Migrating from Microsoft.Tools.WindowsInstallerXml.Bootstrapper (WiX v3) to WixToolset.Mba.Core (WiX v4)

Question

Hi,

I am using a managed bootstrapper with BootstrapperCore.dll in WiX Toolset v3.14, and I am considering upgrading from WiX Toolset v3 to WiX Toolset v6.
According to another discussion,, the upgrade should be done step by step.
I understand Supported upgrade sequence:
v3 → v4 → v5 → v6
(Direct upgrades such as v3 → v5 are not supported.)
I plan to use WixToolset.Mba.Core instead of BootstrapperCore.dll when migrating to WiX v4.
However, I found that the following event methods have been removed:

• OnSystemShutdown
• OnDetectPriorBundle
• OnDetectCompatiblePackage
• OnDetectTargetMsiPackage
• OnPlanCompatiblePackage
• OnPlanTargetMsiPackage
• OnApplyPhaseCount
• OnElevate
• OnResolveSource
• OnRestartRequired
  A few of these methods are explained how to use in WiX Toolset v4, but most of them are not documented or explained in WiX v4.
  I would like to know how to replace them in wix v4.

Best regards.

Documentation for creating a custom Burn BA is sorely lacking. The FAQ provides most of the information, and some of them have minor renames that were probably missed because they were small (like OnDetectCompatiblePackage changed to OnDetectCompatibleMsiPackage because it only applies to MSIs).
