    DynamicPublishedContentList does not contain a definition for 'Any'

    Why is this error.

    Clean install; mvc4 startup project in VS 2013.

    install umbraco (nuget)

    install MVC 5 (nuget)

    fails on:

    home.Children.Any() in a razor.

    managed to get it working with...

    var helper = home.Children as DynamicPublishedContentList; } @if (helper.Any())

    why is this and how can it be solved?

    kind regards,

    Hi Frans,

    Try to use strongly typed objects, DynamicPublishedContentList is dangerous and unpredictable.

    Thanks

    Have you tried? .Children.Count() > 0?

    Hi thanks for the reply.

    @alex since i don't know the type of the children. i need to have some thing generic. This is what the dynamic contains at the moment. Can you elaborate why is it unpredictable and/or dangerous.

    @John. Count() doesn't work either.... Since it's a dynamic... :-(

    All nodes are the same type, why you don't know what type ?

    DocType is different.

    So what kind of typed objects should i use.

    Is there a reason why the items are dynamic instead of a strongly typed list?

    Have you try like this one?

    var typedHome = (IPublishedContent) home;
    if (typedHome.Children.Any())
    {
        // do something
    }

    Thanks Jivan..

    Only problem is that intellisense still doesn't show the any extention. Do i need to add a using in order to get this working?

    Could you try this one? @inherits Umbraco.Web.Mvc.UmbracoTemplatePage

    I had this already... but that doesn't work.

    {

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage @using Umbraco.Core.Models @using Umbraco.Web.Models

    @{ IPublishedContent home = CurrentPage.Site();

    if (home.Children.Any())
{
    <h1>working</h1>
}

    }
