ERROR_SXS_MISSING_ASSEMBLY_IDENTITY_ATTRIBUTE

ERROR_SXS_MISSING_ASSEMBLY_IDENTITY_ATTRIBUTE — The assemblyIdentity element is missing an attribute required in this activation context.

An assembly identity is how Side-by-Side activation distinguishes assemblies. A required identity attribute was absent, so Windows cannot bind the requested dependency reliably.

The trace identifies the manifest being read. Compare the identity in that manifest with the identity expected by the application or policy manifest.

What to check

Check required identity fields such as name, version, processorArchitecture, publicKeyToken, language, and type where the manifest schema requires them.
Use the manifest that was shipped and tested with the assembly; do not invent identity values to suppress the error.
Rebuild or reinstall the affected private assembly after correcting the manifest.
