Gets a value indicating whether the common language runtime (CLR) is shutting down.
Assembly: mscorlib (in mscorlib.dll)
When the CLR shuts down, it starts the finalizer thread on all objects that have a finalizer method. The property returns true only after the finalizer thread has been started. The CLR unloads the application domain at this time; therefore, the AppDomain.IsFinalizingForUnload method also returns true.
This property returns false if the finalizer thread has not been started.
By using this property, you can determine whether to access static variables in your finalization code. If the CLR is shutting down, you cannot reliably access any object that has a finalization method and that is referenced by a static field. This is because these objects may have already been finalized.
