We have many accolades from them.<br /><br />To my knowledge, only one customer has ever left DevForce for RIA. The reason, as best I could determine it, was the arrival of a new set of developers who favored following a Microsoft standard over all other criteria. I don't know how that panned out for them; I hope it went well. And I hope they have a plan for the coming years now that MS seems to have changed course (again).<br /><br />I recommend you contact IdeaBlade directly and talk to someone there about your project and your previous experience. They might be able to point you to something more tangible.<br /><br />All the bestWard Bellhttps://www.blogger.com/profile/10977457957771020146noreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-44842329816818404312011-11-21T08:47:33.132-08:002011-11-21T08:47:33.132-08:00Very late for a comment to this post, but I am goi...Very late for a comment to this post, but I am going round in circles on this one. DevForce seems to be claiming a major productivity improvement - and I can confirm that it is very fast to go from nothing to a first working app for a new developer. Is there, however, any metrics or other evidence availavble to demonstrate that a skilled DevForce developer will be significantly more productive than developer using a set of Microsoft-only technologies and appropriate other tools?<br /><br />I am looking for something that I could use as the basis for a business case for purchase. If I could realistically say that using DevForce the average productivity, once the learning curve is eliminated, might be even 10% higher then I would have a strong case.David Howardhttps://www.blogger.com/profile/08193110756663310741noreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-32322306701059491682011-01-31T21:47:22.620-08:002011-01-31T21:47:22.620-08:00@Shawnolius - A point of RIA/DF comparison is the ...@Shawnolius - A point of RIA/DF comparison is the Book Club by John Papa and the BookShelfDF by us.<br /><br />It gives you a feel: no DomainService, testability, etc.<br /><br />What you can't see in that example are all the things we do that you can't do in RIA ... because, perforce, they aren't in BookClub which is the baseline.<br /><br />You also can't see what happens as you evolve your model. You can't see how much easier DF is to maintain. <br /><br />I intend to demo that by pretending to change the model and following the steps. Try that yourself if you can't wait.<br /><br />Harder to demonstrate is the consequences of our much greater agility. RIA has YET to release any changes since v.1. They have an SP1 waiting. But it won't go out until who-knows-when. They seem to be pinned to big and slow MS release cycles.<br /><br />We release every 7 weeks. We respond to bugs and feature requests. You can ask us what is happening and we tell you. Try to find out what the RIA team is working on. Good luck.<br /><br />I don't have anything to compare to CSLA. Frankly, we haven't run into CSLA competitively ... as we have run into RIA.Ward Bellhttps://www.blogger.com/profile/10977457957771020146noreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-68141373722030888362011-01-31T19:47:03.587-08:002011-01-31T19:47:03.587-08:00mmm, this leaves one in a situation where you real...mmm, this leaves one in a situation where you really have to take a sample of functionality and build it using all three frameworks in order to answer the questions you say one should be asking.<br />I guess my question is, has anyone done this?

We've been in business since 2001 and 2010 was our best year. Hundreds of new customers this year for sure. <br /><br />We have several very large customers, among them a F100 institution with a customer-facing app that serves 5000+ small business customers (goal: 20,000+ by 2012).<br /><br />We're excited about 2011 especially now that SL is more widely appreciated as a business application platform.<br /><br />250 tables is modest size for our customers (some of whom have 1000+)as is 250 concurrent users.

My biggest problem is: will DevForce be able to deliver for my big app? CSLA.Net is great, but it's kinda slow. RIA Services is not 'compleet' enough. Alternatives? There is LightSpeed, but no idea how well this performs either. XPO from DevXpress is not mature enough for SL.<br /><br />Also, how many customers does IdeaBlade have on their latest version? This could proof the continouity of the company.<br /><br />My app has a database of over 250 tables and should be able to handle more than 250 concurrent users.

I'm not sure the probabilities are as clear as you suggest. CSLA has been around 12 years? IdeaBlade for 10. And, while Microsoft rarely discontinues support for a product ("Kin" anyone?), it does put them on ice. LINQ to SQL comes to mind.<br /><br />Infrastructure buy-versus-build is a balancing act. You can - and should - insulate yourself from uncertainty with loose-coupling and isolation techniques.<br /><br />Does the selected technology make that easy or hard? We've worked hard to make isolatation easier. I always recommend the Repository pattern, for example, as a means to increase application testability AND insulate the UI from the persistence machinery.<br /><br />I think you'll also find that we keep alignment with Microsoft APIs at the points where you encounter those APIs frequently. This is somewhat self-serving ... it makes it easier to convert from RIA Services to DevForce; but it also facilitates a fallback to RIA if things don't work out.Ward Bellhttps://www.blogger.com/profile/10977457957771020146noreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-45530208837026493332010-11-09T19:20:18.511-08:002010-11-09T19:20:18.511-08:00There is also one important point you forgot to me...There is also one important point you forgot to mention, and that is 'who is behind the technology'.

