EF and EF Core DbContext types implement IDisposable. As such, best practice programming suggests that you should wrap them in a using() block (or new C# 8 using statement). Unfortunately, doing this, at least in web apps, is generally a bad idea.

• Use BindAttribute on the action method 
• Use [Editable] or [BindNever] on the model 
  
• Use two different models 
• Use a base class 
  
• Use ModelMetadataTypeAttribute 
  
• Explicit binding via TryUpdateModelAsync<> 
  

This was a very quick run down of some of the options available to you to prevent mass assignment. Which approach you take is up to you, though I would definitely suggest using one of the latter 2-model approaches. There are other options too, such as doing explicit binding via TryUpdateModelAsync<> but the options I've shown represent some of the most common approaches. Whatever you do, don't just blindly bind your view models if you have properties that should not be edited by a user, or you could be in for a nasty surprise.

And whatever you do, don't bind directly to your EntityFramework models. Pretty please.
