Crash looking for a template file

[gordonwatts]

This is likely b.c. of the way we are doing our current directory (??).

LINTToTTreeLib Start: 13 : ExecuteQueuedQueriesForAScheme: Will part out 1 Uri's to run on remotebash.

And another crash where we weren't able to find the files describing the local tev cluster.

Searching for all occurrences of CurrentDirectory...

[gordonwatts]

What is interesting about the above crash is that the template file actually exists at that first location!

And the code couldn't be cleaner - or more immune to multi-threaded issues.

        private string TemplateDirectory(string templateName)
        {
            var assDir = new FileInfo(Assembly.GetCallingAssembly().Location);
            var assGuess = string.Format(@"{0}\Templates\{1}", assDir.DirectoryName, templateName);
            if (File.Exists(assGuess))
                return assGuess;

            var assGuess1 = string.Format(@"{0}\{1}", assDir.DirectoryName, templateName);
            if (File.Exists(assGuess1))
                return assGuess1;

            var guess = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\LINQToTTree\\Templates\\" + templateName;
            if (File.Exists(guess))
                return guess;

            throw new FileNotFoundException($"Unable to locatoin LINQToTTree template file '{templateName}' in any standard location (tried '{assGuess}' and '{assGuess1}' and '{guess}'.");
        }

Need to see this happen a little more often.