The question is do you want to lose productivity going against the grain of a tool because it's free or do you want to cough up a few dollars to get a tool that is better aligned to the other dimensions.<br /><br />Like Ward mentioned, if you value <b>your time</b> at $0 the choice is a no-brainer. Personally, my time is priceless and if something helps me spend less of it (and I have the budget) guess what I'm going to do?Browniehttps://www.blogger.com/profile/13126107055465643903noreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-89487003534044188632010-05-06T16:46:04.454-07:002010-05-06T16:46:04.454-07:00Thanks for the endorsement.

Plenty of heartburn running your own business but I like it and I like our IdeaBlade crew.<br /><br />Major: I am not IdeaBlade. I am not the author of DevForce nor its chief architect.

You reminded of two things.
Fi...Thanks, Anonymous. You reminded of two things.<br /><br />First, DevForce pricing has changed substantially since you last saw it. You may want to look again. <br /><br />I'm not supposed to be talking about pricing in this space but what the heck.<br /><br />There is a free, no-time-limit version, constrained to a model maximum of 10 entities which is great for exploration but rarely sufficient for production apps.<br /><br />Most DevForce 2009/2010 customers are paying $1000 per developer ... period. No runtime fees. No server fees. <br /><br />Second, of course license fees are part of anyone's calculation.<br /><br />I am saying ... predicting if you prefer ... that a few thousand dollars of license fees are peanuts compared to the total amount your company will invest in and derive from the timely arrival of your high quality, maintainable, "growable" application.<br /><br />Some organizations will determine that RIA Services or CSLA is the better choice for them. When their reasoning is sound, the license fees will have played a negligible part in their calculations.<br /><br />When you do your comparative analysis, if DevForce doesn't outdistance CSLA and RIA Services by far more than its license cost, please do not choose DevForce. It's that simple.<br /><br />--<br /><br />Now, can we please talk about the substance of this post?<br /><br />To that end, I will exercise my editorial prerogative to ensure there is no more commentary on license fees in this post.

Unfortunately for my company, we couldn't justify the cost of your product. I enjoyed working with it and your team, you guys are great.<br /><br />Obviously, justification for cost and production usage play heavily into decisions, as short-sighted as they may be. The months spent re-inventing technology already present in DevForce is a dumb proposition, but companies do it all the time.<br /><br />If your licensing model was a bit more relaxed, we would have stayed with you.<br /><br />Good luck man!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-37467881055416802062010-05-01T02:35:34.179-07:002010-05-01T02:35:34.179-07:00Sorry to offend, Fallon. Not my intention.
Noneth...Sorry to offend, Fallon. Not my intention.<br /><br />Nonetheless, I stand by my statement. Condescending and arrogant as I may be ... I am unequivocally right on this point.<br /><br />If you want gooey platitudes and a nice pat on the head for gifting the world with your free software look elsewhere.<br /><br />Hey, I enjoy free software as much as the next person. But I said at the top that these products target business applications built by and for business.<br /><br />Stake holders make economic calculations regarding opportunity, time to market/production, and all development costs including the cost of paying developers for their time. Incidentally, even when working on free software, do you value your time at $0?<br /><br />My point is that the costs and risks involved dwarf the licensing fees.<br /><br />I neither said nor implied that my product was a priori better than the others. I said that the three products are different.<br /><br />So different, in fact, that when you compare them in the manner I've suggested ... according to your specific development preferences and business requirements ... you will choose one over the others for reasons far more compelling than the cost of a license.<br /><br />We're not talking about competing brands of soap.<br /><br />Anyone incapable of grasping these points is ill-suited to making a business decision of such magnitude.<br /><br />That's just a hard cold fact. Read it and weep.Ward Bellhttps://www.blogger.com/profile/10977457957771020146noreply@blogger.comtag:blogger.com,1999:blog-393540894130950585.post-32241068238602318952010-05-01T00:50:45.505-07:002010-05-01T00:50:45.505-07:00You said,
"I have conspicuously omitted one ...You said,<br /><br /><i>"I have conspicuously omitted one factor: license costs. CSLA and RIA Services have no license costs. DevForce does. Why doesn’t that matter?<br /><br />It doesn’t matter because you’re building a custom application that you’ll be living with for years. A few thousand dollars of licensing fees are irrelevant … they are rounding error … compared to the application investment you’re about to make and the risks you are about to assume. <br /><br />If this is not blindingly obvious to you, you shouldn’t be making this decision. You simply don’t have the requisite business acumen to make the right choice."</i><br /><br />WOW!!! That's quite a statement! It's also condecending, arrogant, and ultimately wrong.<br /><br />What's blindingly obvious is that cost matters in some situations, like when the app you're building will be FREE! A lot of which are very complex apps, with the option for the vast majority of it being open source.<br /><br />Secondly, the relationship between having to live with an application for years, and the cost of any component are two orthogonal concepts. The blindingly clear implication is that the two products you are comparing against are inferior, so paying for yours is the intelligent choice.<br /><br />Even if that is true, you have made a really crude attempt to state it, and it really turns the reader off(at least it did for me).<br /><br />I understand and accept that you're biased, but you bias is very offensive.Fallon Masseynoreply@blogger.com
