ASP.NET MVC捆绑包中的500内部服务器错误

Question

I do bundle my JavaScript files with ASP.NET MVC Bundling. When I inspect and check Network Tab in my browser, I see 500 Internal Server Error when my bundle wants to load. response:

A second operation started on this context before a previous asynchronous operation completed. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context. Any instance members are not guaranteed to be thread safe.

I understand that this error happened in my GenerateIdentityAsync method. I use ASP.NET Identity 2.0 so I use it from OnValidateIdentity in Owin Startup class:

ApplicationManager.cs

public class ApplicationManager : IApplicationManager
{
   // more code
   public Func<CookieValidateIdentityContext, Task> OnValidateIdentity()
   {
      return SecurityStampValidator.OnValidateIdentity<AppUserManager, User, Guid>
      (TimeSpan.FromSeconds(0), GenerateIdentityAsync, identity => Guid.Parse(identity.GetUserId()));
   }

    public async Task<ClaimsIdentity> GenerateIdentityAsync(AppUserManager manager, User user)
    {
      var identity =
        await  CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie).ConfigureAwait(true);
     identity.AddEnumClaim("lastSeenMode", user.LastSeenMode);
     identity.AddClaim(new Claim("emailAddress", user.Email));
     identity.AddClaim(new Claim("displayName", user.DisplayName));
     identity.AddClaim(new Claim("lastseen", user.LastSeen.ToString()));
     return identity;
   }
}

startup.cs

  app.UseCookieAuthentication(new CookieAuthenticationOptions()
  {
        Provider = new CookieAuthenticationProvider()
        {
            OnValidateIdentity = SmObjectFactory.Container.GetInstance<IAppUserManager>().OnValidateIdentity(),
        }
  });

also i test ConfigureAwait(true) and ConfigureAwait(false) and without ConfigureAwait but donot solved this issue.

Update :
Also, when I use EF Profiler , it says Using A Single Object Context In Multiple Threads Is Likely A Bug.

this alert exist just for same table:

[Admin].[UserClaims]
[Admin].[UserLogin]
[Admin].[Roles]
[Admin].[UserRoles]
[Admin].[Users]

How can I solve this issue?

I not use StructureMap by myself, but i found that for MVC the best way to use StructureMap with MVC is to install StructureMap.MVC5.Update package (that's for latest StructureMap version).
Check small intro how to use it. Or this article.

Move all your existing registration code to DefaultRegistry.cs installed by package. And now don't use HybridHttpOrThreadLocalScoped() for services registration.
