The SQL 2005 Assembly Browser is a little add-in for Lutz Roeder's .NET Reflector that can be used to browse .NET assemblies stored in a SQL Server 2005 (Yukon) database.

You can connect your local Reflector installation to a remote SQL Server instance, list the databases and its assemblies and download them directly into .NET Reflector.
