Bad IL format. The format of the file is invalid. Can't publish project

@adriano.dias

Try to go to your nuget location and delete the packageswhich are showing error and reopne the project and check…this would download thos edependencies again

Also I see the activities are still on same versions did you happen to upgrade?

Also for publish try to go to home → setting and then toggle the workflow analyzer rules and validations off

Cheers
