Our Focus

1. Text analysis: code points, normalizing behaviors between different "character sequence" types, tokenizing, etc.
2. I/O: Reading and writing types in both big-endian and little-endian byte order and providing specialized behaviors for interop with Java-centric file formats.
3. Collections: .NET's cupboard is a little bare when it comes to specialized collections, so we fill in some gaps.
4. Equality: Compare collections for structural equality with behaviors that are specific to each collection family, and provide .NET equality comparers for other types that differ in behavior.
5. Localization: Bridge the gap between .NET's culture-aware and Java's culture-neutral defaults.

Contributing

We love getting contributions! If you need something from the JDK that we don't have, this is the right place to submit it. Basically, the following are things that would be a good fit for this library:

1. Components in the JDK that have no direct counterpart in .NET, or the counterpart is lacking features
2. Features that make J2N easier to work with in .NET such as extension methods and adapters
3. Features that make .NET interoperate with Java better

Building and Testing

To build the project from source, see the Building and Testing documentation.
