More details and a list of all editions of the DBB is available on the main page http://davidburela.wordpress.com/developer-blog-banter/

This weeks topic is was inspired by a recent blog post by Paul Stovell.
When starting a new software project, what is your default choices for your technology stack. What common libraries and toolkits do you find yourself reusing again and again.
You can answer the question either from the perspective of “your perfect personal project”, or what your standard choice is for what your day job requires.

Some suggestions to help you get started

• What UI technologies are you using, web? ASP.Net vanilla, ASP.Net MVC, WPF, Silverlight, Ruby, etc.
• What would you use to persist / retrieve data. nHibernate, Entity Framework, perhaps you’re using MongoDB as your store.
• What testing tools / frameworks do you use.
• Are there any other supporting frameworks you would use in your stack, like Log4Net.
