A few days ago, I decided to start learning C#. So, I got a book and started reading and practicing with code. I was surprised when I saw that string in C# is considered a primitive type.

But I was more surprised when I saw that string, as well as all the other primitive types in C# have methods. I'm a Java developer and my understanding was that primitive data types don't have methods, only classes have. But in C#, the following is valid:

string name = "alex";
Console.WriteLine(name.ToUpper());

How is this possible? Are they really primitives? What am I missing here?
