我有一个摇摇晃晃的asp.net core 2.1应用程序，无论何时尝试登录或注册新用户，我都会不断收到以下错误消息：“ InvalidOperationException：无法为'ApplicationUser'创建DbSet，因为此类型不包括在内上下文模型。”
出现_signInManager.PasswordSignInAsync（）时，它就会爆发。
我陷入困境，无法理解需要进行哪些更改。尝试我们链接，但没有解决。
这是我的login.cs
public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = "/RealTimeChart/Index")
{
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
//ApplicationUser signedUser = await _userManager.FindByEmailAsync(model.Email);
//var result = await _signInManager.PasswordSignInAsync(signedUser.UserName, model.Password, model.RememberMe, false);
var signedUser = await _userManager.FindByEmailAsync(model.Email);
var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: true);
if (result.Succeeded)
{
_logger.LogInformation("User logged in.");
return RedirectToLocal(returnUrl);
}
if (result.IsLockedOut)
{
_logger.LogWarning("User account locked out.");
return RedirectToAction(nameof(Lockout));
}
else
{
ModelState.AddModelError(string.Empty, "Invalid login attempt.");
return View(model);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
