High Performance AJAX-based Rendering
This release of XAF significantly improves the performance of applications targeting ASP.NET.
Domain Components
With a focus on productivity and to accelerate time to market, XAF Domain Components provide an elegant and highly intuitive way in which to create reusable modules that are abstracted away from a particular persistence layer. DXv2 marks the official release of this technology.
Functional Testing
XAF ships with new and extended functional test script commands – from Compare and Delete Files to CompareScreenshots – all designed to reduce app defects and improve product quality.

Enhancements to the XAF Localization engine further simplify the way in which you translate app resources.

DXv2 ships with significant enhancements to XAF’s Export functionality across all List Editors (for both ASP.NET and WinForms apps). Your end-users can now instantly export datain all XAF Lists (for both ASP.NET and WinForms apps) to a myriad of target formats, including PDF, RTF, HTML, XLS, PNG, BMP, etc.
Middle Tier Service
As the first step towards delivering N-tier architecture support, apps built using XAF can now obtain data from an Application Server.
Middle Tier Security
To better secure business data, XAF’s new Security Model ensures that client applications never retrieve sensitive data by redirecting permission requests to the security service running on the app server.
