Colleagues,

In XAML I’m trying to declare XmlDataProvider objects to bind controls to XML files.
Code:
<XmlDataProvider x:Key="SerialPortOptions" Source="Settings/SerialPortOptions.xml" XPath="//Options" /> <!—- This one works.  No complaints. -->
<XmlDataProvider x:Key="SerialPortSetting" Source="Settings/SerialPortSettings.xml" XPath="//SerialPorts" /> <!—- But this one gives an error. -->
The second instance generates an error:
The file Settings/SerialPortSettings.xml is not part of the project or its 'Build Action' property is not set to 'Resource'.
The SerialPortSettings.xml file is added to the project and the Build Action is set to ‘Resource’. If I rename the file to SerialPortSettingses.xml, the error disappears. What’s special or unusual about the original file name SerialPortSettings.xml?

Cheers,
- Nick
