Hi,
I'm trying to build Firewall ext from
https://github.com/wixtoolset/Firewall.wixext
Getting a compile error.

3>  FirewallWindowsInstallerBackendExtension.cs(10,61,10,97): error CS0246:
The type or namespace name 'BaseWindowsInstallerBackendExtension' could not
be found (are you missing a using directive or an assembly reference?)
3>  FirewallWindowsInstallerBackendExtension.cs(14,46,14,71): error CS0115:
'FirewallWindowsInstallerBackendExtension.TableDefinitionsForTuples': no
suitable method found to override

What am I missing?

Adnan Shaheen.
