Visual Studio 2010 comes with a whole pile of project templates (C# WPF project, that sort of thing) and snippets. They get you started on new projects and save you a lot of time. But if you're a StyleCop user, they can frustrate you, because the code they generate for you can generate plenty of warnings.
The solution: new versions of these snippets and templates that are StyleCop-compliant. Plenty of XML comments, nothing left to default, generally nice code. Doug Holland has a blog post on this
with plenty of examples and links. Take a look!
