I have to update textboxes text with data that is returned from Sharepoint. The data is shared across many viewmodels so I store it into a static dictionary. The problem occurs when the thread accessing sharepoint returns, the properties are not notified of change/ changed.

public SpModel 
{
	Static dictionary<string,string> exposedDictOfValues;
	List resultsFromSharepointXml
	
	GetSharepointXmlAsync{
		...
		resultsFromSharepointXml = _list.getItems(query);
		executeQueryAsync(success,fail);
		...
	}
	
	success()
	{
		exposedDictOfValues = Convert(resultsFromSharepointXml);
	}
	
	fail(){}
}

public ViewModel : INotifyPropertyChanged
{
	public string MyProp
	{
		get
		{
			return SpModel.exposedDictOfValues["myProp"]
		}
		set
		{
			if(SpModel.exposedDictOfValues["myProp"] != value) 
			{
				SpModel.exposedDictOfValues["myProp"] = value;
				NotifyPropChange("MyProp");
			}
			
		}
	}
}

public View
{
	view(){
		DataContext = ViewModel;
	}
}

view.xaml
<textbox Text={Binding MyProp,Mode=TwoWay} />

Figured it out. Passed down the UI Dispatcher and executed the method using it and the viewmodel as a singleton.
