In March 2019 we are organizing our first US event, where we would like to meet our customers and potential customers from the United States, Mexico and other countries around the world.

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 chosen a location in the south of the US, so developers from Mexico and other Middle American countries are also able to come with a reasonable travel time.

The main audience for this event is existing Visual Objects and Vulcan.NET developers. However developers working with other XBase languages, such as XBase++ and Harbour, are also invited, there will be enough interesting information for you as well.

We will present the current state of the X# development and show how to migrate your apps from VO to .Net. We will also have time to explain some of the internals of the X# compiler and runtime and how you can use the new features in the product (generics, lambda expression, linq, scripting, multi threading etc) in your apps. We will also show you the support that we have for other dialects (such as XBase++ and Harbour).

Our partner QLAdmin from Austin has helped us to set up an event that will be both informative but also attractive. You have the chance to meet colleagues that create applications with the same tools, as well as enjoy presentations where we will demonstrate our new open source solution to help you move your applications forward towards  .Net.
There will be some other interesting technical sessions as well.

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. You are also invited to join in the group activities to continue your informal networking and make new friends in the X# world.
