MVVM pass/bind value form ViewModel to ViewModel of parent View without using constructor

I've a shared core project(contains ViewModels) between WPF and [login to view URL] apps(each one contain it's views and interface implementations) It's a .NetStandard class library using Prism.Core. In this Project I've tow ViewModels for two views: TabItem=TabItemViewModel, BrowserView=BrowserViewModel <TabItem xmlns="[login to view URL]" ............. prism:ViewModelLocator.AutoWireViewModel="True" Header="{Binding Name}"> <local:BrowserView /> <TabItem> public class TabItemViewModel : INotifyPropertyChanged { public string Url {get; set} // shortened for clarity // ..... } public class BrowserViewModel: INotifyPropertyChanged { public string Url {get; set} // shortened for clarity // ..... } How to pass the url between the two ViewModels?? The app is browser like with multiple tab instances. I don't want and I can't use the viewmodel constructor like new viewmodel(url) for business logic considrations. I've read suggestion to use dependency property, but I can't define it in the viewmodel as it requires using [login to view URL]; and the viewmodel only uses .netstandard and prism.core. other suggestions to define dependancy property in the code behind [login to view URL] but I could not get it working. I need to sync multiple properties not only url. I need working sample code
