Hi

We are using latest version of asp.net MVC Core and jQuery.

In one of our app service we have multiple item deletion which works ike this:

public async Task FirstLevel(List<int> Ids) { foreach(var i in Ids) { SecondLevel(id); } }

private async Task SecondLevel(int id) { //Fetch data from repository //Delete obj MethodWithThread(obj.extId) }

private async Task MethodWithThread(string extId) { Task.Factory.StartNew(() => { call external apis }; }

Here in MethodWithThread we were getting A second operation started on this context before a previous operation completed so tried to used using (var uow = UnitOfWorkManager.Begin(TransactionScopeOption.RequiresNew)).

But after using that in our second level methid still randomlt getting A second operation started on this context before a previous operation completed and also 2nd record in loops randomly not gets deleted.

Is there any other way to get data in method with thread?

    (I hardly understand your problem. (Sory if I get something unrelated))

    Could it be about forgetten await?

    await MethodWithThread(obj.extId);
