This will show you how to place partial templates into separate files, and how to put functions you need in many places in separate files as well. It focuses on:

1. @Html.Partial(...) to render another page (older versions of 2sxc used @RenderPage(...)) - see docs
2. Func<dynamic, dynamic> micro-helpers are ideal for small sub-templates - see docs

When Using other Razor or Code, you should also know:

1. DynamicModel is the object used in sub-pages to receive parameters from the caller - see docs
2. CreateInstance(...) to create objects from .cs files - see docs
