Where I work we have a maped share folder where we put our compiled application to test it as a demo. Recently my computer updated to the latest Windows 10 update and we noticed that everyone that has Windows 10 throws an exception of invalid argument when trying to open a connection. Other coworkers that have Windows 7 can run it without problems. Furthermore if I copy those file to my Documents folder, it runs without problem.
It's something related with some new Windows permissions with shared folders? The shared folder is in a Linux server.
Exception message: Se ha proporcionado un argumento no válido (An invalid argument was supplied)

If the server hosting the share is using the SMBv1 protocol, this is normal (It's a security measure).
