How to get current user, and how to use User class in MVC5?

Question

• How can I get the id of the currently logged in user in MVC 5? I tried the StackOverflow suggestions, but they seem to be not for MVC 5.
• Also, what is the MVC 5 best practice of assigning stuff to the users? (e.g. a User should have Items. Should I store the User's Id in Item? Can I extend the User class with an List<Item> navigation property?

I'm using "Individual User Accounts" from the MVC template.

Tried these:

• How do I get the current user in an MVC Application?
• How to get the current user in ASP.NET MVC
• Get logged in user's id - this throws the following:

'Membership.GetUser()' is null.

If you're coding in an ASP.NET MVC Controller, use

using Microsoft.AspNet.Identity;

...

User.Identity.GetUserId();

Worth mentioning that User.Identity.IsAuthenticated and User.Identity.Name will work without adding the above mentioned using statement. But GetUserId() won't be present without it.

If you're in a class other than a Controller, use

HttpContext.Current.User.Identity.GetUserId();

In the default template of MVC 5, user ID is a GUID stored as a string.

No best practice yet, but found some valuable info on extending the user profile:
