C# 在ASP.NET MVC应用程序中使用UserManager的种子方法期间未创建任何用户
当C# 在ASP.NET MVC应用程序中使用UserManager的种子方法期间未创建任何用户,c#,.net,entity-framework,asp.net-mvc-5.1,C#,.net,Entity Framework,Asp.net Mvc 5.1,当Seed方法运行时，记录/对象被添加到我的数据库中 在我尝试将用户添加到我的应用程序之前（在Seedmethod的底部），每个对象都会按其应该的方式添加。没有人被添加。此外，在底部还有大量抛出的SQL异常。即使Seed方法为空，也会抛出它们 如何将用户添加到实体框架管理的数据库？我根据Scott Allen的教程创建了代码 protected override void Seed(WebApplication2.Models.ApplicationDbContext context) {
SeedSeedSQLSeed protected override void Seed(WebApplication2.Models.ApplicationDbContext context) {
System.Diagnostics.Debug.WriteLine("Seed started");//IT WORKS

您必须从上下文中获取当前管理器：
var manager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
使用此管理器实例，您应该能够正确创建用户。是否在调试中运行？用户的状态是什么。有吗？除非显式调用数据库初始化，否则种子方法不会在运行时运行。（或者，在设计时，您可以在nuget命令行中使用db migrations来对要执行的seed方法进行case处理）。如果您担心异常，您应该在
