Crash with MVVM and code behind.

[FraserElectronics]

I am struggling using MAUI with the MVVM code pattern using Visual Studio Version 17.5.0 Preview 1.0.
I have my views and view models and register them with the service container then in my view code behind I use constructor injection to pass in the view model which I then set the BindingContext to.
If I run as a Windows application I get a really helpful (not!) crash message.

If I run the same code under the Android emulator I get a much more helpful error message (note, I have all exceptions enabled in Visual Studio):

I see many examples of constructor injection into the view code behind so I don't understand why I need a parameterless constructor.

Can anyone point out what I am doing wrong?

Never mind, I forgot to register my routes 🤦‍♂️
