I can authenticate Facebook for desktop application using web browser control. But I want to log in without the browser. Email and password will be given through windows form.I’ve searched a lot, but found nothing on this.

Many people saying that it’s not possible, facebook won’t allow for privacy policy. But applications like tweet deck or nimbuzz are doing that. So I think it’s possible.

I want to use Facebook’s Latest C# sdk.

    It is not possible. See this link:
    https://developers.facebook.com/docs/authentication/

    To quote from that link:

    Desktop Apps

    Our OAuth 2.0 implementation does not include explicit desktop app support. However, if your desktop app can embed a web browser (most desktop frameworks such as .NET, AIR and Cocoa support embedding browsers), you can use the client-side flow with one modification: a specific redirect_uri. Rather than requiring desktop apps to host a web server and populate the Site URL in the Developer App, we provide a specific URL you can use with desktop apps: https://www.facebook.com/connect/login_success.html.

    The reason that this is not possible is that facebook uses the OAuth protocol. More details on the OAuth protocol can be found at:
    https://www.rfc-editor.org/rfc/rfc5849

    The fundamental motivation behind OAuth is so that the resource that needs authorization does not need to know the credentials/identity of users.

    What you are proposing (taking in the clients username/password) goes against the fundamental tenets of the OAuth protocol and you cannot (at least legally) achieve this with facebook.
