What happens

My project has ViewModel and View base classes that provide, amongst other things, some common interactions to all the derived views and view models.

I recently updated from ReactiveUI.Blazor.Reactive 24.2.0 to 26.2.1 and after fixing various other issues related to breaking changes, I am left with CS0450 compiler errors in generated code.

I think the key to the problem is the definition of my generic view base class:

class View<TViewModel> : ReactiveComponentBase<TViewModel> where TViewModel : ViewModel

It looks like the error is caused by the source generator adding a class type constraint on top of the ViewModel constraint when generating interaction bindings between the view and view model base classes.

What you expected instead

Generated code should compile.

Steps to reproduce

Exception and stack trace

On compiling the MWE project, the compiler reports:
`'ViewModel': cannot specify both a constraint class and the 'class' or 'struct' constraint`
