Fix a concurrency issue on EF Core project with an existing database

I have an existing client's database structure and have issue fixing resolving a concurrency exception when trying to insert/update/delete an entity. I suspect the it has to do with the computation at the database level which causes the entity to be modified before and after the operation. I would like to resolve this on the API level instead of modifying the database.

For the freelancers considering this, I would like to operate using TeamViewer and and allow partial control over the screen. We can set aside time to do a Skype call or Google Hangout as this is being resolved.
