HarvestFile Target
The HarvestFile target passes HarvestFile items to the
HeatFile task to generate authoring from a file. Authoring is generated
for type libraries and self-registration from DllRegisterServer. This
target is processed before compilation. Generated authoring is automatically added
to the Compile item group to be compiled by the Candle task
<ItemGroup> <HarvestFile Include="comserver.dll"> <ComponentGroupName>COM</ComponentGroupName> <DirectoryRefId>ServerDir</DirectoryRefId> </HarvestFile> </ItemGroup>
The following tables describe the common WiX MSBuild properties and items that are applicable to the HarvestFile target.
