By default this generates the C# source code to allow you to incorporate the transform into your own project.
You can also select the 'Generate a Compiled Application (.exe) option in the 'Debugger Configuration' dialog box. When you click 'Compile', this will then compile the transform into a .Net application for you which you can then distribute.
You can change the "OutputFileName" and "SourceFileName" used by the compiled .Net Application by passing in command line parameters.
DataTransformationApp.exe /SourceFileName="c:\temp\mydata.xml" /OutputFileName="c:\temp\myoutput.xml"
You also need to distribute the Liquid Data Mapper runtime file from:
[Liquid XML Install Path]\DataMapperRedist\LiquidTechnologies.DataMapper.Runtime.dll.
If you want to run the transform Linux, you would need to ensure the Mono .Net package is installed on the Linux box so you can run the compiled .Net application.
