Hi experts,

I am writing my first Facebook application using C# SDK.

I am getting required access token from Javascript and then fetching facebook data from using C# server side code.

Above code is working perfectly fine for admin of the facebook application (the user who has created the FB application), but any other user is not getting access token using same code.

I hope my question is clear.

JS code to get access token should work for any user.
Any kind of help is appropriated.

Thanks a lot in advance.

i think you are missing the call to login() which is required in case of new users.

YES Ankit...
You are correct.
Actually in order to read any user's data from FB, you should have proper permissions and that user should allow you to do so. Then and then only a user access token will be issued to you.

Following is a tested working code for the same.
