Wix Toolset version 5 with Managed BootstrapperApplication (created in .NET Framework 4.8). The burn variable "RebootPending" always returns 1

[harshmodhiya]

We had created a Managed Bootstrapper Application with the below version:

• MBA - .NET Framework 4.8.1
• WiX toolset - 3.14

Now, we are in the process of upgrading our WiX project (both Bundle and Setup project) from version 3.14 to version 5 using FireGiant's HeatWave extension in Visual Studio 2022.

After the upgrade, we consistently observe the burn variable RebootPending displaying a value of 1, which is incorrect.

Here's the scenario in our application:
We install .NET Framework 4.8.1 as a prerequisite if it's not already installed on the user's PC. After the installation, we receive a restart required status. We provide the user with two options:

• Restart now
• Restart later

If the user chooses the "Restart later" option but does not restart the PC and attempts to reinstall our application again, we need a status similar to "RebootPending. to inform the user like restart is required.

We have observed that "RebootPending" was added in commit Include RebootPending
and then removed in commit Removed RebootPending

Need help with the below,

• With the new WiX how BA captures reboot is required or not?
