ObservableObject in WPF

[malsabi]

I'm using MVVM Toolkit in a WPF Project, I have a View-Model 'DashboardViewModel' that inherits ObservableObject. The issue is that when I set the Data-Context in the xaml view I'm getting these exceptions:

• If I removed the ObservableObject from the View-Model ('DashboardViewModel') it will work fine as expected.

Also here is how I'm setting the Data-Context in the xaml file:

NOTES::

1. This approach was done in UWP and I had no errors/exceptions.
2. I can fix the issue by setting the View-Model in the Code-Behind as the following:
   
   Also there won't be any errors.
3. I can fix the issue by assigning a value to the d:DataContext that sets the design-time Data Context as the following:
   
4. I can fix the issue by using View-Model-Locator technique.

Yet I prefer to use the first simple solution, Is there any work around for it ? I'm confused why it works in UWP and not in WPF, I guess maybe because the library is focusing more on the UWP.

Why do you need the x:Name attached property on there? From your problem description it seems that's the only problem?
