## Remarks

During a build, the [IShouldIncludeInBuildCallback.ShouldIncludeInBuild](/engine/6000.0/script-reference/unityeditor/packagemanager/ishouldincludeinbuildcallback/shouldincludeinbuild.md) method is invoked on each managed plugin (DLL) inside the package whose name is [IShouldIncludeInBuildCallback.PackageName](/engine/6000.0/script-reference/unityeditor/packagemanager/ishouldincludeinbuildcallback/packagename.md).

Register your implementation with the Package Manager using RegisterShouldIncludeInBuildCallback. You can only register one implementation of this interface per package.
