Thanks to everyone who came to my presentation today, I was humbled by the huge turnout! The presentation deck will be broadly shared to attendees which contains hyperlinks to all the tools showcased but in the meantime the links are below if you want to get started right away. I'll look to share the entire deck via the blog shortly if I'm allowed!
A new release of LoadGen has very recently been made available which I didn't mention today, this adds WCF support for injecting load amonst other things.
