X# Summit Memmingen 2020


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


We plan to have 2 days with 10 time slots and 2 parallel sessions. Sessions will not be repeated. The detailed list of sessions will be published later.
Some sessions, especially the sessions that discuss migrating applications, may span 2 or more time slots, so we can go into details.
One session room will focus on “generic” topics, and the other session room will focus on dialect specific topics, such as migrating FoxPro apps, migrating VO apps etc.

(Call for) Speakers

On behalf of the X# development team, there will be 2 or 3 members giving sessions.
We are also looking for other speakers. If you are interested in speaking, please send your session proposals to before June 1, 2023. 
We expect you to prepare a white paper or presentation about your subject with practical examples. Sessions should be code centric.
If you do not want to speak, but have a suggestion for a topic, please let us know at the same email address.

Like last year, we also plan to do a session in which customers can demonstrate applications that were migrated to X# showing apps “before” and “after” the migration with a short description of how the conversion went. If you are willing to demonstrate your app, please contact us.
Speakers will get free admittance to the event.
