+## Client Build Notes

+### Database Migrations
+
+Since EF core needs all dll files to be present, including Dalamud ones,
+there's a special `EF` configuration that exempts them from setting
+`<Private>false</Private>` during the build.
+
+To use with `dotnet ef` commands, specify it as `-c EF`, for example:
+
+```shell
+dotnet ef migrations add MigrationName --configuration EF
