                                    I am asking this without knowing much about MVC, but here it goes anyway.
                                    So the questions is:
                                    1. is it technically possible to have MVC integrated with XAF?
                                    2. if yes, does it make any sense to do it?
                                    3. Is DX planning... [ok this one is withdrawn]

                                  Hello Evgeniy,

                                  Yes, it should be possible. We have already allocated a separate team and are researching in this direction. We already have first results but, of course, a lot of work still needs to be done.
                                  I have just spoken with the lead of this team, and he said that during the research they came to the conclusion that there are some performance issues caused by the current XAF design and that they should be solved first before moving to MVC.
                                  I have converted your question to a suggestion, so that other customers can track it.

                                  Thanks,
                                  Dennis

                                  Dennis, excellent news!

                                  (Especially about peformance issues)

                                  Looking forward to screen shots on the blog :)

                                  Is there anything new to MVC UI?

                                  We really need modern, responsive web UI.

                                  Xafari published CTP version of XAF ASP.NET MVC.
                                  Now implemented about 70% XAF abilities.
                                  See MVC demos and compare with original demos on https://demos.galaktikasoft.com/

                                Hello,

                                I wanted to close this ticket for now as we do not have immediate plans for the ASP.NET MVC-based Web UI for XAF. Instead, we are currently working towards making the existing ASP.NET WebForms UI more modern and responsive with preserving almost all the functionality users of the former XAF Web UI were accustomed to (learn more from this blog). So, I wanted to invite you to test the improved Web UI as per instructions given in the How do I enable the new page templates and theme optimized for touch devices (CTP) for existing XAF Web 15.1 applications? article. Your feedback in this regard is very important and will be considered by our team with the highest priority. Thank you in advance!

                                  Hi Dennis, it need not be necessarily MVC. But it must necessarily use speaking URLs and work in several tabs possible (see https://www.devexpress.com/Support/Center/Question/Details/Q577531). This is the new layout is not yet that. I hope this will be changed.

                                • Dennis (DevExpress Support) 07.22.2015

                                  Thanks for your feedback, Mario. Yes, I look at your other ticket just a few hours ago and our team understands your requirements and will take them into account.

                                • Mario Funke 07.22.2015

                                  Good News :-)
                                  It should also open and close the layout groups possible (see https://www.devexpress.com/Support/Center/Question/Details/T242411)

                                • Dennis (DevExpress Support) 07.22.2015
                                  Yes, we are already aware of this suggestion as well. Thanks.

                                  I recently started to learn MVC and it is great for complex web development.
                                  Not that I am not content with WebForms, but XAF would fit perfectly in ASP.NET MVC, so hopefully XAF MVC will get back on your roadmap table sometime in future.

                                  Hi
                                  I want to share the results of the comparison 2 versions of the same application.
                                  The first version is implemented on XAF WebForms, the second - on Xafari ASP.NET MVC.

                                  We tested the same use cases in applications that are running on the same server (25GB, 8 cores).
                                  WebForms version stopped after 30 minutes for 10 concurrent users.
                                  MVC version worked for more than 7 hours (until the end of the test) for 40 concurrent users.

                                  ASP.NET MVC has allowed to implement a more stable XAF application that also successfully scaled to the number of concurrent users.

                                  Maybe there are new plans to implement XAF ASP.NET MVC.

                                  Are you tried to use the XAF new web scheme with your MVC engine?

                                • Mario Blatarić 10.06.2015

                                  I also noticed problems with scaling XAF web apps.
                                  I have intranet web app used by 600 users and it tends to get quite sluggish.
                                  Would love to see MVC version of XAF some day.

                                  It is well known that the footprint of the current xaf web is too heavy.

                                • Sergey Zaitsev (Xafari Team) 10.06.2015

                                  We use Xafari MVC product to test application. (https://demos.galaktikasoft.com/)
                                  New XAF web schema is not yet ready.
                                  We plan to complete works int this year.

                                • Stanislaw Tristan 10.06.2015

                                  Sergey, I wish you a good luck with this implementation, because I think this is the best conjunction for XAF: your MVC engine + new web theme.

                                  Would you please submit a separate ticket and attach a debuggable version of the application you tested, because these results look strange, unless there is a problem in the custom application code or environment settings? Thanks.

                                  We think that for the majority of XAF customers it does not really matter what is "under the hood" (ASP.NET WebForms, MVC or even HTML5) as long as the framework development approaches make them productive and the final application does what it was designed for well. Previously, we had questions on the general look and feel of the Web UI and as I wrote above the new Web UI should address this. We also have a few requests for better scaling of XAF web sites and our team is taking them into account (current considerations on this are given in this thread). Thanks.
