Warning BE0008: Namespace '[namespace]' excluded via namespace comments conflicted with API filter setting. Exclusion ignored.
This warning occurs if a namespace in the NamespaceSummaries project property is marked as excluded but the ApiFilter has it marked as included. In such cases, the API filter wins and the namespace is included in the help file.
Edit either the NamespaceSummaries property or the ApiFilter property such that the exclusion setting for the indicated namespace matches in both. If you want to exclude an entire namespace, the preferred way is to use the ApiFilter project property. Excluding namespaces via the NamespaceSummaries property is supported for backward compatibility with older projects.
