Error 500 in processing cshtml layout file

[simonespagna]

Hi guys,
When i activate a page in my web application I throw error 500 while debugging the following line :

 @Scripts.Render("~/bundles/jquery")
        @Scripts.Render("~/bundles/bootstrap")
        @RenderSection("scripts", false)

They are the last three line of layout file.
Any ideas?
Simone
