Implements: IPlatformModeDetector

Remarks¶

This class is typically used to determine if code is executing within a designer environment, such as Visual Studio or Blend, to enable or disable design-time specific logic. The detection result is memoized, so a process that starts outside a designer never re-runs the probes. Thread safety is not guaranteed.

Which probes are compiled depends on the target framework. Splat.Drawing sets UseWPF and UseWindowsForms for the .NET Framework and Windows-specific targets, so those builds call the WPF designer API directly instead of reflecting over it. The target-framework-neutral builds keep a reflective probe, because a Windows desktop application resolves to them when its own platform version predates the Windows-specific targets. The Android and Apple targets cannot host a XAML designer at all and compile no designer probe.
