Error with Cross Domain Web Services

Today I received an email about numerous unanswered questions on the forums about errors when trying to retrieve data from web services that are not on the same server as the one serving the Silverlight application (Cross-Domain).

ActiveForumPosts

I have a tutorial about to be released (today?) that deals with every aspect of this except the one that is causing the problem: cross domain, but that is okay, because it brings everyone to the same starting point.

Unfortunately, I am also going away for a week: to present on Silverlight at VS Live San Francisco and then to Redmond. But that is good too, because if the problem is not resolved by the time I hit Redmond, I'm seeing just the right people to ask.

In the meantime I'll post the question to an internal newsgroup and let you know if I receive any word. Look for further posting no later than a fortnight, but almost certainly sooner.

Thanks!

Jesse, when you're up there at MS, please tell them they need to have more MS support team on the forum. There are way too many questions being pushed away and get lost without any answer. This will have a serious negative effect on the product's outlook where the vendor is not showing support on the forum. It was like this during 1.1, but I thought things will change for 2. I understand there are just too many people hitting the forum, but if you check, you'll see less than 1% is being checked green(answered) from MS team.

At least an acknowledgment that they see the messages and confirm if it is a bug or not, will be a great help to start with. These are just me personal suggestions to you to take it with you!

I've made suggestion to Simon to have a knowledge base of common problems, bugs and errors that people can refer to, but he didn't give me any concrete answer. He said the forum is the place for Q&A.

Thanks!

Jesse,

Please see this thread:

silverlight.net/.../43694.aspx

It is not just a cross-domain issue. It is also happening on localhost. I did get some good clues about it on my last attack and it appears that if something fails, it ties everything up.

Back to the investigation...
