I needed to fake some data for a WP7 app yesterday and I was about to write a couple of classes when I thought why not check out what's available out there already...
Introducing Faker.Net on NuGet, with support for .Net 3.5 SP1, .Net 4.0, Silverlight & WP7.
Faker.Net support loads of different ways to fake data - addresses, names, phones numbers and more:
I can see where this could really come in handy... And probably so much better than using my pet's, family's, etc, names. ;)
