New DynamicMethod Class in the CLR
Joel Pobar has recently posted some great introductory material regarding the new DynamicMethod class being added to the CLR:

Late-Bound Invocation Notes
DynamicMethod will allow runtime code generation to occur at a finer level of granularity, with better performance, and presumably without the resource hogging issues that exist with dynamic assemblies today. This is going to be a great addition to the CLR and we certainly would have made extensive use of this functionality had it been available to us during the implementation of Codify.
Beta documentation for DynamicMethod is available on MSDN:
