I've happened to copy a small test code from PDF and while executing, I got the below error.
System.Windows.Markup.XamlParseException: Invalid character in the given encoding. Line 1, position 13.
The reason is due to Double quotes and it's not a technical bad code :-)
Be careful while copying the code from PDF. Mostly, it won't work due to this kind of simple issues.
