Q:

Sample WPF apps for line of business apps? 

I am learning WPF and wanted to look at source code to some good full fledged WPF apps which are used for business apps, data binding using data bound controls like grids and good use of WPF design and patterns. 
Not interested in WPF apps which show off WPF's graphics capabilities.  Yes I am into your typical boring business apps.  Also looking further than codeproject.com.  If you know something good at CodePlex, a pointer would be helpful. 
Any recommendations?  

A:

CodeProject.com is a very good resource for finding examples of .NET applications.   Some articles are at a "here's a control, here are some example usages", but there are the occasional full-fledged app write-ups too. 
Here are a couple of examples of some business-y WPF usage which may fill your needs:
