}
In this code all are correct but i need await _db.SaveChangesAsync() instead of _db.SaveChangesAsync(). If i put await operator in front of _db.SaveChangesAsync(), it shows me an error like await operator can only be used within an async lamda expression.
Now where should i use async keyword to resolved this error.
