The public beta 8 of X# Bandol is now also available for download.

A few months ago we posted a message on our forums under the title "The X# devteam wants to meet you". The reponse to that has been very positive, so we have decided to organize the event. With the help of Greg Garza and his colleagues at QLAdmin Solutions we have booked a location and we are now finalizing the plans.

We have decided to name this the "X# Summit".

It will be held in Austin (Texas) and will be on Thursday March 21 and Friday March 22 2019 . Please block those dates in your calendar if you want to attend.We will post more information later this week with details about the schedule, how you can register, what the costs will be, how you can reserve a room at the hotel for a special price that we arranged etc.

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).
Of course there will also be plenty of time for questions and answers and to socialize with other XBase developers, exchange ideas and maybe make plans to work together.

We intend to be there with 2 people from the development team, but we are also looking for other speakers. If you are interested then you can fill a complete time slot, but it would also be great if you want to share a success story of a project that you did. Our idea is to have one time slot where people can show their applications ("Application Show"). We have done this on other events in the past and this was always very inspiring.

We did want to share this with you so you can discuss a possible trip to Austin with your family during the Christmas holidays. So why don't you come and bring your partner for a nice (romantic?) weekend after the conference.

Once again, on behalf of the entire X# development team a very happy Chrismas for you and your loved ones.

A short message to inform you of things we are working on this moment.

  • We are making good progress with the new macro compiler. Most of the features are ready. And performance is very good !
  • We have located and fixed almost all of the issues (some of) you have reported with the X# runtime
  • We have added support in the compiler for the Xbase++ dialect.
  • We have fixed many things in the VS integration. And X# also installs and works with the new Visual Studion 2019 preview
  • We have also rearranged the runtime to better support the Xbase++dialect. There is now a separate VO assembly and a XPP assembly. Both share a common RT assembly that contains the common code (such as the USUAL, DATE and FLOAT types)
  • We have updated the compiler to the latest version of the Roslyn source code. As a result we have new features (such as the ability to generate reference assemblies ), the new combination of "PRIVATE PROTECTED" which makes a type member only accessible for derived classes in the same assembly and more.
    We have not enabled all the new features of the latest C# versions yet. For some of them we still have to invent a syntax. We are considering to add the IN modifier for parameters in one of the next builds. This will declare a readonly reference parameter. This is especially useful when you have a structure as parameter of a method (like the FLOAT or USUAL structures in the runtime). This should result in somewhat faster execution speed since at runtime not the whole structure has to be passed to a function or method, but only the address of the structure. Once we have added this to the compiler then we will also start to use this in the runtime.
    There are many other new features added to Roslyn. You can look at this page to see the new features in C# in the last versions.
    If you see something that you think is useful for X#, please let us know. And if you have a suggestion for a syntax, that helps too. One other thing we are thinking about is the "is pattern", which combines the "IS" check with the "ASTYPE" operation and creates a variable that has the scope of the IF expression that it is part of :

    IF oServer IS DbServer oDbServer
    oDbServer:GoTop() /// <- this will generate a compiler error because the scope of oDbServer is the statementblock inside the IF expression

We expect a new FOX release of the product by the end of next week. A public release will follow short before Christmas

We are very proud that we can announce that we have just released XSharp Bandol 8 "The Christmas Edition" to our FOX subscribers.
A public version of this beta will be released in a few days,

This new version has many new features. To name a few:

  • A new much faster macro compiler
  • Many changes to the runtime, including new functions and improved RDD support
  • The compiler has been created from the latest version of the Roslyn code. Some of the new Roslyn features, such as the abiltity to create reference assemblies by specifying a command line option have been added. Other new features will follow in the coming releases
  • We have added support for a new dialect "Xbase++". The compiler now recognizes the "Xbase++ syntax for class declarations.
  • We have added a new .Net core version of the compiler and X# scripting engine (which replaced the former "portable" compiler.
  • And many more

The development team wishes you all a very happy Christmas.
