Hey Matt great job with Amplify!! I have decided to have a look at it and I have 2 questions. I have used the Article/Articles as a Template for a Blog section. They are identical in that one was used as a template for the other. On my new Blog/BlogPost model I am having issues getting the Sidenav to work. It complains that model has no property for Sidenav? ie.. Model.SideNav().HasValue() generates an exception. Obviously this has something to do with models, but I seem to have no issues with any other properties in the model. Any thoughts??

Matt, I did extend the Models in the _Amplify.cs file to accomodate my Blogpost Model EXACTLY the same way you had the extensions setup for Article but when I include the _Amplify.cs file to make these changes I get a whole host of other compile issues and if I don't include it then it doesn't see my changes. Am I missing something else perhaps?

Installed Package Source. Here is the changed version of _Amplify.cs in the Models folder.

You can see the public partial class Blogpost additions I made. This may be purely a models thing since I have to have my Blogpost.generated.cs Model file included in the project for that Model to be recognized. Im using ModelsMode=AppData in the web.config but I have also tried ModelsMode=LiveAppData. Having a bear of a time with Models in general. I am working with a Nuget pkg Install of the base Umbraco 8.10.1 site. Maybe thats the issue??

Here is the error:

Matt.....BRILLIANT!!! I guess the ModelBuilders was the whole issue I had all along. Nobody has taken the time to explain in detail how to get the models all synced up. Really appreciate you taking your time to explain. You Rock!!

Again, The help is GREATLY appreciated. Now if I can figure out how to wire the Members up to AD I will be nearly home free!! Thanks again....
