'No database provider has been configured for this DbContext' on SignInManager.PasswordSignInAsync

.Net Core 1.0.0 - SDK Preview 2 (x64)

.Net Core 1.0.0 - VS "15" Preview 2 (x64)

.Net Core 1.0.0 - Runtime (x64)

So, we updated an RC1 app to the latest versions above. After many hours of switching references, it's running. However, when logging in (AccountController/Login), I am getting an error at:

public class AccountController : BaseController
{
public UserManager<ApplicationUser> UserManager { get; private set; }
public SignInManager<ApplicationUser> SignInManager { get; private set; }
private readonly IEmailSender EmailSender;


public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager, IEmailSender emailSender)
{
UserManager = userManager;
SignInManager = signInManager;
EmailSender = emailSender;
}


// GET: /Account/Login
[HttpGet]
[AllowAnonymous]
public IActionResult Login(string returnUrl = null)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}


//
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(ViewModels.Account.LoginViewModel model, string returnUrl = null)
{
if (ModelState.IsValid)
{
// Errs this next line
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, false); // <-- ERRS HERE '.PasswordSignInAsync'
if (result.Succeeded)
return RedirectToLocal(returnUrl);


ModelState.AddModelError("", "Invalid email or password.");
return View(model);
}


// If we got this far, something failed, redisplay form
return View(model);
}
            

It blows up with the following error message:

InvalidOperationException: No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions object in its constructor and passes it to the base constructor for DbContext.

Here is the Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));


// Add EF services to the services container.
services.AddEntityFrameworkSqlServer()
.AddDbContext<LogManagerContext>(options =>
options.UseSqlServer(Configuration["Data:DefaultConnection:Connectionstring"]));


services.AddSingleton(c => Configuration);


// Add Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<LogManagerContext>()
.AddDefaultTokenProviders();
            

        

// Add MVC services to the services container.
services.AddMvc();


services.AddTransient<IHttpContextAccessor, HttpContextAccessor>();


//Add all SignalR related services to IoC. - Signal R not ready yet - Chad
//services.AddSignalR();


//Add InMemoryCache
services.AddMemoryCache();


services.AddSession(options =>
{
options.IdleTimeout = System.TimeSpan.FromHours(1);
options.CookieName = ".LogManager";
});


// Uncomment the following line to add Web API servcies which makes it easier to port Web API 2 controllers.
// You need to add Microsoft.AspNet.Mvc.WebApiCompatShim package to project.json
// services.AddWebApiConventions();
// Register application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
        

}


// Configure is called after ConfigureServices is called.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseSession();


// Configure the HTTP request pipeline.
// Add the console logger.
//loggerFactory.MinimumLevel = LogLevel.Information; - moved to appsettings.json -chad
loggerFactory.AddConsole();
loggerFactory.AddDebug();


loggerFactory.AddNLog();


// Add the following to the request pipeline only in development environment.
if (env.IsDevelopment())
{
app.UseBrowserLink();
app.UseDeveloperExceptionPage();
//app.UseDatabaseErrorPage(DatabaseErrorPageOptions.ShowAll);
}
else
{
// Add Error handling middleware which catches all application specific errors and
// sends the request to the following path or controller action.
app.UseExceptionHandler("/Home/Error");
}


env.ConfigureNLog("NLog.config");


// Add static files to the request pipeline.
app.UseStaticFiles();


// Add cookie-based authentication to the request pipeline.
app.UseIdentity();


//SignalR
//app.UseSignalR();


// Add MVC to the request pipeline.
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "Home", action = "Index" }
);


// Uncomment the following line to add a route for porting Web API 2 controllers.
// routes.MapWebApiRoute("DefaultApi", "api/{controller}/{id?}");
});
}

And here's the Context:

public class ApplicationUser : IdentityUser
{
// Add Custom Profile Fields
public string Name { get; set; }
}


public class LogManagerContext : IdentityDbContext<ApplicationUser>
{
public DbSet<LogEvent> LogEvents { get; set; }
public DbSet<Client> Clients { get; set; }
public DbSet<LogEventsHistory> LogEventsHistory { get; set; }
public DbSet<LogEventsLineHistory> LogEventsLineHistory { get; set; }
public DbSet<LogRallyHistory> LogRallyHistory { get; set; }
public DbSet<Flag> Flags { get; set; }
protected override void OnModelCreating(ModelBuilder builder)
{


builder.Entity<LogEvent>().HasKey(x => x.LogId);
builder.Entity<LogEvent>().ToTable("LogEvents");
builder.Entity<Client>().HasKey(x => x.ClientId);
builder.Entity<Client>().ToTable("Clients");
builder.Entity<LogEventsHistory>().HasKey(x => x.HistoryId);
builder.Entity<Flag>().HasKey(x => x.FlagId);
builder.Entity<Flag>().ToTable("Flags");
builder.Entity<LogRallyHistory>().HasKey(x => x.HistoryId);
builder.Entity<LogEventsLineHistory>().HasKey(x => x.LineHistoryId);


base.OnModelCreating(builder);
}
