WixToolset.WixStandardBootstrapperApplicationFunctionApi

WixToolset.WixStandardBootstrapperApplicationFunctionApi contains the SDK for building BAFunctions extensions for WixStdBA, the WiX Standard Bootstrapper Application for Burn bootstrapper bundles.

BAFunctions are native-code DLLs (typically written in C++) that let you supplement the behavior of WixStdBA, rather than writing an entirely new BA to tweak existing BA behavior.
