My answer isn't as good as Noldorin's, but I'll leave it so people can see the alternative method. This isn't as good for simple splits, but it is more flexible if you need to do more complex parsing.

using System.Text.RegularExpressions;

string data = "asdf aA asdfget aa uoiu AA";
string aaRegex = "(.+?)[aA]{2}";

MatchCollection mc = Regex.Matches(data, aaRegex);

foreach(Match m in mc)
{
    Console.WriteLine(m.Value);
}
