As we make our plans for 2019 we would love to get your feedback, help us determine the features you would like to see for the DevExpress eXpress Persistent Objects (XPO) ORM library. ...

Thanks to great user feedback, we had a successful release with several major new features. In this post, I will highlight a number of smaller, but useful additions to our ORM and its associated learning materials....

Based on user feedback, we’ve updated our XPO v18.2.3 benchmarks against Entity Framework 6.2 and EF Core 2.1.4. Each benchmark now also compares ORMs with direct SQL queries to show ORM overhead. We also contributed to the Dapper performance benchmarks, so you can compare XPO with other micro and macro ORMs....

Reports are almost always bound to data – the more flexible our Reporting solution is when it comes to supported data sources, the more use cases we can cover. For v18.2 we added two new data source types that you can choose in the Data Source Wizard of the Report Designer....

With v18.2, XPO's Session and other key classes ship with a set of async APIs, including FindObjectAsync, GetObjectByKeyAsync, CommitChangesAsync (which return System.Threading.Tasks.Task object). These Task-based APIs are important for both server and client programming (useful for long and DB-intensive operations like commits, queries, delete operations, etc.) as they improve server scalability and deliver a more resilient user experience, especially on mobile devices....

As part of our ongoing commitment to support the needs of our XPO customers, the upcoming v18.2 release will ship with several major features. Many of them are inspired directly by customer feedback!...

Many times, customers have asked us how we use XPO – or if we even do it at all. We decided to sit down with developers working on and with XPO and conduct an interview, with the goal of answering the most common questions. The result makes for an interesting read since it addresses many historical, strategical and technical aspects. Enjoy! ...

With v18.2, XPO includes one additional community-driven feature - FetchOnlyAttribute. Applied to a class property or field, this attribute indicates that you can only read values from a database. XPO will not include these values in INSERT and UPDATE SQL statements....

We have received many comments and questions on our previous blog post. Thank you all for that! In this post, I will describe our updated benchmark based on your feedback:...
