使用ASP .NET Core身份和EntityFrameworkCore注册新用户时出现InvalidOperationException

本文介绍了使用ASP .NET Core身份和EntityFrameworkCore注册新用户时出现InvalidOperationException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在遵循有关使用身份的文档并且正在尝试注册新用户（执行register操作），但是失败并出现以下错误：

I'm following the documentation for using Identity and am trying register a new user (executing the register action), but it fails with the following error:

InvalidOperationException：无法创建DbSet for'ApplicationUser'，因为此类型未包含在上下文模型中。

InvalidOperationException: Cannot create a DbSet for 'ApplicationUser' because this type is not included in the model for the context.

启动：

services.AddIdentity<ApplicationUser, IdentityRole>(options => { //password options options.Password.RequireDigit = false; // ... })

我正在使用标准的ApplicationUser：

I am using a standard ApplicationUser:

public class ApplicationUser : IdentityUser { }

在AccountController中注册操作：

Register action in AccountController:

public async Task<IActionResult> Register(RegisterViewModel viewModel) { if (ModelState.IsValid) { var user = new ApplicationUser { UserName = viewModel.UserName, Email = viewModel.Email }; var result = await _userManager.CreateAsync(user, viewModel.Password); //<-- Exception happens here if (result.Succeeded) { await _signInManager.SignInAsync(user, isPersistent: false); _logger.LogInformation(3, "User created a new account with password."); return RedirectToAction(nameof(HomeController.Index), "Home"); } string errorData = ""; foreach (var error in result.Errors) { errorData += error.Description + '\n'; } StoreErrorMessage("Failed to create the user!", errorData); } return View(viewModel); }

我已经尝试过以下操作：

I already tried the following:

• 将 DbSet< ApplicationUser> 添加到 AplicationContext
• 我确实通过 dotnet ef

• Adding DbSet<ApplicationUser> to AplicationContext
• I did create and apply a new migration via dotnet ef

推荐答案

我发现了问题。我的 ApplicationContext 是从 DbContext 继承的。我将其更改为 IdentityDbContext< ApplicationUser> ，它可以正常工作。

I found the problem. My ApplicationContext was inheriting from DbContext. I changed it to IdentityDbContext<ApplicationUser> and it works.
