For deployment purpose, you may want to merge your dotnet assemblies.
Microsoft provides ILMerge to do such thing !
Although this tool is very usefull, it's also pretty raw, so you may use a GUI wrapper such as ILMergeGui.
To finish this article, and because a good developper is a lazy developper, I warmly recommand to use NAnt in post-build generation event to automate the merge.
Happy merging !
