Cannot find view for Cocktail.DialogBase

I have followed the advice in the Dialogs and Messageboxes topic on the Ideablade website in order to create a simple Dialog Box with its own viewmodel and view.

After I issue the command: "await _dialogManager.ShowDialogAsync(_namePrompt, DialogButtons.OkCancel);" I get back the error "Cannot find view for Cocktail.DialogHostBase", also in the VS 2012 output window is:

System.Windows.Data Error: 5 : Value produced by BindingExpression is not valid for target property.; Value='<null>' BindingExpression:Path=DisplayName; DataItem='DialogHostBase' (HashCode=43089040); target element is 'Window' (Name=''); target property is 'Title' (type 'String')

The ViewModel and View correctly follow the naming conventions. As a test I can display the control in question embedded on a MainPage - this confirms that Caliburn Micro can fins the view from the viewmodel normally, it just does not work from the dialog manager.

I'm a bit confused. Did you subclass Cocktail.DialogHostBase? You only need to do that if you plan on customizing the dialog host. This is not required for a simple dialog. All you have to do is create a ViewModel and View for the content you want to display in the dialog and call _dialogManager.ShowDialogAsync() with it. Cocktail will do the rest. If you look at TempHire you won't find a custom DialogHostView.

Here's the example in form of a WPF application. It works as expected. I'm not sure what's going wrong in your case. Maybe you can compare the sample to what you have. Something must be different. The solution should automatically download the necessary NuGet packages when you build. If you get an error, make sure you allow NuGet to download missing packages in the Package Manager Settings.

Thanks for letting me know. Cocktail is supposed to always be included even if you change the SearchPatterns. Sounds like that isn't working anymore. Something to investigate I suppose.
