Do you really need to process the text file? If not, then you can probably skip most of the content pipeline.
Sort of:
string filename = "Content/TextFiles/sometext.txt";
string path = Path.Combine(StorageContainer.TitleLocation, filename);
string lineOfText;
StreamReader sr = new StreamReader(path);
while ((lineOfText = sr.ReadLine()) != null)
{
}
