Need to improve ResourceDictionary support #36
Description
A real-world project might use lots of ResourceDictionary in raw .axaml files. XamlX compiles them so they can be consumed elsewhere in the project.
Right now, ASXG misses them. This branch shows the error if you dotnet run the test project.

A quick workaround via manual steps is shown below.

Hope this can be investigated and fixed soon, but Project Rover can already run very well with the same workaround, so a big milestone on compatibility has been achieved.
