I have a WIX project that originally was created with WIX version 2, after migrating the project to WIX version 3 I had a lot of unresolved reference to symbols like Dialog.CancelDlg, Dialog.BrowseDlg, etc...
If I add the reference to WixUIExtension these symbols resolves, but I get another unresolved symbols in WixUIExtension itself:
Unresolved reference to symbol 'Property:WixAppFolder' in section 'Fragment:' in UIExtension\wixlib\InstallScopeDlg.wxs
Unresolved reference to symbol 'Property:ApplicationFolderName' in section 'Fragment: in UIExtension\wixlib\WixUI_Advanced.wxs
I tried to add the references to all available extensions, but this did not help.
While writing this post, an idea came to me: probably I should define them by myself somehow?
