Share ViewModel with Maui and BlazorWebView

[johngsandiford]

Hi. I have a MAUI app that mixes MAUI controls and BlazorWebViews. I want to be able to share a view-model (i.e. the same instance) between both the MAUI part and the Blazor part, but I can't figure out how to share it.

Some view-models are one per SPA, but others are created dynamically.

Any help much appreciated. Thanks, John

I got the same problem. For pages with ViewModels registered as singletons, you could inject it into the Blazor component. Does anyone have a solution for transients?

you can pass an existing ViewModel to the BlazorWebView. It can be retrieved via a CascadingParameter
