Just came across this site: http://research.microsoft.com/research/downloads/ - there are some intesting things on there, that I am going to explore at a later date. A couple that jump out:
- ILMerge - ILMerge is a utility for merging multiple .NET assemblies into a single .NET assembly
- Treemap .NET- NET components that display hierarchical data as a set of nested boxes.
Cheers
