    Media Picker Dynamic foreach loop not working? (Umbraco v7.6)

    I can't get even the most basic of examples running using the Media Picker "Dynamic" example supplied in umbraco.org's media picker documentation.

    I keep getting this error:

    System.Collections.Generic.List

    I can get the "Typed" version to work without any issues, but only if the media picker does NOT allow multiple items to be checked. After a long and exhausting search I still cannot find a solution.

    Here's a copy of the code I'm working with:

    @if (CurrentPage.HasValue("sliderPictures"))
{
    var caseStudyImagesList = CurrentPage.sliderPictures.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
    var caseStudyImagesCollection = Umbraco.Media(caseStudyImagesList);

    foreach (var sliderPictures in caseStudyImagesCollection)
    {
        <img src="@sliderPictures.Url"/>
    }
}

    Anyone else having this issue ...? Any help would be appreciated.

    UPDATE ... I managed to find a related thread with both the "cause" and the "solution" ... thanks to Josh Bula and Jamie Pollack this has been resolved ... see below:

    Here's my updated code block that WORKS (so you can see the applied edits):

    @if (Model.Content.HasValue("sliderPictures"))
{
    var caseStudyImagesCollection = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("sliderPictures");

    foreach (var sliderPictures in caseStudyImagesCollection)
        {      
            <img src="@sliderPictures.Url" style="width:300px;height:300px" />      
        }                                                               
}

    Here's a link to the related thread that I found both the answer AND an explanation as to why this is happening in Umbraco v7.6:

    https://our.umbraco.org/forum/templates-partial-views-and-macros/85128-media-picker-in-76-rc-input-string-was-not-in-a-correct-format

    The only thing they didn't do is include a sample code block with the solution applied (which is now listed above).

    I hope this helps!
