User-friendly XAF-Web-Version (eg XAF-MVC-Version)

This is an approach in the right direction. But there is still a solution to be found if urls are always written in lower case.
BrowserHistoryMode = BrowserHistoryMode.FriendlyUrl
Routes.LowercaseUrls = True

Thank you for this case, Mario! You can find a way to implement this functionality in my answer in the Web - How to support case-insensitive URLs ticket.

I totally agree. We need a responsible and more user friendly XAF Web application and easy integration with DevExtream mobile.
But first - XAF Web application.  It is totally outdated.

suprising , we are in 2016 and i can say the new web ui introduced in nothing to write home about. it have been about 10 year i was introduced to devexpress xaf, and xaf web is just static, nothing new significant. I thought their web ui should have been a matured ui by now, but it just look like a child's play. there is nothing professional of that ui. For me i think they are just taking the developer community for granted. its long over due for xaf new web ui to be professionally designed with themes and much responsive. As someone said the web is changing rapidly and xaf web is about 1000 years behind, with just some scanty update of no relevance. for this reason i have stopped evaluating the product, but i come back some time to check if there has been something new, but its the same old story each and every time i visit.

@Peter: Based on your Support Center and various forum threads history for your last 6-7 trial periods starting with 2008, I found out that you really tried to thoroughly evaluate the product to see whether it meets your needs. We greatly appreciate your interest in our development tools in all these years and taking the time to share your opinion here.

Well, it is sad that you have not found various DevExpress components and XAF in particular helpful for your business as thousands of our customers do. Even though I think that nothing I can write here will change your personal opinion, I wanted to use this opportunity to learn more on your project's specific requirements (a public or internal web portal, planned number of users, typical use-case scenarios, screenshots, videos or links to ready apps, etc.) and get to know what tools you are currently using. It is quite possible that XAF is simply not the right product for your projects (e.g., public e-commerce sites), because we have initially chosen a concrete market niche and user base, for which we have been trying to deliver our best since 2006. While it would be great to have one tool to handle all requirements, in the real world it is difficult or even impossible to meet each user expectations in all scenarios at the high level… It's like creating a fast race car that would also be a good SUV and comfortable sedan at the same time - this is a nice wish, but it is not ever possible. I hope I explained my point well.

I also wanted to re-confirm whether you have really tested the XAF New Web UI, because it is more modern-looking and responsive as compared to the old good Classic UI you might have been testing in the past. Among other features, the new version provides features like content adaptivity (menu commands, grid columns, popup window position and size, etc.) depending on the form factor. Many XAFers welcomed these improvements through the last year or two not only for this, but also for greater performance, especially in the latest v16.1. For instance, here is a recent comment we received from an old XAF customer from Russia (check this Google Translate link for a translation) that describes how his end-users loved these changes as compared to the old version:

Of course, this is not the only positive comment we received from many different customers and  there are still things we would like to improve there, as in any software in the world. I hope this example shows how different business requirements and expectations can be for different people. Feel free to email us at management@devexpress.com or me personally at dennis@devexpress.com to provide additional information or if you wish to discuss this further. We will be happy to hear from you. Thanks.
