What is the purpose of creating interfaces for all of our repositories, making private readonly fields for those interfaces in our controllers and then referencing the interface for our SQL queries? As opposed to just using the repository directly....

What exactly is this doing near the top of views? Is this basically tying the view to a specific method on the controller?

@{
ViewData["Title"] = "Create";
}

_ = (dog.ImageUrl == null) ? cmd.Parameters.AddWithValue("@imageurl", DBNull.Value) :
cmd.Parameters.AddWithValue("@imageurl", dog.ImageUrl);

just wondering what/why the underscore

In DogGo, when I added owners and walkers to the nav bar, they send me to localhost/home/owners rather than localhost/owners. Because of this, any links I add to the nav bar don't work.

rather than @walk.Duration they both achieve the same result

I've tried reading into the differences but I'm having a hard time understanding a hard time grasping the differences and why one should be used over another.

Having a cshtml view generated for us is great, but what about when we want custom layouts, divs, or detail views for a ViewModel page. Can we discuss the specific components needed for structuring an cshtml page for a ViewModel?

Is it a good practice to generally pull all data from the database pertaining to the model class, including object properties rather than just a foreign key?

Does more workable data = better? Even if you don't think you're going to use it initially.

i.e. joining a table(s) in the sql command string to build up new objects while building the parent object
