I am using Microsoft Visual Studio Community 2022 (64-bit) v17.14.16. I have followed your code but I am getting error in OnValidSubmitAsync when the function
private async Task OnValidSubmitAsync() { var firstName = user.FirstName; var lastName = user.LastName; if (Input.FirstName != firstName) { user.FirstName = Input.FirstName; await UserManager.UpdateAsync(user); } if (Input.LastName != lastName) { user.LastName = Input.LastName; await UserManager.UpdateAsync(user); } if (Input.ProfilePicture != null && Input.ProfilePicture.Length > 0) { user.ProfilePicture = Input.ProfilePicture; await UserManager.UpdateAsync(user); } if (Input.PhoneNumber != phoneNumber) { var setPhoneResult = await UserManager.SetPhoneNumberAsync(user, Input.PhoneNumber); if (!setPhoneResult.Succeeded) { RedirectManager.RedirectToCurrentPageWithStatus("Error: Failed to set phone number.", HttpContext); } } await SignInManager.RefreshSignInAsync(user); RedirectManager.RedirectToCurrentPageWithStatus("Your profile has been updated", HttpContext);}This error in the console:
