### Remarks

The same default references that are added to scripts inside the Assets folder are added the assembly build. This property returns the default references.

The default references are in part controlled by [AssemblyBuilder.flags](/engine/6000.6/script-reference/unityeditor/compilation/assemblybuilder/flags.md), [AssemblyBuilder.buildTarget](/engine/6000.6/script-reference/unityeditor/compilation/assemblybuilder/buildtarget.md) and [AssemblyBuilder.buildTargetGroup](/engine/6000.6/script-reference/unityeditor/compilation/assemblybuilder/buildtargetgroup.md).
