The Dynamic Language Runtime powers IronPython and IronRuby. It contains the following features:
- Hosting APIs - allows embedding of any DLR language as a scripting language inside of a host application
- Extensions to LINQ ExpressionTree - allows language compilers to generate higher level constructs instead of MSIL
- DynamicSite - call-site caching to speed up the performance of dynamic languages
- ActionBinder - utility code to facilitate .NET interop
- IDynamicObject - interface for dynamic objects
- Other compiler utility code
Mailing lists
You can currently ask questions on the IronPython (link) and IronRuby (link) mailing lists. There is currently no dedicated DLR mailing list. We are looking into it. Similarly, the sources for the DLR are bundled with the IronPython and IronRuby sources.
