Abstract
I think it’s safe to say by this point that you are pretty comfortable with adding, retrieving, updating, and deleting records from a database using Entity Framework Core 2.0. Now it’s time to do something that’s a bit more exciting and slightly more difficult. We’ll start off by selecting only the columns we want in our query, as we generally don’t need every value in a table. In the example here, this might not seem like a big deal, but if you are working with a table that has 15+ columns and millions of rows, you can start to see why only getting the columns and rows that you need is important.
