I recently downloaded the Windows Workflow Hands On Labs for WF beta 2 and found the samples to be less than perfect. For instance the state management example (Lab 04) doesn't even build because there are some workflow fields set to private instead of public. Remedy that and the application will run. Not that it'll help... it crashes almost immediately. Looking at the code I can see that it is not beta 1, but I assume that it is pre-beta 2. This is a big disappointment because I'd like people within my company to do the labs to get to know WF. I hope the WF team tests and debugs the current hands on labs and puts out a new download that works well with beta 2.
