Lightstreamer Embraces .NET and adds AJAX-Comet to Microsoft ATLAS

Milan, Italy -- August 25th 2006 -- Lightstreamer, the high-performance AJAX-Comet engine, has been extended with the .NET Technology Toolkit and now provides an option for feed integration by writing Lightstreamer Adapters with Microsoft .NET languages.

Lightstreamer is a push engine conceived for live data distribution to any kind of client application (thin, thick, mobile, etc.). In the case of thin clients, it relies on the AJAX-Comet paradigm to stream real-time data to any HTML browser without the need to download or install anything on the client. The optimized use of HTTP together with bandwidth control and adaptive streaming techniques results in a robust, efficient and highly scalable data delivery.

Lightstreamer Server can be integrated with any data feed through custom Adapters that previously had to be written in Java. Now a toolkit has been released that provides the option to write the Adapters with Microsoft .NET languages.

"The core of Lightstreamer Server is a high performance and very robust Java component, with six years of maturity" said Alessandro Alinone, CTO of Lightstreamer. "Now the market has asked us to open up Lightstreamer interfaces to .NET technology. We have responded to these requests on three levels: server-side integration, thick client-side integration, thin ATLAS client-side integration."

On the client side, an on-line demo has been released which shows an ATLAS (Microsoft’s AJAX toolkit) front-end updated in real-time by Lightstreamer (, this shows how it is possible to extend AJAX with the Comet paradigm.
An alpha version of the Lightstreamer .NET client library is also available, so that any .NET client application is able to receive live data from Lightstreamer Server.

About Lightstreamer
Lightstreamer is a high-performance, Java-based push/streaming engine based on the AJAX-Comet paradigm that delivers real-time textual data to Web browsers and to desktop applications. When using browsers as a client, nothing is installed or downloaded (no applets or ActiveX, but only pure HTML/JavaScript). Lightstreamer was originally developed by the Financial Systems Integration activity of privately held Par-Tec SpA group (founded in 1998). In 2004 a separate company was formed within the group as an ‘ISV’ to provide Lightstreamer 'Push' middleware solutions for streaming real-time Market Data, or any live information, to web browsers and custom application clients. Lightstreamer is compatible with many browsers on the market, such as Internet Explorer, Firefox, Opera, Netscape, Safari, etc. For more information see  where several on-line demo’s are also freely accessible.
