Scripting Using External Assemblies
Scripting with external assemblies is the preferred way to use scripting in Microsoft BizTalk Server. External assemblies provide several advantages:
Easy code sharing
Simpler maintenance
Easier debugging
Note
Test Map fails if the Scripting functoid uses an external assembly which is not registered in the GAC. It works if the external assembly is in the same bin folder as the current project's assembly (placed after build).
Re-using the script only requires setting the Script property of the Scripting functoid. Because the script is stored outside of the map, you can modify the script without changing the map. And you can use the full array of Visual Studio debugging tools to ensure your script runs correctly.
Warning
The code in the external assembly must be thread-safe. Under stress conditions, multiple instances of a map may be running concurrently.
For a sample function housed in an external assembly, see XML Tools (BizTalk Server Samples Folder).
