Online session: What does the compiler do ?

: 04 December 2021

Coming Thursday (December 9th) we will have an online session in which we will try to explain what X# compiler does with your code. We will discuss several topics, such as

Strong Typed versus weakly typed functions / methods
Different calling conventions (Clipper - Strict - Pascal - Thiscall)
Function / method overloading
Values types versus reference types
Parameters by value and parameters by reference
Early bound code versus late bound code
Virtual instance methods versus non virtual methods

The session will mostly use code from the XSharp Runtime as example and will look at that code from the Xbase side but will also look at the produced IL code using the ILSpy decompiler. We will also discuss 'ease of use' versus 'best performance'.

Update We have re-recorded the session. Is is now available in our youtube channel

The example can be downloaded here:

Visual Studio 2022 support for X# (experimental)

: 01 December 2021

We have uploaded a first version of our support for Visual Studio 2022. This also includes support for packagereferences inside the project file.

Known issue: the intellisense engine does not yet include the assemblies that are listed inside a nuget package.

For example: if you have a Console application and remove all references and replace that with a Nuget Package reference for System.Runtime then that project will compile and run, but the editor will not be able to show tooltips, code completion etc for types like System.String, System.Console etc.

XSharp on Dutch Television - We believe in Open Source

: 13 October 2021

We had promised to publish the link to the TV item that was broadcasted on October 2 and October 5 on Dutch Television.
In this TV item we have tried to explain why we think that Open Source software is important and helps people to secure their investment in software for the future.

We have recorded this item in cooperation with Oliver Gr├╝n, from Gr├╝n Software Group from Aachen, Germany and some of the employees of his company.

Online session: The X# preprocessor

: 17 September 2021

On Thursday September 30 we will have another online X# session. The topic for this session will be the X# preprocessor and how you can use User Defined Commands (UDC) to simplify your code.
For developers with a Clipper or Xbase++ background the preprocessor will probably have no secrets.
For other developers the preprocessor will be something that they have heard of but most likely have never really used.

The session will cover topics such as:

when to use UDCs
what is the difference between #command, #xcommand, #translate and #xtranslate
match markers and result markers
#include files
conditional compilation using #ifdef
predefined preprocessor macros

We will also show some examples from the X# header files and from the X# runtime source code.

The session will be presented by Robert and will start at 16:00 CEST.

The video of this session is in our youtube channel: https://youtu.be/qvbqxGt0zgQ
