So, effectively, if you have a calculated column with UniqueName=" RejectedInvoices " , it will sort your data objects if you expose a public property named " RejectedInvoicesResult ". Entity Framework 6 with a Database Generated field is failing on insert. From what I've read once you mark a column as DatabaseGenerated, EF won't try to insert/update anything into that field, which is especially important in my case because the fields on the database are SQL Server computed columns and not just default values, which is what I've seen in a lot of similar questions on Stack Data Annotations - Column Attribute in EF 6 & EF Core.

I want to do CRUD on this table through Entity Framework.
