Part 15 : What is ViewModel in .NET Core MVC ?
In .NET Core, a ViewModel is a class specifically designed to represent data that the view (UI layer) needs to display. The ViewModel serves as a bridge between the Model (the application's data structure or business logic layer) and the View (the UI). This pattern is particularly useful in ASP.NET Core MVC and Razor Pages, where it facilitates separating concerns and organizing data for display purposes.
Key Points about ViewModel
ViewModel contain fields that are represented in the view (for LabelFor, EditorFor, DisplayFor helpers)
ViewModel can have specific validation rules using data annotations.
ViewModel can have multiple entities or objects from different data models or data source.
