.2 build of Sitefinity? If not, I really need a workaround to be able to modify the <head> tag of an MVC only page template.
We could not get this feature ready for the release but it will be included in the service pack.
We are terribly sorry for any inconvenience that this delay might cause you.
the Telerik team
was this ever completed in any existing release?
We have fixed the problem and the fix will be included in our upcoming release Sitefinity 6.1. Fixing the problem required more development time, because we have another problem that was preventing this fix. Please excuse us for the inconvenience. Note that we haven't tested to place HTML in the head sections of the views, it is only tested if you place some code in Title and properties section of pages.
I thought it is possible already for a while with PowerTools?
Although, I still don't sure hot to setup page title on pure MVC mode.
If I use ViewBag.Title in my view PureMvcPageResolver throws "null reference" exception and I get YSOD. Can someone from Sitefinity confirm what is the way to set page title in MVC mode only????
I checked the release notes for 6.1 and SP1 and don't see anything related to this. was this indeed released?
Can you please elaborate what is the issue? Maybe it is Monday and my head is "slow".
By modifying root template you can specify whatever code you want on head and other places. Reference your custom JS or CSS. Or you mean something that should be resolved on server side? Like <% Whatever.RenderMyCustomCode() %>???
what i'm referring to is pure MVC. if you create an MVC widget and attempt to have this widget render CSS or JS references in the master layout template as a Section, they do not work and nothing is rendered. I believe it works in Hybrid mode, but not pure mvc.
Ah-hah, I see now. Yeah that would be a great if Sitefinity will support that. I join to this request!
So far as a workaround I use combined CSS file that contains everything necessary in it.
As for JS files, you still can include them in widget's view but it will be in the page's body (where widget is rendered).
The Sitefinity power tools allow you to create a root template and put your scripts there. The basic idea is to implement the IRootTemplateResolver class in your custom Resolver class and return the path to a template file. If you register your custom class on the Application_Start event in the Global.asax file it will act as a layout to your MVC views. Here is an example:

I'm trying to use github.com/.../Root-Templates (for replacing pure MVC root template) and have an error (see log below) when trying to load page based on my Pure MVC template.
