Welcome

 
X# is an open source development language for .NET, based on the xBase language. It comes in different flavours, such as Core, Visual Objects, Vulcan.NET, xBase++, Harbour, Foxpro and more. X# has been built on top of Roslyn, the open source architecture behind the current Microsoft C# and Microsoft Visual Basic compilers.

If you want to support the development of X# or if you want frequent (monthly) updates, you can subscribe to the Friends Of XSharp (FOX) program.

Best Wishes!

On behalf of the whole devteam I would like to wish all our friends, customers and other people following our project all the best for 2017!

And I would also like to use the opportunity to share some news with you:

Last week we had our 2nd 'DevTeam Summit' in Athens. It was a little bit different this year compared with last year. First Fabrice could not attend because of health issues for a relative. And secondly it was cold, very cold. We had snow in Athens !

We worked a lot this week but also had some time for touristic attractions, as you can see in the image here.

One of the things we acomplished is that we finished the work on the Vulcan compatibility in the compiler. We were able to successfully compiler the complete Vulcan SDK including all kind of dirty tricks that are used in this SDK without code changes.

To be honest: we had to make a couple of changes, because our compiler found a few problems in the Vulcan SDK. If you ever wondered why drag and drop in the GUI classes is not working properly in Vulcan, then we have found the reason: there is code missing because of a typo in a define in the source code.

We also discussed our future plans for X# and you can expect updates on this website in the next couple of weeks.

As you can expect we will now pickup the work on the X# runtime, which will consist of a set of runtime functions, xBase datatypes RDDs, Macro compiler and more.

We expect to be able show you a lot of this at the XBase Future conference in Cologne end of April.

Will we see you there ?

Winter is coming

Earlier this year, around the conference in Cologne, we have published a roadmap in which we told you about our plans and what we wanted to deliver in 2016. In this week before Christmas, with winter on our doorsteps it is time to look back and see what we have achieved.

As we all now, predicting the future is very difficult. Who whould have predicted that Donald Trump would be the next president in the US?

So we were wrong in our predictions about the progress of X# too.  But we are on the right track, and we are the only XBase dialect that is making great progress every month.

What we did achieve in the 15 months behind us is:

  • A fully functional core dialect compiler based on the Roslyn source, that can compile everything that you can find in C# 6 with an XBase language syntax.
  • Many new features have been added to the xBase language, such as LINQ, Anonymous types, support for Asynchronous operations, creating generics etc. You only have to look at the pearls section in our forums to see proof of that. Every niche corner in the LINQ area in our product is being tested at length by Phil, and it simply works. Other customers have used other new features and we have received a lot of positive response on the new features
  • The support for the VO and Vulcan specific datatypes and language constructs is also almost finished. Last week we have added some missing features, such as support for PCALL() to call native Win32 functions through a pointer in an external DLL. Not something that you use in your everyday development but it is used in some inhouse libraries as well as in the VO SDK. So we decided that add that to our language, to make the migration from VO and Vulcan as smooth as possible.
    "Normal" VO and Vulcan applications compile fine now with X#.  We have done that ourselves and we got some very positive feedback from our customers who have also successfully migrated apps.
  • We have working Visual Studio integration in both Visual Studio 2015 and Visual Studio 2017. We are very proud that we were one of the original "sim ship partners" (the last one in the alphabetical list)that released their support for Visual Studio 2017 on day one.
