The GeneXus standard classes are a set of routines, written in native code, that are referenced by the generated code. As an example, the code to send an e-mail is not generated in every object that sends e-mails. It is "packed" as part of the Standard Classes and referenced by the generated code.
Every GeneXus Generator has its set of Standard Classes.
Standard Classes in an executable format are distributed on every GeneXus version and are automatically installed.
Standard Classes source code is _not_ distributed with GeneXus for many generators (see below). .NET and .NET Core standard classes can be reached from https://github.com/genexuslabs/DotNetClasses and Java standard classes from https://github.com/genexuslabs/JavaClasses
Releases for each GeneXus release
You can download (if required), change and redistribute the Standard Classes source code. For details see
Depending on the generator, those routines are packaged differently.
Refer to https://github.com/genexuslabs/JavaClasses#how-to-compile and https://github.com/genexuslabs/JavaClasses#modules
The already packaged routines are located on the <GeneXus Installation>\gxjava folder as gx*.jar.
Refer to https://github.com/genexuslabs/DotNetClasses#how-to-build and https://github.com/genexuslabs/DotNetClasses#modules
The already packaged routines are located on the <GeneXus Installation>\gxnet and the <GeneXus Installation>\gxnetnetcore folders as gx*.dll.
In order to execute any iSeries (Cobol|RPG) program, you need to install the GeneXus iSeries Library; the standard GeneXus routines used by the GeneXus Cobol and RPG programs.
The GeneXus Standard Classes for Android together with what we call the Android FlexibleClient (which is a set of Android libraries) are packaged in binary format in a Maven Repository inside Genexus installation directory (in Android/m2Repository). You may also access the sources (in Android/Sources), modify them and apply changes. For more information on how to modify the FlexbileClient please read the CONTRIBUTING.md (in Android/Sources).
The GXFlexibleClient framework is the iOS GeneXus standard classes deployed as a framework that is referenced in your Xcode project. You will notice it is copied and installed in the MAC machine during the compilation process.
