Im using a backgroundworker in my ASP.NET application that throws this exception: '[login to view URL]: A second operation started on this context before a previous operation completed. This is usually caused by different threads using the same instance of DbContext. For more information on how to avoid threading issues with DbContext' I'd like you to look at my code and solve this problem.

Hi, this error occurs because there is a problem executing code asynchronously, a common mistake when a webapp is scaling. I have solved these issues a lot of times but this might take atleast a day to fix your entire architecture to prevent it from happening again. While a single issue might be solved in a hour, the underlaying problem will still stay, so you need a bigger budget. If you look for quality then let's chat.

Hi How are you ? Is your _context declared static maybe? Are you calling method multiple times in the same request from somewhere else ? Ideally, you would use dependency injection for your DbContext. Already caught a lot for this error, because I work with dbcontext every day. Thanks.
