Coordinate Reference System Transformations. This is a .NET library implemented with F#, but also usable from C#. Most of the test code is actually written with C#. The third-part libraries used from the F# code may also have been implemented with C#.

Coordinate Reference System Transformations. This is a "JVM library" implemented with Kotlin, but usable from Java. Most of the test code is written with Java, and the third-part libraries used from Kotlin are also implemented with Java.
