Windows XP Compatibility

PLEASE READ BEFORE POSTING AN ISSUE

This is a place for issues for MahApps itself. Questions are better asked in the Gitter room or at stackoverflow.

Seriously consider creating and linking to a test repo which takes absolutely minimal setup to illustrate how reproduce the problem.

My time is limited and .Zip files, code snippets and partial examples are often a time sink. GitHub also provides great communication and code review tools which can be utilised.

HOW TO POST A GOOD SAMPLE.

Follow these guidelines and I will most likely look at the issue sooner:

• Post a full GitHub repository. Not a zip file, half baked snippet etc. If GitHub is new to you consider it a great learning opportunity and chance to get involved.
• The repository should have just ONE step max for me to get running, and that is "Restore NuGet Packages". If there are any other missing dependencies, or uncompiling features I will most likely move on to another issue.
• I'm not trying to be awkward. I'm just busy and I'm helping a lot of people, not just you, so help me out and I will help you out.

What steps will reproduce this issue?

Windows XP isn't supported anymore neither by Microsoft nor by Mahapps.Metro.

private static bool _GetPhysicalCursorPos(out POINT lpPoint)
{
try
{
lpPoint.x = System.Windows.Forms.Cursor.Position.X;
lpPoint.y = System.Windows.Forms.Cursor.Position.Y;
return true;
}
catch
{
lpPoint = new POINT();
return false;
}

    }

Work for me
