    Arrow Silverlight Beta-Test Program

    [NOTE 03-01-2010: With the official release of the Lightstreamer Silverlight Client library as part of the Lightstreamer distributions, this thread is now closed and the download links in this posts have been removed]

    I'm happy to announce that we are starting today a public beta-test program for the Lightstreamer Silverlight Client library.

    An online demo is available for direct testing (follow the link, wait for the "Lightstreamer is pushing..." message to appear, then click the "Subscribe" button).

    Feel free to download the Beta Silverlight SDK from the link below, then please report back to this thread any comments you may have.

    Prerequisites


    Downloads

    Lightstreamer Server update to v.3.5.1 build 1436
    Legal Disclaimer: By clicking on the link below you understand and accept that the Silverlight SDK for Lightstreamer is a "beta" release, is provided AS IS, and is not yet covered by any of the warranties contained in any license agreement you may have in place with Lightstreamer.
    Lightstreamer Silverlight SDK v.1.0.3391.21925 beta 2

    Instructions
    1. Copy lightstreamer.jar to the lib folder of your Lightstreamer installation, overwriting the existing file.
    2. Copy the <silverlight_accesspolicy_enabled> and <silverlight_accesspolicy_path> elements from the new lightstreamer_conf.xml file to your existing conf/lightstreamer_conf.xml file.
    3. Follow the README.TXT files included in the Silverlight SDK.


    Notes
    • The Silverlight client library for Lightstreamer implements the "Stream-Sense" feature, which allows the client to automatically switch from streaming mode to smart-polling mode whenever some anti-virus software is blocking the streaming connections.
    • Upon a disconnection, the client library does not automatically reconnect and does not automatically resubscribe to the current items. This feature is currently available for the JavaScript and ActionScript client libraries only, and not for the others (including Silverlight).


    Enjoy!

    Hi, I have just downloaded the demo off the site which doesnt have any of the silverlight SDK stuff in. So, I am trying to use the beta project with the server. In visual studio I am going file>new project> from code as you dont supply a .sln file. I get loads of errors coming up around missing bits and pieces. I'm sure there is a lot I am doing wrong. Can you point me in the direction of your latest silverlight SDK and the trader example please?

    thanks,

    MaTT

    Thanks for pointing that out!
    The links are now working fine. Sorry for the inconvenience.

    By the way, the final version of the SDK will be released pretty soon together with updated version of all the Lightstreamer components. This is going to be quite an important release.

    That's great: we are heavy users of the current beta 2 SDK, so it would be very helpful to have the final release version ASAP.

    Now that the Lightstreamer Silverlight Client (v.1.2) has been officially released as part of the latest Lightstreamer distribution, this thread can be closed.

    The official version of the Silverlight Client introduced some changes with respect to the beta version, as detailed in the change log below.

    1.2.3624.21130
    (compatible with Server since 3.5.1)
    (compatible with code developed with the previous version)
    Released on 16 Feb 2010

    Introduced properties in place of fields in the ConnectionInfo
    and ConnectionConstraints bean classes; using the fields is now deprecated.
    Introduced properties in place of getter methods in the SimpleTableInfo and
    ExtendedTableInfo bean classes; using the getter methods is now deprecated.
    Introduced properties in place of getter methods in the IUpdateInfo interface;
    using the getter methods is now deprecated.

    Changed the API documentation format. Now HTML documentation is provided.
    This significantly increases the size of the package.

    Introduced a common base class for the various Exception classes defined.

    1.1.3537.25900
    (compatible with Server since 3.5.1)
    (may not be compatible with code developed with the previous version;
    see compatibility notes below)

    Officially included in Lightstreamer distribution.

    Ensured the compatibility for inclusion in Silverlight 3 projects,
    though the library is still compiled with Silverlight 2 SDK.

    Allowed for configuration of the Stream-sense feature; see the new
    enableStreamSense and streamingTimeoutMillis properties in the ConnectionInfo
    class.

    Extended the OnSessionStarted method on the IConnectionListener to notify
    whether streaming or polling mode is in use; when the Stream-sense has been
    exploited, this may no longer correspond with the requested mode.
    COMPATIBILITY NOTE: existing clients have to be modified and recompiled,
    so as to reimplement the modified method.

    1.0.3524.20170
    (compatible with Server since 3.5.1)
    (may not be compatible with code developed with the previous version;
    see compatibility notes below)

    Extended the PushUserException in order to report the error code and message
    supplied by the Server upon refusal of a connection or subscription request.
    Previously, a PushServerException with id SERVER_REFUSAL was returned in
    the same cases.
    COMPATIBILITY NOTE: existing clients that perform recovery actions upon a
    PushServerException may have to be extended.

    Added OnEnd in IConnectionListener to provide support for the Server
    notification for sessions forcibly closed on the Server side.
    COMPATIBILITY NOTE: existing clients have to be extended accordingly.

    Fixed a bug that might cause a batch not to be closed after an obsolete
    unsubscription request.

    Fixed SetRange in ExtendedTableInfo, which should have been ignored; it
    should not be used, though.

    Used a dedicated thread for all the calls to the IConnectionListener.

    Clarified the documentation for what concerns the thread model.
    Added cloning support to all value objects that can be received from custom
    API invocations and used clones when storing them internally.

    Added support for mocking the library for custom code testing purpose.
    The UpdateInfo class has been turned into an interface and named IUpdateInfo.
    All the exceptions and all the other classes whose objects may be created
    by library code and supplied to custom code now have a public constructor
    and can also be instantiated by custom code.
    Note: the LSClient class is instantiated only by custom code and can be
    freely subclassed or wrapped.
    COMPATIBILITY NOTE: existing clients that use the UpdateInfo class have to be
    modified.

    Added getter methods for the various settings in SimpleTableInfo and
    ExtendedTableInfo.

    Fixed a typo in the example README.TXT, about the Server configuration flag
    to be set.

    Silver light is a web application framework that provides functionality similar to those in Adobe Flash, integrating multimedia, graphics, animations and interactivity into a single run time environment. Initially released as a video streaming plug in, later versions brought additional interactivity features and support for CLI languages and development tools. The current version 4 was released to developers on 12 April 2010, and the end-user run time was released on 15 April 2010.
