Peripheral object creation issue

When you get the error
System.IO.IOException: The process cannot access the file 'C:\TwinCAT\3.1\Components\Plc\Managed Libraries\cache' because it is being used by another process.
just click OK and export again until export finishes without this error.
It is a kind of timing error when the export installs libraries and TwinCAT is updating the library cache.
If you are using NexeedEcStaubliCS9uniValPlc, updating your project to TwinCAT 3.1.4022.32 will solve the problem (because with TC <4022.32 the library is installed during every export although it exists already).
