Use Checking.Rooted()

This analyzer provides the following strings:

Context	String
Error List	Caller uses Path.IsPathRooted instead of Checking.Rooted()
Suggestion Box	Use Checking.Rooted() instead of Path.IsPathRooted
Description	Checking.Rooted() uses the filesystem driver to call Path.IsPathRooted.

Extended Description

This code analyzer detects the usage of Delete from the standard Directory class found in the System.IO namespace.

Using Path.IsPathRooted(), it doesn't use any driver to wrap this call, so it calls the built-in IsPathRooted() directly.

Alternatively, you can use Checking.Rooted(), which uses the filesystem driver for extensibility.
