How to GET data from an URL and save it into a file in binary in C#.NET without the encoding mess?

Question

In C#.NET, I want to fetch data from an URL and save it to a file in binary.

Using HttpWebRequest/Streamreader to read into a string and saving using StreamWriter works

Minimalist answer:

using (WebClient client = new WebClient()) {
    client.DownloadFile(url, filePath);
}

Or in PowerShell (suggested in an anonymous edit):

[System.Net.WebClient]::WebClient
$client = New-Object System.Net.WebClient
$client.DownloadFile($URL, $Filename)
