 The preceding tutorials worked with text and numbers. Strings and Numbers are *simple types*: They each store one single value. As your programs grow larger, you need to work with more sophisticated data structures. C# provides different kinds of types you can define when you need data structures with more fields, properties, or behavior. Let's start to explore those types.

 ## Create record types
 
 Tuples are great for those times when you want multiple values in the same structure. They're lightweight, and can be declared as they're used. As your program goes, you might find that you use the same tuple type throughout your code. If your app does work in the 2D graph space, the tuples that represent points might be common. Once you find that, you can declare a `record` type that stores those values and provides more capabilities. The following code sample uses a `Main` method to represent the entry point for the program. That way, you can declare a `record` type preceding the entry point in the code. Press the "Run" button on the following code to replace your existing sample with the following code.

 The following code declares and uses a `record` type to represent a `Point`, and then uses that `Point` structure in the `Main` method:
 
 :::code language="csharp" interactive="try-dotnet-class" source="./snippets/TuplesAndTypes/PointEvolution.cs" id="PointVersion2":::
 
-The `record` declaration is a single line of code for the `Point` type that stores the values `X` and `Y` in readonly properties. You use the name `Point` wherever you use that type. Properly named types, like `Point`, provide information about how the type is used. The `Main` method shows how to use a `with` expression to create a new point that's a modified copy of the existing point. The line `pt2 = pt with { Y = 10 }` says "`pt2` has the same values and `pt` except that `Y` is assigned to 10." You can add any number of properties to change in a single `with` expression.

 The preceding `record` declaration is a single line of code that ends in `;`, like all C# statements. You can add behavior to a `record` type by declaring *members*. A record member can be a function, or more data elements. The members of a type are in the type declaration, between `{` and  `}` characters.

-When you declare a `record` type, you declare that your type should use a default set of behavior for equality comparisons, assignment, and copying instances of that type. Records are the best choice when storing related data is the primary responsibility of your type. As you add more behaviors, consider using `struct` or `class` types, without the `record` modifier.

 You use `struct` types for value types when more sophisticated behavior is needed, but the primary responsibility is storing values. You use `class` types to use object oriented idioms like encapsulation, inheritance, and polymorphism.
