I use DokanNet and Dokany to create a virtual disk.
A skin that does not do anything works on Win10, but on Win7 it completes within a minute after launch with an error. I checked only on two computers, so I can not guarantee what is connected with the version of the OS. Perhaps the problem is related to something else. The project properties have .net framework 4.5.2.
The standard RegistryFS example behaves the same way (if you change its dependency to the version of DokanNet.net4.0). The version under 4.6 is not compiled at all.
Just in case, here is my slightly modified and cleaned code:

How can I fix this problem?
