How is ReactiveViewModelMappings generated

[HakanL]

I'm analyzing this sample to use as a starting block for my own application. There is one part that I can't figure out, how is the the ReactiveViewModelMappings file generated? I can see the generated file, but when I copy the Todo solution this file is not generated any more. I've tried to search for source generators, etc, and I can see that there is a reference to the Uno.SourceGenerationTasks nuget package, but I can't find any other references to how this file is generated. Can someone please fill me in how this file is generated? It's referenced in this line:
https://github.com/unoplatform/uno.todo/blob/main/src/ToDo.UI/App.xaml.host.cs#L64

The file is generated by the FeedsGenerator in the Uno.Extensions.Reactive package.

To get it generated you only need to install that package and have a class named <Something>ViewModel. It will contains a mapping between the VM you declared and the class that has been generated from it which is more "bindable friendly" (public methods are converted to ICommand and IFeed properties are exposed as basic properties).

If you are not planning to use feeds, you can just remove the ReactiveViewModelMappings.ViewModelMappings argument on your referenced line.

I did upgrade all the Uno dependencies to latest version 2.2.0, and in the Todo app it was 2.1.0-dev.184, is it possible something changed in 2.2 on how it finds the view models?

No, nothing should have changed regarding VM resolution since few months.

I just realized that your VM class must also be partial.

Otherwise, are you able to share the code with us? I'm not sure I understand your setup.

It's a private repo on Bitbucket, but I'm happy to share it with you, I just can't make it public (once it's set for private I can't change it). It doesn't contain anything sensitive. Do you have a user on Bitbucket and I can invite you?

[dr1rrb]

Yes I do, my username is dr1rrb. I think that you will need my account's email, but I rather not make it public here. So you can send an email to info@platform.uno (not an invitation: there is no bitbucket account associated to that email), then I'll be able to send you my bitbucket account email (quite complex process :P )

Thanks, yes I think I need an email. I sent you an email and let's go from there. Really appreciate the help!
