public string[] additionalReferences { get; set; }
```

### Remarks

By default the same references that are added to scripts inside the Assets folder are added the assembly build. This property allows to add additional references. References paths are relative to project root and must include full filename with .dll extension.

The default references are in part controlled by [AssemblyBuilder.flags](/engine/6000.5/script-reference/unityeditor/compilation/assemblybuilder/flags.md), [AssemblyBuilder.buildTarget](/engine/6000.5/script-reference/unityeditor/compilation/assemblybuilder/buildtarget.md) and [AssemblyBuilder.buildTargetGroup](/engine/6000.5/script-reference/unityeditor/compilation/assemblybuilder/buildtargetgroup.md).
