@sysrpl, @Maddus, I'm replying to this to support a request by Dennis to gather some support and give some objective feedback on people actually using XAF and not just expressing an opinion on it...
I have a healthy client base with thousands of windows and web client users who are delighted with their investment, in one very recent example a customer who was doing the training inadvertently let out a "that's absolutely £$%^& fantastic!"
Now for the puritans, if I delve into the support, commented coding, version control, examples, documentation et al, I'm sure I could cherry pick some examples where things have not been to my own subjective set of criteria, but on the whole I think you would be hard pressed to beat the time from design to deployment..
As for the technical issues that have been highlighted, right tool for the right job eh!, join the conversations and solve the issues, simple.. "Opportunity is missed by most people because it is dressed in overalls and looks like hard work." Thomas A. Edison
Btw, I would be more than happy to show you some real examples or arrange a conversation with you and the end users. Contact me for a Webex..
