New Post: Authentication with Embedded Credentials

The documentation suggests one can manually set all the credentials like this:

TwitterCredentials.SetCredentials(
    AccessToken,
    AccessTokenSecret,
    ConsumerKey,
    ConsumerSecret);

This is perfect for me because I am only trying to do things on behalf of my own Twitter account and therefore I can easily find the Access Token and Secret and embed them in my application. However, setting them in this fashion never seems to work. Is there any way to sign in on behalf of my own account without using a callback or CAPTCHA (i.e. without needing user interaction)? I'm just trying to run a Windows Service on behalf of my own account.
