Memmingen small


In October 2023 we are organizing our second European conference, after a successful first event in 2022.

Since we are a small open source project, and we have limited financial resources, we have chosen to organize this as a relatively low budget event. We have also selected a location in the south of Germany, so developers from Switzerland, Austria, and North Italy are also able to come with a reasonable travel time.

We will present the current state of the X# development and show how to migrate your apps to XSharp. Furthermore, we will also discuss the internals of X# and how you can extend X#.
Finally, we will discuss our future plans, such as our support for next versions of .Net and will show some work in progress.

This summit is structured to encourage open and facilitated face-to-face discussion and idea sharing amongst all attendees. Refreshments will be provided all day, with scheduled lunch and snack breaks.


The event will take place at the following hotel:
Hotel Weisses Ross
Kalchstraße 16
87700 Memmingen


During the last months, we have received several questions from (beginning) X# users about the conversion from their apps to X#.

We have come to the conclusion that it may be worth to organize "Q&A sessions" now and then where we can go into more detail about these issues.

The first of the sessions is planned for Friday, April 28, at 16:00 CEST (GMT +2). The length of the session is scheduled for 1 hour.

We will use Zoom for the session.

The zoom link for the session is:

If you have a topic that you want discussed, then you can send that topic (or your code) to If you do, then we have some time to prepare.

Of course, we will also try to answer questions that come up during the session, but we can't guarantee that we will have the answer ready then.

If there are no questions at all, then we'll probably show some of the things we have been working on.


Jonathan Neil (Edwards Sound, Lighting & AV) has shared his experiences with the conversion of a very Inventory Tracking application, written first in Clipper and later in Visual Objects 2.7 to X#.

You can find his article here.

Important in this article is his experience that migrating his application to X# and recompiling it in X# has helped him to solve several ( 40+ ) serious errors in his VO code that the VO compiler had missed. Fixing these errors helped to make his VO application more stable (while working on the migration to X#).
