What seemed like it should have been a common example on MSDN was not \u2026, and after a bit of searching and reading, I believe the above code represents at least a common and safe way of loading data. <\/div>\n<\/div>\n

\"image\"<\/a><\/p>\n
And the file\u2019s Build Action<\/strong> is set to Content:<\/strong><\/p>\n
\"image\"<\/a><\/p>\n
Change the value passed to the Uri<\/strong> constructor and \u2026 the file will be loaded successfully.
