I am learning MVC (MVC4) for the first time and completing the MvcMusicStore tutorial from http://www.asp.net/mvc

The tutorial is written for MVC 3 and as I am writing the following code (in my MVC4 project)

@Html.ActionLink(album.Title, "Details", new { id = album.AlbumId })

visual studio is automatically inserting ‘object’ after I type new { to give me:

@Html.ActionLink(album.Title, "Details", new object{ id = album.AlbumId })

Is one way more correct than the other or is it a difference in MVC versions to have more defined code?

    The syntax

    new object{ id = album.AlbumId }

    should yield a compiler error because “id” is not a property of object.

    The syntax 

    new { id = album.AlbumId }

    is correct. It creates an anonymous type with a property called id

    Note that in a view, you will not get a compiler error at compile time (counter-intuitive as that may seem). The view is compiled at runtime. You may see a red squiggle under the error in the view’s source code indicating a problem, but I have found that to work only sometimes.

    I have seen the same problem with Visual Studio injecting an incorrect object after new.
