Hi - I wanted to dynamically set the main Layout View used based on some doctype hierarchy rules using the current content context. I thought the special aspnet ViewStart would be a good place for this logic to reside.

However, this didn't work:

var currentpage = umbraco.AssignedContentItem;

with the error: InvalidOperationException: Cannot return the IPublishedContent because the UmbracoHelper was not constructed with an IPublishedContent.

but this does:

var currentpage = _umbracoContextAccessor?.GetRequiredUmbracoContext()?.PublishedRequest?.PublishedContent;

The first approach feels "nicer" but anyone able to explain the technicallies of why that doesn't work but the context accessor way does?

thanks
