GetSystemMetrics() returns different results for .NET 4.5 & .NET 4.0

Question

During a .NET 4.0 -> .NET 4.5 application migration process I\'ve discovered an extremely strange behavior. I\'ve been able to track this issue down to this short code snipp

Answer 1

According to Microsoft, this is by-design.

See here for full details:

• The SystemParameters.WindowResizeBorderThickness seems to return incorrect value - Microsoft Connect (no archived version available)
• Regression: ::GetSystemMetrics delivers different values - Microsoft Connect (archived)

Despite MS saying it's "by design", I still think it's a bug!
