Remarks

Use this property with care, as its usability is limited. Its main use is for testing, and for non-library application code where just a single instance is sufficient.

The shared instance is not suitable for Windows Forms or similar environments, where a specific System.Threading.SynchronizationContext may be used with each form.

We also do not recommend using the shared instance for library code, due to conflicts that may arise if your library sets some instance parameters which may not be the same as what other libraries or the final application expects.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2012 R2, Windows Server 2016; .NET: Linux, macOS, Microsoft Windows
