ERROR_SXS_DUPLICATE_DLL_NAME
ERROR_SXS_DUPLICATE_DLL_NAME means that two components referenced directly or indirectly by the active manifest graph contain files with the same DLL name. Windows cannot choose one safely when both assemblies contribute the same named binary to the active side-by-side context.
How to investigate
- Use the dependency trace to identify both assemblies that contribute the duplicate DLL name.
- Correct the package so the application graph selects one compatible assembly instead of embedding competing copies.
- Do not delete a DLL only by filename until its manifest ownership and dependent modules are understood.
This is a conflict in the active assembly graph, not a normal DLL search-order decision.
