title: Reading file content changes in .NET
body: <p>In Linux, a lot of IPC is done by appending to a file in 1 process and reading the new content from another process.</p>
  
  <p>I want to do the above in Windows/.NET (Too messy to use normal IPC such as pipes). I'm appending to a file from a Python process, and I want to read the changes and ONLY the changes each time FileSystemWatcher reports an event. I do not want to read the entire file content into memory each time I'm looking for changes (the file will be huge)</p>
  
  <p>Each append operation appends a row of data that starts with a unique incrementing counter (timestamp+key) and ends with a newline.</p>
