In my project web Asp.net core 3.1. I have a view component to generate head navigation for my website but when I invoke it into _Layout.cshtml page I got an error: The model item passed into the ViewDataDictionary is of type '', but this ViewDataDictionary instance requires a model item of type ''
System.InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'Models.HeaderModels', but this ViewDataDictionary instance requires a model item of type 'Models.BannerMenuModel'.

This error occurs when the model return in InvokeAsyn() method not the same as the model declare in your view.
Model in view is
BannerMenuModeland model return in your InvokeAsyn() isHeaderModels. Please make sure they are the same model.
