Checking Dotnet version on server

I needed to check running dotnet version on a few servers to verify support for TLS 1.2
I used script below, which I though was easy to update and using hash-tables in an effective way.

	$version = (Get-ItemProperty "HKLM:SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full").Release
	write-output "Current version: $($version)"
	$versionTable = [ordered]@{
	".NET Framework 4.5" = 378389
	".NET Framework 4.5.1" = 378675
	".NET Framework 4.5.2" = 379893
	".NET Framework 4.6" = 393295
	".NET Framework 4.6.1" = 394254
	".NET Framework 4.6.2" = 394802
	".NET Framework 4.7" = 460798
	".NET Framework 4.7.1" = 461308
	".NET Framework 4.7.2" = 461808
	".NET Framework 4.8" = 528040
	}
	$versionTable.GetEnumerator() | ForEach-Object {
	if ($version -gt $_.value) {
	$currentVersion = $_.key
	}
	}
	write-output "Current version: $currentVersion"
