Facebook/ Twitter with dotnetopenauth? [closed]

Solution 1:

At the time of me answering this question, DotNetOpenAuth has a public Community Tech Preview (CTP) which is available to download.

1. Download that source code. Should be a .7z file. You can use 7-Zip to unzip the code if you don't already have it (it's free).
2. Open up the samples source code solution in Visual Studio. I'm using VS2010 but I think there's also a VS2008 solution file.

3. Now, open up the web.config file for the OAuthClient project.

4. Next, edit the following settings :-

   <!-- Facebook sign-up: http://developers.facebook.com/setup/ -->

   <add key="facebookAppID" value="------"/>

   <add key="facebookAppSecret" value="------------"/>

You can get these values from your application on Facebook.

5. Debug/Run the OAuthClient Web Application. This will start an instance of Cassini/Visual Studio Developer Server and a web browser should open:

Voilà! you can now connect to Facebook to log in.

If you get errors, then you need to make sure that:

1. You've manually changed the Facebook app settings in your web.config file.
2. You've correctly setup your app settings in the Facebook developer website.
