The instance of entity type 'Item' cannot be tracked because another instance with the same key value for {'Id'} is already being tracked

Question

I am aware that such question has already been asked, but solution did not help me.

[Fact]
public async Task UpdateAsync()
{
    string newTitle = \"newTitle1\";         


        

Answer 1

In my case I hit this error when running SaveChanges twice inside of two IFs statements. I moved the SaveChanges outside of those two blocks of code. Just a side note in my service layer it is querying the data with AsNoTracking();

if (user.SendPaymentStatus)
{
    user.SendPaymentStatus = false;
    saveChanges = true;
    //_userService.SaveChanges(user, false);

    msg = GetPaymentHTML(user.MasterNodeName, user.Payee, DbMasterNode.LastPaidUtc);
    Framework.Email.SendEmail(email, "MasterNode Payment - " + user.MasterNodeName, msg);        
}

if (user.SendNodeStatus)
{
    user.SendNodeStatus = false;
    saveChanges = true;
    //_userService.SaveChanges(user, false);

    msg = GetStatusHTML(user.MasterNodeName, user.Payee, DbMasterNode.CurrentStatus, DbMasterNode.LastSeenUtc);
    Framework.Email.SendEmail(email, "MasterNode Down - " + user.MasterNodeName, msg);
}

if (saveChanges)
{
    user.SendPaymentStatus = false;
    _userService.SaveChanges(user, false);
}
