Gets or sets a value indicating whether to catch calls on the wrong thread that access a control's Handle property when an application is being debugged.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When a thread other than the creating thread of a control tries to access one of that control's methods or properties, it often leads to unpredictable results. A common invalid thread activity is a call on the wrong thread that accesses the control's Handle property. Set to true to find and diagnose this thread activity more easily while debugging.
