What to look at exemplary open-source projects on WPF?

Question

.NET

I have a fairly long and rich experience in development under WinForms. I’m finally trying to master the transition to WPF, I’m looking, reading, and everything seems to be theoretically clear (moreover, there is even some enthusiasm), but it doesn’t add up to a single picture of how to develop a conceived application from scratch and it doesn’t add up in the right way - there are so many ways you can achieve the same results and no clear "rails" for the development process are offered.
I want to try to take a high-quality ready-made application with well-built code and dance from it, making my own in its image and likeness.
Interested in a classic desktop application for Windows 7, no graphics, no frills. Working with files, a bit with web services (but you can already think of it yourself, the main thing is to build a framework and interaction between elements), toolbar, statusbar, grid, master-details view, CRUD, all that.
Advise what projects to pick.
Thanks in advance.

Answer 1

AvalonDock
Although it's not an application, but a component, I think it's worth taking a look at.
And if you do not need full-fledged applications, then you can look here: code.msdn.microsoft.com

Answer 2

I would suggest reading about Prism: msdn.microsoft.com/en-us/library/gg406140.aspx
Although this is not a ready-made application, you can learn a lot of useful patterns from the documentation that are used in WPF development.
