I am having a trouble fixing this error, I am trying to edit an information of a specific user but when I click the "Edit" button I am getting this error in my web browser saying:
InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'SanMarinoClassicWebsite.Auth.ApplicationUser', but this ViewDataDictionary instance requires a model item of type 'SanMarinoClassicWebsite.ViewModels.EditUserViewModel'.
what could I've done wrong?
Here is the action of my Admin Controller for editing the information
[Authorize(Roles ="Administrator")]
public class AdminController : Controller
{
private readonly UserManager<ApplicationUser> _userManager;
private readonly RoleManager<IdentityRole> _roleManager;
public AdminController(UserManager<ApplicationUser> userManager,
RoleManager<IdentityRole> roleManager)
{
_userManager = userManager;
_roleManager = roleManager;
}
public IActionResult Index()
{
return View();
}
public IActionResult UserManagement()
{
var users = _userManager.Users;
return View(users);
}
public IActionResult AddUser()
{
return View();
}
[HttpPost]

addUserViewModel)
{
if (!ModelState.IsValid) return View(addUserViewModel);
var user = new ApplicationUser()

City = addUserViewModel.City,
Birthdate = addUserViewModel.Birthdate,
Country = addUserViewModel.Country
};
IdentityResult result = await _userManager.CreateAsync(user,
addUserViewModel.Password);
if (result.Succeeded)
{
return RedirectToAction("UserManagement", _userManager.Users);
}
foreach (IdentityError error in result.Errors)
{
ModelState.AddModelError("", error.Description);
}
return View(addUserViewModel);

wrong.");
