Ooops. We need a .changes file here please.

Can we implement some kind of solution to merge two wix files? This solution is a little scary since the user would have trouble maintaining Tauri changes.

[Cupnfish]

I haven’t come up with any other ideas yet, but I think this feature is necessary, so if anyone has a better idea, feel free to share.

I need to try merging two XMLs using serde, but i'm busy with the plugin system right now.

[Cupnfish]

Do I need to close the PR?

[lucasfernog]

Let's wait to see if I can come up with a solution that simplifies your life :)

[lucasfernog]

I think using Fragments is the right way to do this.

[lucasfernog]

I've finished implementing Wix fragments support. We can also add support to WIX include files if you need.

[Cupnfish]

Thank you for your help.
It’s great, I love it. WIX include files is necessary.
In addition, I still have a problem to solve, the current WIX template is the default download edge webview, for other rust projects do not need this, packaging with this is very inconvenient, there is no way to solve this problem?
I think I should mention a new issue.
#1606

Since you're using the bundler outside Tauri, i think we can reconsider this :)

[lucasfernog]

If we start getting attention with the bundler as a library, we should consider moving it to its own repo.
