Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Basically, there is no difference between string and String in C#. "string" is just an alias of System. Both are compiled in the same manner. String stands for System.String and it is a .NET Framework type. "string" is an alias in the C# language for System.String. Both of them are compiled to System.String in IL (Intermediate Language), so there is no difference.
