[LINQPad 5] Cannot run two lprun instances concurrently with shared MyExtensions in portable install

nescafe · March 2020

I've set up a folder with LINQPad.exe and a Plugins folder. I run two scripts, one permanently (directory watcher) and one periodically (sync every 30 minutes).

In 5.40.0.0, this works fine. However, in 5.41.0.0, the scheduled task fails if the watcher is running:

Perhaps CheckForStaleExtensions can be made a bit more error forgiving?
