Hi,
The class designer.cs is the product of code generation which create the relevant entities and context that you will need in order to communicate with the database. You shouldn't change the generated code! All the entities and the context are created as partial classes so you can add your own behavior in another partial class.

I hope it will help you.

Well,
ORM in computer software is a programming technique for converting data between incompatible type systems in object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.

Simple details about it can be read here: WIKI ORM[^]

Object-relational mapping (ORM, O/RM, and O/R mapping) in computer software is a programming technique for converting data between incompatible type systems in object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.

Advantages of ORM as as follows:

1. Facilitates implementing the Domain Model pattern.
2. Huge reduction in code.
3. Changes to the object model are made in one place.
4. Rich query capability.
5. Navigation.
6. Data loads are completely configurable allowing you to load the data appropriate for each scenario.
7. Concurrency support.
8. Cache managment.
9. Transaction management and Isolation.
10. Key Management.

You can also try following line for newline in richtextbox.

richTextBox1.Text = "Some text " + Environment.NewLine + "Again some text.";
