Someone from MSR forwarded me the link to ILMerge. It lets you combine multiple assemblies into one without opening up the source code. Enjoy - josh
From the ILMerge Site
ILMerge is a utility that can be used to merge multiple .NET assemblies into a single assembly. It is freely available for use from the Tools & Utilities page at the Microsoft .NET Framework Developer Center. Its license does allow commercial usage! If you have any problems using it, please get in touch. (mbarnett _at_ microsoft _dot_ com)

ILMerge takes a set of input assemblies and merges them into one target assembly. The first assembly in the list of input assemblies is the primary assembly. When the primary assembly is an executable, then the target assembly is created as an executable with the same entry point as the primary assembly. Also, if the primary assembly has a strong name, and a .snk file is provided, then the target assembly is re-signed with the specified key so that it also has a strong name.
