I have a solution that has many different RCL projects (Main solution is.Net 8 Blazor using InteractiveServer) Each one of the RCL’s has pages in it. I define a page as a component with @page "/someurl"

You used to just load the assemblies from the other projects via the AdditionalAssemblies property on the Router like so

<Router
    AppAssembly="@typeof(App).Assembly"
    AdditionalAssemblies="{ Load Them Here}">
    <Found Context="routeData">
        <AuthorizeRouteView RouteData="routeData">
            <NotAuthorized>
                <RedirectToLogin />
            </NotAuthorized>
        </AuthorizeRouteView>
        <FocusOnNavigate RouteData="routeData" Selector="h1"/>
    </Found>
</Router>

However, that no longer works? I looked on Github and a number of people had the same issue, with a few comments from Microsoft developers saying to load the assemblies like so and it will work

app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode()
    .AddAdditionalAssemblies(ExtensionManager.GetAssemblies());

Well I have tried both and neither way works? When I browse to the URL I get a 404 (page can’t be found)

Any idea how to get this working as this is a huge problem for me 🙁
