PersistentComponentState with a CSLA ReadOnlyList

[saulyt]

I am trying to get the PersistentComponentState service working in my Blazor Web App. I have a ReadOnlyList that is loaded into my vm.Model in the OnInitializedAsync method. I am trying to persist it so that when the component is re-rendered when web assembly is available, it will not have to reload the model from the server. The problem is that when I call ApplicationState.PersistAsJson I get an error that my type is abstract, an interface, or is read only, and could not be instantiated and populated. The error makes sense as this is a ReadOnlyList. I was wondering if anyone knows a simple, relatively painless work around for this.

CSLA objects can't be serialized into and out of JSON directly. You need to convert them into a byte array or string by using MobileFormatter, and then put that value into the persistent component state API.
