StaticExtension value cannot be resolved

I'm facing some issues with a WPF binding to a static property. In my application there is a class called Globals which contains a static property to ThisAddIn. This object allows me to access a User property which basically is what I want to use in my Binding. So, my XAML looks like this:

<TextBlock Text="{Binding Path=User.Name
                   , Source={x:Static Member=s:Globals.ThisAddIn}}" />

The namespace s is declared at the top by the following line:

xmlns:s="clr-namespace:ConsoleApplication16.Model"

I found a ton of different approaches of how to refer to the static Property in XAML, but none of them worked except for this one, which also seems the most logical for me. Some samples I found, did not use Path or Member at all.

After some testing I found the right way to do this, is using "x:Static Member" to define the class and the static property you want to use, while Path defines the correct Properties inside this object, just like a normal binding would do.

Although this solution compiles without any complains, a XAMLParseException pops up directly telling me that the StaticExtension value cannot be resolved to an enumeration, static field, or static property.

Ensure Globals.ThisAddIn is public.

You may also get this if you are using a resource file in which case you also need to ensure the access modifier is set to Public:

In output library project, you should ensure that the Resources.resx file's generator has been modified as PublicResXFileCodeGenerator instead of ResXFileGodeGenerator by default.

Replace following with...
