The most significant changes involve modifications to the `StrongRefe…

…renceMessenger.Default.Send` and `StrongReferenceMessenger.Default.Register` method calls in `MainWindow.xaml.cs`, `MainViewModel.cs`, and `SitemapViewModel.cs`. These methods now include additional arguments related to the sitemap name. Additionally, the `StrongReferenceMessenger.Default.Unregister` method call was removed from `MainViewModel.cs`. Lastly, several build properties were removed from `openHAB.Windows.GeneratedMSBuildEditorConfig.editorconfig`, indicating potential changes in the project configuration or build process.

List of changes:

1. The namespaces `System` and `System.Threading.Tasks` were removed and then added back in `MainWindow.xaml.cs` and `SitemapViewModel.cs`. This could be due to reordering of the namespaces.
2. The `StrongReferenceMessenger.Default.Send` method calls in `MainWindow.xaml.cs` were modified to include `Vm.SelectedSitemap.Name` as an additional argument.
3. The `StrongReferenceMessenger.Default.Register` method calls in `MainViewModel.cs` and `SitemapViewModel.cs` were modified to include the sitemap name as an additional argument.
4. The `StrongReferenceMessenger.Default.Unregister` method call in `MainViewModel.cs` was removed.
5. The `StrongReferenceMessenger.Default.Send` method calls in `SitemapViewModel.cs` were modified to include `Model.Name` as an additional argument.
6. Several build properties were removed from `openHAB.Windows.GeneratedMSBuildEditorConfig.editorconfig`. This could be due to changes in the project configuration or build process.
