You want to know if you should use fully qualified names when working with types in your code.
You’ll want to avoid using fully qualified type names. Make statements shorter by placing using statements at the top of source files.
There’s a nice convention to follow with using statements. List all .NET namespaces first and then ones imported from third-party libraries. In addition, always list nested namespaces after their enclosing one.
using System; using System.Timers; // Nested namespace. using OpenQA.Selenium; // 3rd-party namespace.
