Sounds like an external process (AV?) is locking it, but can't you avoid the problem in the first place?

private static bool modifyFile(FileInfo file, string extractedMethod, string modifiedMethod)
{
    try
    {
        string contents = File.ReadAllText(file.FullName);
        Console.WriteLine("input : {0}", contents);
        contents = contents.Replace(extractedMethod, modifiedMethod);
        Console.WriteLine("replaced String {0}", contents);
        File.WriteAllText(file.FullName, contents);
        return true;
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
        return false;
    }
}
