To unblock those files there is a simple solution for multiple-recursive unblocking:

1\. Use 'Open in Terminal' item of the solution in 'Solution Explorer'.

2\. Enter the next commands in opened 'Developer PowerShell terminal':

Get-ChildItem \*.resx -Recurse | Unblock-File

3\. The command will complete without a confirmation.

4\. The projects in the solution now can be built.
