SeedPacket adds a .seed() method onto IEnumerable so that you create a list of elements as easily as: var mylist = new List<Item>().Seed().
The rules engine keys off the datatype or interface, and name of an item's properties so that the data is appropriate to the type. That is to say, "out-of-the-box" - email properties will be filled with valid emails, phone numbers filled with phone numbers, and names are names etc. If you need to modify the default generated data the rules are simple to create and modify, and come with a many examples, including a data generator that pulls from an xml or json file or string. The randomly generated data can be set to always be repeatable or to be random on each request.
Go to http://www.seedpacket.net for more details.
See the version list below for details.
There are numerous improvements including :
*Xml or Json Support from either file or string using new DualGenerator
*Code reorganization to make customization easier
*SimpleSeed (an alternate approach without the Rules engine)
Unfortunately, these changes will require code refactoring for in-place upgrades.
