Introducing support for Flexible Operators

In release 7.8 Xomega has tremendously improved support for operators that are used to build search forms and LINQ queries.

The framework comes loaded with standard operators for common data types, as well as dynamic operators for ranges of (relative) dates and numbers.

Entities generation revamped in Xomega 7.8

Starting from release 7.8, Xomega has completely upgraded the way Entity Framework classes are generated.

Entity Framework classes are generated now directly from the Xomega model.

Previously, the Entity Framework (EF) classes were generated using standard Model-First EF T4 templates from an Entity Data Model (EDM), which was in turn generated from the Xomega model. Now they are generated directly from the Xomega model using a new Xomega generator called EF Domain Objects. Generating EDM is no longer needed for the application, but that generator is still available in case you want to view your entity model on graphical diagrams.

This provides a lot of benefits as a result, such as the following....
