How do I clear the Facebook Share's Cache?

Sometimes you have a new description, title or thumbnail image in your website. But when you share the website URL on Facebook, it may still using the old description/ title/ image that no longer exists.

In order to clearing the Facebook sharer cache, there are few different ways like using tinyurls or modifying the URL by adding query strings. Since Facebook considers each one as different URL this might be quick way to do it.

The best and preferred way is to use Facebook Debugger tool which is formerly known as URL Linter to clear fb cache of your website. Go to below link and Type your website's or article's URL there and click debug button..

Facebook.NET

Facebook.NET provides a .net library for use in developing Facebook applications and accessing Facebook APIs. The library primarily geared around and optimized for developing ASP.NET-based Web applications, both FBML and IFrame-based Facebook applications through an intuitive API and small set of server controls. It does support the use of the Facebook API from desktop applications as well, and will eventually enable Silverlight application usage.
The library is built on .NET 2.0, but should run on future versions of the .NET framework as well. Applications using Facebook.NET can be written in either C# or VB.NET.

RockMelt, the Social Savvy Browser

RockMelt, a new browser that lives in the cloud and uses Facebook authentication to synchronize a user’s browsing experience across machines, went into limited public beta today.

It was built around the premise that the browser is busted. The thought is that older browsers aren’t made for the way we now use the web, and maybe it’s a solid way of thinking. After all, browsing is a passive activity, and the Internet is increasingly about interaction.

There are some unique concepts here, namely the fact that RockMelt lives in the cloud. This allows your “browser experience” to be, in a way, profiled. Your settings, bookmarks, etc., are all backed up online.

Using Facebook for authentication, your user environment can be replicated anywhere RockMelt is installed. And really, that’s what RockMelt is all about: The user environment.

Users of Google Chrome will feel at home, because RockMelt is built on Chromium, the open source project behind Google’s browser. The major differences are columns running down each side of the browser.

The left side depicts your favorite Facebook contacts. When a contact is listed on the left bar, you’ll be able to quickly initiate Facebook chats with them or post content to their Facebook walls. You can also easily send them e-mails through the seamless contact pop out.

Straddling the right side is your bookmarks — and here’s another area where RockMelt’s cloud is put to clever use. Bookmarks are updated from the cloud, so content is cached and waiting for you when you log on.

All in all, RockMelt is an interesting twist on the browsing experience. The social elements of the browser make for a compelling and streamlined online interaction process. And because it’s powered by Chromium, it not only supports Chromeextensions, it’s guaranteed to support the latest and greatest aspects of the web, like HTML5 and CSS3.

• Facebook.Silverlight.dll: This is the Silverlight version of the main assembly that will be used by all Silverlight applications. This has all the logic to handle communication with the Facebook application. This assembly also has specific support of XAML applications to enhance the Facebook platform to make databinding and data caching easier.
