Dynamic languages are traditionally associated with an interactive environment, giving you a run-evaluate-print loop (REPL), and allowing for an explorative trial-and-error approach to programming. The Dynamic Language Runtime (DLR) is a dynamic language support system that sits on top of the CLR and provides language services required by most dynamic language implementations.

In the February issue of MSDN Magazine, Jimmy Schementi brings you up to speed on the DLR and demonstrates how you can use DLRConsole to interactively experiment with Silverlight using JavaScript and IronPython.

How do you integrate your managed and unmanaged projects? There are many factors that affect the way the CLR marshals data between the unmanaged and managed worlds.

Back in the January issue of MSDN Magazine, Yi Zhang and Xiaoying Guo explain some basic but often overlooked concepts that will simplify your everyday attempts to marshal between managed and unmanaged code, including the use of InAttribute and OutAttribute, return values, StringBuilder, memory ownership, and P/Invoke.
