How are the UCs copied to the application directory?

UCs are installed in the GX installation directory (i.e. UserControls\UserControlName) and all the UCs being used by an application are automatically copied from the GeneXus Installation directory to the application directory (e.g. CSharpModel\Web\UserControlName). 

Note: This copy is done during the build process.Once each User Control being used is copied, a file named “UserControlName.versionId.ver” is created in the application directory (e.g.  CSharpModel\Web) in order to avoid copying the UCs again.

When providing UCs, it is advisable to include the tag “<Version>Number</Version>” in the UserControlName.control file. If this recommendation is followed, the newer version of the user control is copied to the application directory once the UC installation process is complete (i.e. “genexus.exe /install” execution) and building the application.
