In 1995 when they roled out the "new paradigm" of OOP Booth and Speedy and the other evangelists were showing objects talking to each other and objects defined based on use case roles etc and no one ever showed a practical way to actually do those kind of object in VFP. Everything everyboyd wrote in VFP was RDMS code (at best - most of what I got called in to fix was bad dBase or FPD FPW code) with properties and methods (maybe) and in the more sophisticated frameworks business "objects" etc. that at least allowed for good n-tier design But the model was based on the RDMS tables.

The "entities" that were part of the original discussion just never materialized. I remember about 2000 somebody talking about ORM ( the missing piece ) and it made no sense to me at all.

Then when there was talk of EF and nHibernate etc I started to see what they were talking about, but it still seemed an immature technology or at least tool set. Then came 4.0.

For some reason once I "got" the terminology - especially "navigation" things really started to click. The ORM was built in ( Julia's videos on creating the EDM from Database and then the reverse really brought that around for me ), the LINQ suddenly seemed useful and then Ideablade's docs answered a lot o fmy questions about what I thought might cripple n-tier deployment. (the stuff they do with a disconnected entity cache really opens up some possibilities.)

I've been chugging along with Winforms and VB and Strataframe business objects that are very powerful and very well designed for Winforms and apps that work like my VFE apps worked. Good stuff. But it won't translate well to WPF and would require a *lot* of rethinking. MS seems to indicate EF is the direction they had in mind with WPF and I think with VS 2010 it's pretty obvious WPF is where .NET development is going. ( one .net wasn't scarey the transition to C# was remarkably easy - got tired of looking at LINQ examples and having to try to translate.)

WPF makes more sense to me than any UI implementation I've ever seen so I'll play. Between Blend and DevExpress WPF controls the weak link is just my own design skills ( and the temptation to put in waaay more sizzle than I need just because I *can* <g> The old "I've got a Mac with 50 fonts - and here's a ransom note" syndrome )

This stuff is fun again.

>>Long ago, Cetin suggested Ideablade's DevForce to me but only now as I am transitioning to C# and have fallen in love with WPF and the Entity Framework am I really seeing that DevForce 6.07 and its Entity support is the wave of my future.

>>And most impressive is the incredible level of documentation !

>>And apropos of that : DevExpress has been a constant source of delight - both in their amazing documentation, training videos, samples and support.

>>It is a joy to see people really doing it right.

>>I loved what I was doing in the VFP/VFE days, but VS 2010 and these two tools have made all that seem like the days of writing Applesoft.

>I've got the book but must admit I didn't find it an easy read. She sure knows her stuff and I learned a lot - but it was hard work. Then again maybe it's not possible to explain EF in terms I find easy to understand :-{.
