SSIS: Auto-Rebuilding SSIS Script Tasks/SSIS Components to Sync Stale References
Coming from a stronger C# background, I instinctively reach for helper classes to maintain DRY (Don't Repeat Yourself) principles. That instinct served me well until I carried it into SSIS. When I needed to reuse logic across packages, I did the natural thing: I built a shared DLL and registered it in the GAC on the server. It worked fine until I needed to add more optional arguments or change the data type of the argument to the existing method. Every time I need to update that assembly and re-import it, my packages break with a DTS Script Task: Runtime Error. The reason caught me off guard: the precompiled script binaries inside each package were still bound to the old version of the DLL, and a normal build never recompiles them. In today's post, I'll walk through how I tackled this by building a console application that rebuilds the Script Tasks and Script Components automatically.
