Question

这够好吗？或者我是否也必须处置UserStore？如果我有任何建议，欢迎。我是ASP.NET身份的新手。

using (var applicationDbContext = new ApplicationDbContext())
{
    using (var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(applicationDbContext)))
    {

    }
}

我想这会更好：

using (var applicationDbContext = new ApplicationDbContext())
{
    using (var userStore = new UserStore<ApplicationUser>(applicationDbContext))
    {
        using (var userManager = new UserManager<ApplicationUser>(userStore))
        {

        }
    }
}

编辑：我很高兴我问过这个问题，虽然我可能已经回答了我的初步问题。感谢Glenn Ferrie，将检查ASP.NET依赖注入。

这是使用VS 2015 RC创建的新ASP.NET MVC（.NET 4.6）的一些代码片段。首先是Startup类：

public partial class Startup
{
    // For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864
    public void ConfigureAuth(IAppBuilder app)
    {
        // Configure the db context, user manager and signin manager to use a single instance per request
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
        app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
// rest of implementation ommitted for brevity.

然后，您将在Controller类中访问它：

public class AccountController : Controller
{
    private ApplicationSignInManager _signInManager;
    private ApplicationUserManager _userManager;

    public AccountController()
    {
    }

    // NOTE: ASP.NET will use this contructor and inject the instances
    // of SignInManager and UserManager from the OWIN container
    public AccountController(ApplicationUserManager userManager, ApplicationSignInManager signInManager )
    {
        UserManager = userManager;
        SignInManager = signInManager;
    }
    // there are implementations for the public properties
    // 'UserManager' and 'SignInManager' in the boiler plate code
    //  not shown here

快乐的编码！

在AccountController之外放置UserManager和UserStore？
