We've noticed a compatibility issue with a Silverlight 3 app which runs fine with v3.0.40818, v3.0.50106 and v4.0.50401 but refuses to load in v3.0.40624. Instead it gives a message box saying a more recent version of Silverlight is required.
Does anyone know what the changes were between 3.0.40624 and 3.0.40818 or why the app might not be compatible?
I think you'll find that 3.0.40624 is a Beta version of Silverlight 3. You should recommend to any users you have that still have this Beta version to upgrade.

The app is a Xamarin.Forms PCL app running version 2.3.4.231 after an upgrade from Xamarin.Forms v2.2.0.31. The app works just fine on my iPhone 6s running version 10.2.1, however the app crashes on the ListView page when running on my iPad Mini 2 running version 7.1.2. More importantly, neither Xamarin Insights or HockeyApp catches the error.
The app worked just fine with the old version of Xamarin.Forms when both Windows 10 and my Mac Book was running this version of the software. https://releases.xamarin.com/stable-release-cycle-6-service-release-4/
I just upgraded both Windows 10 and my Mac Book to this version of the software. https://developer.xamarin.com/releases/vs/xamarin.vs_4/xamarin.vs_4.4/
I'm now getting this error in the iOS properties section.
It might be important to note that I'm using this in the ListView page. Both packages are installed in the Portable and iOS Projects.
Xamarin.FFImageLoading v2.0.5
Xamarin.FFImageLoading.Forms v2.0.5
I'm just assuming this has something to do with ListView, but I have no idea other than this is where the app is crashing. Any help is much appreciated. Let me know if you need to see some code.
iOS 7 and 8 are no longer supported according to this link. https://github.com/xamarin/Xamarin.Forms/pull/630
If you are using the latest version of Xamarin.Forms 2.3.4 or newer, versions older than iOS 7 are no longer supported. You can see the official documentation here, under "Other Changes"
https://releases.xamarin.com/stable-release-xamarin-forms-2-3-4-224/
It does appear iOS 8 and newer are still supported however.
I have a Silverlight application developed with version 4.0. I tried running it with Silverlight 5 client and everything seems to be fine up to now.
But I am wondering; if my users installs Silverlight 5 for client, is it sure my application will still work well? Do I have to run all my Test Cases again?
If anyone notices something that has been broke between versions, please list it here! :)
Thanks
There's little evidence around the internet at the moment, other than that published by Microsoft, which can be found here and here, which states, to summarise:
Several changes have been made to the Silverlight runtime and the
Silverlight Tools between Silverlight 4 and Silverlight 5. For these
changes, the following principles apply:
Most Silverlight 4 applications will work with Silverlight 5 without
any changes.
When breaking changes are required, Silverlight will try to maintain
support for the old behavior, as well as the new behavior, by using a
quirks mode.
Nevertheless, some changes made to Silverlight components can
potentially cause your older Silverlight-based applications to fail
(compile time, XAML load time, or possibly design time) or to behave
differently.
And,
There are no known breaking changes between Silverlight 4 and
Silverlight 5 in the Silverlight core runtime. Applications that were originally compiled using Silverlight 4 tools, and that continue to target the Silverlight 4 runtime, should work without issues on a client that has the Silverlight 5 runtime.
If your project references any Silverlight SDK client assemblies [...] make sure that your project
specifically references the Silverlight 5 version of the SDK client
assemblies [...]. A project that targets Silverlight 5 cannot use the Silverlight
4 SDK assemblies.
There's more information in the links I provide, for instance, related to quirks mode, third party references, and behavioural changes.
I have a project with a Silverlight 4 tool used to display a barchart etc. The Project upgrade to VS2013 automatically upgraded to Silverlight 5 and there were no warnings. I worked on other areas of the project and only by chance did I actually run it in debug mode to find that the display was broken somewhere inside the tool. I managed to scamper back to VS2012 and scavenge the changes I had made in the VS2013 version of the project.
I updated Silverlight on my dev. machine, but clients still have older Silverlight version and they do not want to update.
Now I need to revert Silverlight 4 back to older version (50401). I tried to uninstall Silverlight and install older version, this required my to install developer tools, too.
No luck, still it requires newer version on clients machines. So I suppose real version is inside developer tools?
The question is, how do I make VS2010 to compile project for specific Silverlight 4 build?
I already stumbled on that kind of problem, and I had to re-install my sdk.
Check out that great article from Tim Heuer:

I've been developing for and running Silverlight 4 for about a week. A week ago I installed the Silverlight 4 design time components to develop and debug silverlight for VS 2010 - I posted some of these apps and they were used by users running SL4. Today, I went to a website that told me to upgrade my SL (I think it was the MS expression site) - so I did that and all the sudden I get this error when running SL 4 apps within VS 2010.
The silverlight developer runtime is not installed please install a matching version
Installing the latest version of the Silverlight SDK does not correct this. Basically I am stuck and unable to run Silverlight apps from VS2010.
Are versioning problems like this a common theme in SilverLight? The only thing I can think of is that there is a minor version difference between the versions used on the the MS Expression web site and the version (SL4) I installed from MS site a few days ago? However re-installing the latest version of SL4 does not correct this.
Any help?
The developer runtime is a different download than the normal "end user" runtime.
Again quoting from Tim Heur's Blog, you need to look for the link under "getting the updates" that points to the developer runtime. This will allow you to debug etc.
How safe is it to use Silverlight in production for a graphic form?
Is it installed on most computers, do to Windows Update feature?
If so, which version is it installed? What is the safest target version?
I don't know whether it's installed on most computers, but the number is growing. It's a small download and if it's not installed the user can install it with a single click.
This page has some graphs:
Adobe Flash is on 97% of computers.
Silverlight is on 55% of computers.
Java is on 73%
I have no idea how accurate these figures are, but they seem to be believable.
Once installed it uses Windows Update to keep itself up to date.
As Anthony states the current released version is 3. Version 4 is at Release Candidate and will probably be released within the next couple of months (as of March 2010). I originally thought that the update would happen automatically, but the RIA Stats page indicated that Silverlight 2 and even 1 were still installed on some machines so this can't be the case.
My company is using silverlight 3, this is the current version, silverlight 4 is currently a RC.
Safest version to target right now is Silverlight 3. At Mix10 it was indicated that Silverlight has 60% coverage.
Windows Update may patch an existing Install I doubt it will push Silverlight or perform a major upgrade (imagine the law suit that would result in).
