This is still happening in 11.0.1 (31277).
I don't have to run/debug for it to happen - I have one particular visual studio solution with 100+ Projects in it, and at some point while loading all those projects it stops me from browsing shares within \\psf or \\mac.
The solution appears to load OK but then trying to open an individual file results in the not found error message: "The item <filename> does not exist in the project directory. It may have been moved, renamed or deleted".
If I then go to Explorer.exe and Z: (which for me maps to \\psf\Home) it doesn't show any files or folders there. Instead the window shows the message "This folder is empty." like when you create a new folder and immediately go into it.
If I type \\psf in the address bar and hit enter it displays the shares at \\psf. Same for if I go to \\mac. I have one share 'Home'. If I double-click Home however to view the Home directory it shows the 'This folder is empty' message.
If I try to go directly to \\psf\Home\Documents (or any other directory that I know exists) it takes me to the directory but gives the message "This folder is empty.". It knows the directory is there, as if I go to a directory I know that doesn't exist (i.e. \\psf\Home\NotThereAtAll) it immediately gives the alert 'Windows cannot access <directory name>'.
The moment I close Visual Studio again, all the files are listed and accessible in Windows Explorer.
It looks to me like Visual Studio is doing something where with too many files read/accessed/opened at once the share reaches a limit where it can't be browsed any longer.
If I do a 'net use' at any point through it shows just one entry:
Z: \\mac\home Parallels Shared Folders
