I am trying to setup PiranahCMS into my MVC application. I am able to create database and access Admin (Manager section) where one can create pages etc as below:

What wrong I am doing here?
Please let me know in-case any other information is needed.

Answer 1

By looking at the error message I'm guessing you have used a version of Piranha CMS that is intended for ASP.NET MVC 5? Which version of Piranha CMS have you installed. Version 2.1.x is for MVC 4 and version 2.2.0 was upgraded to MVC5!
Cheers
UPDATE
I finally noticed something wrong in one of your comments. You say you installed the package PiranhaCMS, but this package is for ASP.NET WebPages. The correct package for an MVC solution is PiranhaCMSMvc.
Hope this solves your problems!
