Ok. When I start the application without Visual Studio it works. But not in Visual Studio. Why?

The Problem is the log in the destructor of PageProfileViewModel


~PageProfileViewModel() {                  Log.Debug("Destructor of VM " + UniqueIdentifier); }


       Task.Factory.StartNew(() => { Thread.Sleep(500);
                                     Log.Debug("Destructor of VM " + UniqueIdentifier);

In my Application it works not as expectedt. It deletes the old viewmodel not every time I create a new model. But I don't know why.
