Hello together,
we started to migrate our on premise crm into the cloud. the first thing I've done was to export our old system through a solution and tried to upload it in the cloud system.
There was a error "No publisher is found, assembly must be registered in isolation". I googled and found out that I needed to switch th isolation Mode of our plugins from 1 to 2 in the customization.xml of the solution. like described here:

It worked but I would like to understand why I needed to do this? Can anyone explain the rule behind?
