Question

I have a vendor model, I have a news item model. Can I make my vendor model optional inside of my news item model?

In other words…the news model is a class that will be turned into a view inside of my mvc project. This view will become a form that will create a news item. We want the option to associate a vendor with a particular news item (The news item is about the vendor, select the vendor from a drop down list), but we want this to be optional.

If I set Vendor as a navigation property of News item, doesn’t that mean that a vendor is required? How would I accomplish this?

Thanks for any tips.

Your relationship will have to be nullable and you can setup this relationship in the OnModelCreating event within your DbContext class. Here’s a similar questions.
