I have scoured Google, but all the answers seem to be from older versions of Umbraco. I want to show 4 or 5 post excerpts on my homepage. I can get results for the "ArticulateRichText" type using the query builder, but when I try to access the properties in that collection like "Excerpt" and "PublishedDate", I get error messages about IPublishedContent and other things that I don't understand.

Here is my attempted code:

@{
            var blog = Umbraco.Content(Guid.Parse("208fb5bd-5f50-409f-bd7d-85357a1dc707")).ChildrenOfType("ArticulateRichText").Where(x => x.IsVisible()).Take(5);
            foreach(var post in blog) {
                <article>
                    @*<time>@post.PublishedDate.ToString("MM/dd/yy")</time>*@
                    <p><a href="@post.Url">@post.Name</a><br>
                    @*@post.Excerpt*@</p>
                </article>
            }
        }

The post URL and name work fine, but if I uncomment the date or excerpt lines, I get the following error:

System.Web.HttpCompileException (0x80004005): C:\home\site\wwwroot\Views\Home.cshtml(91): error CS1061: 'IPublishedContent' does not contain a definition for 'PublishedDate' and no accessible extension method 'PublishedDate' accepting a first argument of type 'IPublishedContent' could be found (are you missing a using directive or an assembly reference?)

If anyone can help me solve this I would greatly appreciate it.
