Answer 1

Here's a basic way of doing it that I came up with using Regex

public static string CamelCaseToSentence(this string value)
{
    var sb = new StringBuilder();
    var firstWord = true;

    foreach (var match in Regex.Matches(value, "([A-Z][a-z]+)|[0-9]+"))
    {
        if (firstWord)
        {
            sb.Append(match.ToString());
            firstWord = false;
        }
        else
        {
            sb.Append(" ");
            sb.Append(match.ToString().ToLower());
        }
    }

    return sb.ToString();
}

It will also split off numbers which I didn't specify but would be useful.
