Today we released a service update for Silverlight 4.  This is a minor release that addresses some items found immediately after release that have now completed our test passes with those who reported them.  Most of the items found won’t affect all users, but media developers will want to get this update for their applications and encourage their users to upgrade.

This update (4.0.50524.0) addresses a few media-related items found by some of our media customers.  A few items were serviced for DRM users as well as 2nd monitor usage for media on the Mac platform.  If you are developing media solutions (or are a media application user), you’ll want to upgrade to this release and encourage your users to as well.  You can read more about the key specific issues in KB982926.

For Developers

If you are a developer and want to get the update, all you need is to update the developer runtime.  There is no tooling or SDK update for this release.  You can download the updated developer runtime here: Windows developer runtime or Mac developer runtime.  Once installed, your new Silverlight 4 applications will target this platform version.  No other changes to your tools are required.  On existing applications if you want your users to ensure they have this latest version, please ensure you update your <object> tag to increment the minRuntimeVersion attribute to the appropriate version (4.0.50524.0).

What about <fill-in-the-feature-issue-you-found>?  Why isn’t that in this update?!

Some may wonder how fixes get determined to be in which releases.  You may be asking hey I reported XYZ right after release and why isn’t it in this update!?  Our team, like other large teams, operates on a schedule of planned (and sometimes unplanned) releases. 

We have general timeframes for service releases in the event we need them.  Sometimes those planned cycles aren’t needed and the planned release is skipped.  This helps better plan actual resources, etc.  When an issue is identified from any type of customer, it is evaluated by the ‘triad’ for that release (a triad represents leads for program management, dev, and test).  Things like security issues are given obvious priority versus things that aren’t regressions or are new features.

Once that list of work items is determined (based on criteria set by the triad) the work begins.  This includes development, testing, compliance, security passes, etc.  Each time a change to the plan occurs, this process gets reset.  So once a set of work items is approved and determined to be the release it usually doesn’t change unless something significant.  Of course there are many other factors that are involved here and I’m generalizing.

Back to your question of where are my reported changes?  If they aren’t in this release, they are still being evaluated for the next cycle (or perhaps already being worked on and solved).  Once I have more information on future releases I’m happy to share them.

Hope this helps!

What is the difference between a user control and a page. I followed your sample and, when you add a new page inside Belnd 4 RC, it actually creates a user control in XAML and not a Navigation page.

Comparing that to the default page helped me discover this. Can you talk about this a little.

thanks

Is this a SL4 or a SL3 update?

On my SL3 system this update appears within the Windows Automatic Updates.

Because we are developing a SL3/VS20008 based solution, it's critical to apply this update!

Tim I am sure this is more than you want to do in a service update but PLEASE!!

RichTextBox .Xaml property should work for databinding !!!!
seems like they meant to make that work and left out some code inside it.
PLEASE get them to fix that - I do not think it breaks any code and it will make using it much simpler in RIA and declared binding useage that many folks expected to work and have been stubling on the failure of it.

Jonathan - the memory leak (DataTemplate) issue is not in this service release. It was identified after this cycle was already in process with final testing. We expect that issue to be addressed in a future service release, looking like end of summer.

Jani - this is a Silverlight 4 update.

Denny - It is a good suggestion as a new feature. Be sure to suggest it for the list http://silverlight.mswish.net or vote on an existing item if it already is in there.

Thanks Tim,

If this is a Silverlight 4 update, why it occurs on my Silvelright 3 computer?
6/4/2010 7:31 AM | # re: Silverlight 4 minor update–June 2010
Jani -- all updates are offered to the user if you have auto update enabled (and they are also offered via Microsoft Update mechanisms). Silverlight 4 is backward compatible with SL3 and we consider this an upgrade. We will always offer the upgrade when available.

Tim: if you look at the silverlight.net forums and at how the RTB works the xaml property is the only one you can possibly databind with. and it even looks like it was meant to. but it does not.
right now there is no way to bind it directly.

IMHO is't a flaw in the control that should be a "Fix" not a "Feature"
look at all the other text controls, they can be bound, the grid can be bound, the list can be bound but not the RTB.

Hi,

We have a policy in my company not to use products which are not WAC. My question is is Silverlight 4.0 WAC complaint.
If so then is there any documentation which tells so.
Thanks

amyo -- thanks for pointing out the beta notation. If you actually omit the version string from the FWLink you'll always get the latest for the platform.

Hi..

Just wondering if there is any potential conflict between having the Developer Runtime installed via the tools and any subsequent update that might come via something like WSUS. Right now, I have WSUS wanting to put KB 982926 on my machine but I don't know if I should accept it in case it knocks out any dev/debug capabilities.

Should I accept the update but then replace by getting the latest Developer Runtime?

Simon -- for a developer you should apply the developer update which is linked above.

I'm getting the same error

System.NotSupportedException
Could not find Microsoft Silverlight SDK v4.0. Plase make sure that the correct version of the Microsoft Silverlight SDK has been installed.

I have VS2010 on Win 7 and I have installed Silverlight 4 but when I checked the registry I couldn't find the key in Microsoft SDK for Silverlight. Any idea to solve this?

Liz - If this is for development of Silverlight applications and you are getting this error in Visual Studio, then install the Silverlight 4 Tools for Visual Studio from http://silverlight.net/getstarted

Thank you Tim for the suggestion but the version I'm using is that one. I do not know what other option I can try. I have tried SL3 and SL4 and I'm still getting the same error.

Was there a solution to this error? I'm now getting after updating the to latest runtime:

This one is only related to SilverLight. Our ever-changing displays of featured titles can be inspired by wildly imagined themes. Sometimes these are based on current events, sometimes on great writing and sometimes the connections are so loose that we will have contests to determine the links.

I'm having the same Silverlight 4 SDK not found error. Tried just about everything I can think of and I'm at a loss, had to move to another machine just to get some work done. You've got people on the forums pulling their hair out, doing crazy stuff to their systems just to be able to get back to work. Is there ANY guidance from Microsoft on this, Tim?

Applications and games you build with the tools released today can be uploaded to the Windows Phone Marketplace - which enables any p
hone consumer to easily download and purchase them directly from their phone. This provides a great way to distribute applications
games that you either get paid for or distribute for free.Visum Incoming Versicherung

Detail pages typically use the Pivot control, which is effective when separating multiple data sources or types revolving around a specific
topic (like social networks). This is why you see Pivot controls being used for contacts and profiles.
