For the view model solution, it seems the POST action method is missing. I created it as below, and tested. The modified data was saved. Now I can move to the next.

//

// POST: /StoreManager/EditVM/115

[HttpPost]

public ActionResult EditVM(Album album)

{

if (ModelState.IsValid)

{

db.Entry(album).State = EntityState.Modified;

db.SaveChanges();

return RedirectToAction("Index");

}

AlbumSelectListViewModel aslvm

= new AlbumSelectListViewModel(album, db.Artists, db.Genres);

return View(aslvm);

}

Unable to retrieve metadata for 'MvcMusicStore.Models.Album'. Using the same DbCompiledModel to create contexts against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used.
