Here's a super quick little powershell snippet to strip regions out of all C# files in a directory tree. Useful for legacy code where people hide long blocks in regions rather than encapsulate it into smaller methods/objects.

dir -recurse -filter *.cs $src | foreach ($_) {
    $file = $_.fullname
    echo $file
    (get-content $file) | where {$_ -notmatch "^.*\#(end)?region.*$" } | out-file $file

Run this in your solution folder and support the movement against C# regions!
