Entity core framework fix at 2026.100?

I’m just saying they’re introducing it at a place where they said they’d break stuff.

Ah, I see now. Still, compared to the Linux change the move from EF6 to EFCore was lacking since it caught so many of us off guard.

I don’t disagree with anyone, I wish there was more of a heads up on this. Thank goodness @hkeric.wci and @JeffLeBert told us about it with as much notice as they possibly could.

I wonder if the EF Core stuff caught them just as off-guard as us… This seems to be much more significant than the Linux stuff for most environments.

As much crazy stuff as I do, I haven’t had a single linux issue.

Linux probelms were mostly with file names, paths, case-sensitivity.

EF Core and MARS have more extensive use everywhere with DB.

So these were first brought up in 2025.2 Upgrade, actually Conversions even had a WARNING / Link to @JeffLeBert 's Gist when you compile the BPMs it told you about potential EF Core issues back then we went and fixed a bunch. It was in the conversion log burried

But yes I’m not sure it was “announced” per say

I suspect so. Even between the different Microsoft .Net Core versions, the compatibility and feature issues have been a mess. There were ‘security’ changes happening all over the place. We had multiple occasions of different behavior/issues in different environments with the same Kinetic version but just with different early .Net Core versions. It caused a lot of frustration and pain for us.

That .Net Core 10 will be the only supported version by Microsoft from November 10 wouldn’t have been leaving other options open either. Particularly with AI finding so many new vulnerabilities and issues with pretty every major framework at the moment. With the shrinking support timelines, and it seems more companies mandating to be using currently fully supported software stacks for security reasons, it is looking like there could be quite a few painful circumstances that there is not even much that companies as large as Epicor can do about it.

EF6 is still supported and works on linux fine. They could have pushed this down the road a bit if they wanted instead of so many major changes at once.
