    Umbraco Installation Error

    I am unable to install application i am getting following error while installing from VS 2015 - I don't want to use WebMatrix.enter image description here

    Error CS1061 'IPublishedContent' does not contain a definition for 'Ancestors' and no extension method 'Ancestors' accepting a first argument of type 'IPublishedContent' could be found (are you missing a using directive or an assembly reference?) UmbracoCms.7.6.4

    Please fix the setup asap.

    The methods for querying (like Ancestors()) are extension methods and located in the Umbraco.Core.Models assembly. Therefore you have to reference it.

    Just write @using Umbraco.Core.Models above @inherits ... in the first line and you have them available in your code.
