We'd like to distribute the standalone report tool to our clients and provide data through a web service. We don't want to have to redistribute a dll everytime we make new data available. The standalone report tool should be able to query our webservice for what data is available and then allow the client user to create reports from it. i.e. obtain list of table names dynamically as well as their column names and data. A possible solution is to allow the tool to view and interact with classes in an external assembly that are dynamically generated with Reflection.Emit.
