This was a great event, the audience shared lot of useful information along with the speaker too.

"Ninja" might be an exaggeration, but there were plenty of good tips for people new to C#. Some topics deserve their own presentation, such as LINQ.

I had a good time; the presenter was really good, the content was interesting and I enjoyed the discussions that broke between the present and the speaker.

I liked the talk. But it was more Karate purple belt than Ninja.

Good, although not as much subtle tricks as good things to be aware of.

Can't wait for jedi training.

Ben's talk was very entertaining and he did a great job interacting with the audience and getting a discussion going. He hinted at testing at the beginning, but I would have liked to seen him present writing more tests as the 11th easy step.

I felt that the steps presented and the concepts behind them were outstanding. I had gained knowledge from the material presented. To me the title was a little misleading, as I thought this was approach to write an entire application instead of snippet of code. Some snippets were very clear and simple. Others were not.

Surely Ben combines presentation skills of a pro piano performer with insights of an experienced C# developer. Like most good Microsoft seminars Ben's presentation followed this strategy of actively involving audience into discussion of the presented topics. And this works great! The only humble suggestion: this kind of meeting might benefit (especially in cases of such high attendance) from using a microphone so that the questions of the attenders could be heard by everyone, provided that those asking come in front to grab the mike or rather a lecturer's help/TA could rush to deliver a mike to anybody asking a question (this is the way it is usually organized at research conferences). Actually Ben's restating the questions also works! I highly recommend Ben Day's DevBoston Meetup!
