In addition, the hosting API allows interoperability with statically typed CLI languages like C# and Visual Basic .NET.
[6] The open source DLR project hosted on GitHub has a few additional features for language implementers.
In 2007, Microsoft initially planned to use the DLR for the upcoming Visual Basic 2010 (VB 10.0) and Managed JScript (ECMAScript 3.0) as well as Python and Ruby.
[13] Fredrik Holmström later independently contributed a JavaScript implementation for the DLR which he dubbed "IronJS" in the naming tradition of IronPython and IronRuby.
Like C#, Visual Basic can access objects from dynamic languages built on the DLR such as IronPython and IronRuby.
[19] This architecture is backed by the idea that the number of elementary language constructs that would have to be implemented on the generic stack should be inherently limited.
