Question

我用visualstudio 2015 ctp创建了一个asp.net 5项目。如你所知，它准备身份系统。在accountcontroller上有一个名为Register的方法，当我测试它时，它可以正常工作但是当我向它添加以下代码时：

在添加新代码之前

await SignInManager.SignInAsync(user, isPersistent: false);
return RedirectToAction("Index", "Home");

添加新代码后

：

await SignInManager.SignInAsync(user, isPersistent: false);

// new lines for adding the new Role to the database
ApplicationDbContext adbc = new ApplicationDbContext();
var roleStore = new RoleStore<IdentityRole>(adbc);
var roleManager = new RoleManager<IdentityRole>(roleStore);
await roleManager.CreateAsync(new IdentityRole { Name = "Administrator" });
// end of the new lines

return RedirectToAction("Index", "Home");

但添加此新行后会返回以下错误：

InvalidOperationException：已配置关系存储，但未指定要使用的DbConnection或连接字符串。

似乎我们必须在启动时为角色管理器初始化dbcontext。启动代码已经是：

public void ConfigureServices(IServiceCollection services)
{
    // Add EF services to the services container.
    services.AddEntityFramework(Configuration)
        .AddSqlServer()
        .AddDbContext<ApplicationDbContext>();

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

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

    // 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();

}

// Configure is called after ConfigureServices is called.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerfactory)
{
    // Configure the HTTP request pipeline.
    // Add the console logger.
    loggerfactory.AddConsole();

    // Add the following to the request pipeline only in development environment.
    if (string.Equals(env.EnvironmentName, "Development", StringComparison.OrdinalIgnoreCase))
    {
        app.UseBrowserLink();
        app.UseErrorPage(ErrorPageOptions.ShowAll);
        app.UseDatabaseErrorPage(DatabaseErrorPageOptions.ShowAll);
    }
    else
    {
        // Add Error handling middleware which catches all application specific errors and
        // send the request to the following path or controller action.
        app.UseErrorHandler("/Home/Error");
    }

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

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

    // 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?}");
    });
}

有什么想法吗？

Asp.Net 5 IdentityRole CreateAsync不起作用
