For a couple years, I had been running Visual Studio 2015 on a Windows 10 Pro host within Parallels 15. On the old and new machine, I have had my Mac's home folder shared to the Windows Guest and mapped to the same drive letter, Z. All of my various projects/solutions worked on the old install. Recently, I got a new Macbook Pro and set up Parallels 15 on that new machine. Then I followed the transfer via https://www.parallels.com/blogs/transfer-existing-vm-to-new-mac/ On the new MBP, I open the VS2015 project/solution via the open dialog and step my way into the project folder. It loads fine, I can save when just editing and building. However, when trying to run the program (with or without debugging enabled) within VS2015 or even going to the location in a separate window, I get "Access is denied". Given the ecosystem in which I'm developing, I can't just change the project's OutputPath option to build to %TEMP%, etc. After this failure was noticed, I then upgraded to Parallels 17, thinking something changed within Parallels. The failure persists. Given that I migrated the guest, I'm at a loss for what would be different between the two configurations. Has anyone encountered this?
