Invalid object name 'AspNetRoleClaims' exception when logging in - asp.net

Question

So I implemented Identity for my core project. I have successfully completed my Registration. So while trying to login using the _signInManager.PasswordSignInAsync I am getting the exception Invalid object name 'AspNetRoleClaims'.
I know this is because the AspNetRoleClaims table is not present in my database. But idont know the structure of this table nor do I know how to create it automatically like in mvc.
Can somebody enlighten me why this table is used. Or at least what is the expected structure.
public async Task<IActionResult> RegisterSubmit(Registermodel rm)
{
if (rm.role == "" || rm.role.Trim() == "-1")
{
return View();
}
else
{
var user = new ApplicationUser { UserName = rm.username, Email = rm.username, DeptName = rm.role };
var result = await _userManager.CreateAsync(user, rm.Password);
if (result.Succeeded)
{
_userManager.GenerateEmailConfirmationTokenAsync(user);
await _signInManager.SignInAsync(user, isPersistent: false);
var roleexists = await _roleManager.RoleExistsAsync(rm.role);
if (!roleexists)
{
var role = new IdentityRole();
role.Name = rm.role;
await _roleManager.CreateAsync(role);
}
await _userManager.AddToRoleAsync(user, rm.role);
user.Claims.Add(new IdentityUserClaim<string>
{
ClaimType = "ProductUploadRequest",
ClaimValue = "Allow"
});
}
return View("Login");
}
}
This is my login method.
public async Task<IActionResult> Login(LoginIdentityModel lim)
{
var result = await _signInManager.PasswordSignInAsync(lim.username, lim.password,false, lockoutOnFailure: false); //exception comes here
if (result.Succeeded)
{
var user = await _userManager.GetUserAsync(HttpContext.User);
UserProfileInfo userProfileInfo = new UserProfileInfo();
userProfileInfo.UserId = new Guid(user.Id);
userProfileInfo.FirstName = "test";
userProfileInfo.UserName = lim.username;
userProfileInfo.LastVisit = DateTime.Now;
string query2 = "select ud.UserId,dp.Id DeptId,dp.Name DeptName,rd.Id RoleId,rd.Name RoleName,ud.[ReadWrite] from UserInDepartment ud inner join Department dp on ud.DeptId=dp.Id inner join RolesInDepartment rd on dp.Id=rd.DeptId and ud.RoleId=rd.Id where ud.UserId='" + user.Id + "' and dp.IsEnable=1 and rd.IsEnable=1 and ud.IsEnable=1";
var userProfile = await _departMentalContext.UserProfiles.FromSql(query2).SingleOrDefaultAsync();
if (userProfile != null)
{
Dictionary<int, string> deptValues = new Dictionary<int, string>() { { userProfile.DeptId, userProfile.DeptName } };
userProfileInfo.Dept = deptValues;
Dictionary<int, string> roleValues = new Dictionary<int, string>() { { userProfile.RoleId, userProfile.RoleName } };
userProfileInfo.Role = roleValues;
userProfileInfo.ReadOrWrite = userProfile.ReadWrite;
HttpContext.Session.SetObject(UserProfileSessionName, userProfileInfo);
}
return View("/Home/DashBoard");
}
return View();
}

As you are using EF, you should be able to update your model database.
You can use CLI command (learn.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet).
Or if you are using Visual Studio, in the package manager console, you can execute those commands :
Add-Migration "init"
Update-Database
Commands allows you tu update table in your database. Also, it will create migrations files, which are a "picture" of your models. When the command Update-Database is executed, it loads the last migration file.
