Building a WPF Application: Part 0

In a rather indirect way, I was inspired by a commenter on one of Scott Hanselman's posts to begin a series that walks through building a WPF application from start to finish. We did this for four different applications in our book, but those where targeted to demonstrate particular facets of WPF whereas in these (yet unwritten) posts I'd like to focus more on "this is how I build my WPF apps". Not to say that my way is the *right way*, but so that we might learn together. In the spirit of the aforementioned post, I'm bound to make mistakes, so please (gently) correct me when you think you see one.

What to build?

You might not have noticed, but there's quite a bit of .NET chatter in twit-space. There are already lots of Twitter clients, and some are WPF, so that path has been rigorously trod. However, the technical difficulties surrounding Twitter has given rise to the popularity of another mash up web 2.0 thingy app called FriendFeed.  Everyone seems to agree that the web interface for FriendFeed is all stinky bad, and there's an API readily available, so I think a FriendFeed client is in order.

What to do?

I'm not going to set an agenda or outline a detailed plan. I'm just going to post as I have time to work on it. I started tonight, so I'm expecting to have a real Part 1 posted by midweek. I've already set up a project at CodePlex (though it won't be published for a few more days still.) I named it ChumChase. Isn't that great?

Part of my plan is to step you through my thinking and decision making process in sort of Nilssonian way. I've only just begun but here's what I can tell you so far.

  • I'm going to use a Model-View-Presenter pattern
  • Expect to see some DDD artifacts.
  • I'm going to use NUnit and RhinoMocks.
  • I'll probably use Windsor too (or maybe StructureMap though, anybody have a preference?)

I had intended to write a set of user stories  using the issue tracker of CodePlex. However, I got tired of retyping them every time the site errorred out, which was about 60% of the time. (Is that typical for the CodePlex issue tracker? This was my first usage.)  It also occurred to me that I am lazy and ought to have a life outside of coding, so sorry no user stories.

What to think?

I'm all about conversation. If this interests you, please let me know. I welcome (friendly) criticisms as well. The more I hear, the more motivated I'll be to do it.
