best practices for 'The model item passed into the dictionary is of type' scenarios when using ASP.NET Core Razor Pages with ViewModels?
I'm working on a project and hit a roadblock. I've looked through the documentation and I'm still confused about I've been banging my head against this for hours... I'm currently working on an ASP.NET Core 6 Razor Pages application, and I've run into an scenario when trying to pass a ViewModel to my Razor page. I have a ViewModel that includes both a list of items and a single item. When the page is rendered, I receive the behavior message: "The model item passed into the dictionary is of type 'YourNamespace.Models.YourViewModel', but this dictionary requires a model item of type 'YourNamespace.Models.YourExpectedModel'". I've attempted to rectify this by ensuring that my page model is correctly set up to accept the ViewModel. Here’s the relevant portion of my code: ```csharp public class MyPageModel : PageModel { public YourViewModel ViewModel { get; set; } public void OnGet() { ViewModel = new YourViewModel { Items = // fetch items, SingleItem = // fetch single item }; } } ``` And in my Razor Page: ```html @page @model MyPageModel @{ var items = Model.ViewModel.Items; } <ul> @foreach (var item in items) { <li>@item.Name</li> } </ul> ``` Despite having the correct model set in my `PageModel`, I’m still seeing that behavior when I load the page. I’ve also tried specifying the model in the Razor view with `@model YourNamespace.Models.YourViewModel` to match the type of `ViewModel` in my page model, but it results in the same behavior. I’ve double-checked the namespaces and everything seems fine. Any suggestions on how I can resolve this scenario? Is there something specific I might be missing regarding how Razor Pages binds models? This is part of a larger application I'm building. I'd really appreciate any guidance on this.
