UiPath handles different dependency versions for multiple running processes that run at the same time by using the concept of isolation. This means that each running process uses its own required version of the dependency, without affecting or being affected by other processes. This ensures that the processes run smoothly and consistently, regardless of the dependency versions. The isolation is achieved by using the NuGet protocol, which allows the robot to download and store the dependencies in a local cache folder. The robot then loads the dependencies from the cache folder into separate application domains for each process, creating isolated environments for each process.
