Reconnection attempts fail

[Mone]

Hi,

that's an issue with Silverlight. The problem is that if the silverlight engine does not receive the clientaccesspolicy.xml file the fist time it tries to download it, then it will never try again to download it assuming that it has no permission to connect (you can see that if the server is down the exception thrown is security related).
A workaround could be to have some aliases for the server machine and then, if a connection fails due to security problems, try with a different alias.

Hi Mone,

Thanks for your answer... I suspected as much, since I observed that in the faulty case, no requests were sent from the Silverlight API on the net.

However, googling around I found this post
http://forums.silverlight.net/forums...93/263003.aspx

At the very bottom, it is stated that the bug has been fixed in Silverlight 4 RC, so I'd expect the fix to be in the RTM version.

Will a Lightstreamer API that targets Silverlight 4 be released?

Emilio,

Thanks for pointing out that link.

Regarding Silverlight 4, we will be running some tests with Lightstreamer in the next few weeks. By the way, have you already had a chance to test our current API against Silverlight 4?

Ciao e grazie,

Not yet, but I'll be doing it (hopefully) soon.
I'll post an update as soon as I have news.

Hi,

I did some tests with a Silverlight 4 application, Lightstreamer server 3.6 build 1463, SL API 1.2.0.0.

It appears that the client is able to reconnect to the server even if the very first attempt fails, but not always. I did not thoroughly debug the failing cases, but, given the results, I suspect the cause might lie in the Lightstreamer SL API and not in the SL framework.

Going back to my other original question, do you plan to port LSProxy class' functionalities to Silverlight API?

Just to add some new info.
I fixed a couple of problems in my code and reconnection after first failure has never failed again since then.

Emilio,

The current plan is to enhance the Silverlight Demo to show how to manage automatic reconnections and resubscriptions, rather than porting the LSProxy class.

Hi Emilio
Can you share any code sample with us that describes how to perform auto reconnect using SL SDK?

I ran some tests with Silverlight 4 and I confirm that the current library is already compatible with the Silverlight 4 SDK
