[FrancisGauthier]

added fluent WithIdentityInsert() with EFSave method in order to deactivate and reactivate Identity insert in an sql database.

added a test project with a test container to run an actual sql server for testing purposes.

Requires docker installed

Need to add test executions in the pipeline/workflow. This can be added in another PR or within this one.

Hi, its been a while the pr is open. I rebased the code and reverted some code i accidentally pushed in my fork.

Let me know if i can help with anything else. I think this would be a nice addition to this library. We do use that library for a custom ETL in a project and keeping the identity ids is really helpfull. Otherwise we have to disable and reenable identity columns before and after ETL processes

Thanks,

Hi @FrancisGauthier thanks for the PR. I will check your PR closely. As this part of the code you changed is very sensitive, I wanted to give me more time to check... but I don't have much of it lol. Can you describe me in more details the problem you want to address with this PR?
