@orlangur But a LOT of people do their development work on windows.

This change is not deliberate; it's an error introduced by Magento and their Vagrant-only development ritual.

magento\framework\View\Element\Template\File\Validator.php

    /**
     * Checks whether path related to the directory
     *
     * @param string $path
     * @param string|array $directories
     * @return bool
     */
    protected function isPathInDirectories($path, $directories)
    {
        if (!is_array($directories)) {
            $directories = (array)$directories;
        }
        $realPath = $this->fileDriver->getRealPath($path);
        foreach ($directories as $directory) {
            if (0 === strpos($realPath, $directory)) {
                return true;
            }
        }
        return false;
    }

$realPath was added in 2.3.0 and does not return the expected slashes.

$realPath = 'C:\Server\Apache24\htdocs\magento-2.3\vendor\magento\module-theme\view\frontend\templates\page\js\require_js.phtml'
$directory = 'C:/Server/Apache24/htdocs/magento-2.3/vendor/magento/module-theme'

strpos cannot return 0 on Windows.

@00110000,

a LOT of people do their development work on windows

It means nothing but they do their development wrong and at their own risk. There are a lot of options nowadays, like Docker, Vagrant or other virtualization technics available for Windows.

Windows is not supported, was never supported and always led to some bugs. Patches for Windows compatibility are not acceptable in this repo.

The only thing Magento lacks here is proper environment check, similar to an unsupported PHP version check. Hope it will change soon.

@00110000 i'm know a guy, who works with WSL a long time, and have no issue with it. so this may be a good solution

[tuongnv-ub]

@engcom-backlog-nazar , @00110000 . Thanks for sharing. I'm Setup and working with WSL as well.

@engcom-backlog-nazar would be great to have such setup described somewhere in DevDocs for Windows guys. It would be much more friendly than just pointing to system requirements: https://github.com/magento/magento2/blob/2.3-develop/app/bootstrap.php#L17
