Prevent application being runned from network drive

I wonder if it was possible to prevent or at least detect if my application is being used from a network drive instead of a local folder/drive.

I wish to inform my user that he has to copy the sources and run them locally because of heavy performance pitfalls.

to prevent ArgumentException in case GetPathRoot returns \\Share\myshare

            DriveInfo driveInfo = null;

            try
            {
                driveInfo = new DriveInfo(Path.GetPathRoot(Assembly.GetEntryAssembly().Location));
            }
            catch (Exception)
            {
            }

            if (driveInfo == null || driveInfo.DriveType == DriveType.Network)
            {
                //not allowed
            }

Get the path to where your executable has been executed from, get the root, then find out if it is a network drive.

var root = Path.GetPathRoot(Assembly.GetEntryAssembly().Location)
var driveInfo = new DriveInfo(root));
if (driveInfo.DriveType == DriveType.Network) {
    // Alert that this will be slow.
}

Note that you should read the question I linked (How can I get the application's path in a .NET console application?), as there is potentially a bit more to it than the code above, depending on your exact scenario.
