Marshal
The Marshal package contains the engine (marshal.dll) for exporting, and importing, data objects using Marshal ETL models. Design your model in Marshal Studio, then use this package to execute it, as part of your own application.
Once the package is in your Visual Studio solution, you may use the Marshal.API namespace. There are other namespaces in the assembly, refrain from using them, since they expose higher complexity, and could be subject to future changes.
