-## Check if a package is generated
-
-If a library is packable (check for the `<IsPackable>true</IsPackable>` property) you'll need to set `<GeneratePackageOnBuild>true</GeneratePackageOnBuild>` in the source project. That is necessary as packages aren't generated by default in servicing releases.
-
-## Determine ServiceVersion
-
-When you make a change to a library & ship it during the servicing release, the `ServicingVersion` must be bumped. This property is found in the library's source project. It's also possible that the property is not in that file, in which case you'll need to add it to the library's source project and set it to 1. If the property is already present in your library's source project, just increment the servicing version by 1.
