Running the following command generates the following error

dotnet ef dbcontext scaffold "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={Removed};" EntityFrameworkCore.Jet

It sounds like you are using alpha 1 from nuget.

That was built against the preview 7 of upstream EF Core. While for the most part it should work, there was a major change between the upstream RC1 and RC2 related to the History Repository (the part that deals with the __EFMigrationsHistory table).

This is the part that it is looking for and not finding.

I do have that fixed in the current daily builds (see #265) so the next release to nuget will have it.

In the meantime, you can try follow the instructions and link to a daily build.

I will keep this open for now until there is a version available in nuget that has the above fix in it

@roughiain There is a beta release that should now be on nuget that is compatible

[roughiain]

@ChrisJollyAU will test and give feedback

Works! thank you.
