Q: Unable to write to a text file (Windows Universal) in c# using File.WriteAllText(); I'm trying to do a very VERY basic operation:
    public async Task WriteAsync(string path)
    {
        // Write to text file

        try
        {
            lines = "Hello, World";

            File.WriteAllText("Assets\\Write.txt", lines); 

        }
        catch (System.Exception e)
        {
            lines = e.Message;
        }
    }

I am getting the following exception:

{System.UnauthorizedAccessException: Access to the path '.......AppX\Assets' is denied.

I have Assets set to Everyone full control.  I have even attempted to pre-create the file in Windows and give THAT full control.  The error persists.
Ideas?
