Selenium C# Java - What Is The Difference Between WebDriver & IWebDriver?

Question

I am currently learning Selenium in both Java and C# by using Selenium IDE to export recorded browser interactions. I notice in the Java code we use WebDriver driver; and in C# code we use IWebDriver driver; What is the difference?

Answer 1

C# convention is that interfaces are prefixed with an I, e.g. IEnumerable, IDisposable.

Java has no such convention.
