Discussion: Silverlight 4 expectations

SL 3 is almost here (the official release date is the 10th of July), and most of its new features are already known (mainly UI improvements and wider support in other media formats).

SVG -> WPF linear gradient

Does anyone know if there is an equilant attribute of SVG's "gradientUnits=userSpaceOnUse" in WPF for a LinearGradientBrush? I can't seem to find this. If not, does anyone know about how to calculate it in (C# or VB.NET)? For example if I have a StartPoint of 0,0 and EndPoint of 1,1 on a Rectangle that is 100x100, the angle is 45 degree...

What does Silverligtht 4.0 Trusted Mode mean on a Mac?

Are there any special considerations we will need to take into account for Mac scenarios?

Streaming a webcam from Silverlight 4 (Beta)

The new webcam stuff in Silverlight 4 is darned cool. By exposing it as a brush, it allows scenarios that are way beyond anything that Flash has. At the same time, accessing the webcam locally seems like it's only half the story. Nobody buys a webcam so they can take pictures of themselves and make funny faces out of them. They buy a...

Pure C# open source PCM to Mp3 convertor?

Microsoft Silverlight 4 is in beta. It supports PCM audio output. It would be madness to stream PCM over internet (for ex in P2P chart webApp) so we need Pure C# open source PCM to Mp3 convertor. No unmanaged code, nothing going out of .net sandbox. So does any one know such Pure C# open source PCM to Mp3 convertor? What do I need: ...

Silverlight 4 webclient authentication - anyone have this working yet?

So one of the best parts about the new Silverlight 4 beta is that they finally implemented the big missing feature of the networking stack - Network Credentials! In the below I have a working request setup, but for some reason I get a "security error" when the request comes back - is this because twitter.com rejected my api call or some...

UDP Multicast for streaming video with Silverlight 4.0

I've been streaming multicast video using the Project Starlight plugin for Silverlight 3, but now I'm hoping to do the same thing natively in Silverlight 4.0 beta. Using Starlight, the code was straight-forward, and relatively simple...for ex: -1- Generate the proxy as ActiveX: HTML CODE mcObj = (ScriptObject)HtmlPage.Win...

Applying a FontFamily to all Controls in Silverlight 4 Beta

I'd like to give every Control a certain FontFamily and FontWeight in Silverlight 4.0. I know that styles can now apply to all controls of a certain type, so I tried this: <Style TargetType="Control"> <Setter Property="FontFamily" Value="Arial" /> <Setter Property="FontWeight" Value="Bold" /> </Style> Unfortunately, that doesn...

Silverlight - Dual Screens in Out of Browser Application

Is there any way to create a Silverlight "Out of Browser" Application that can have two windows each on it's own screen and have these two windows communicate?

.NET 4 SDK corrupted? with Silverlight 4 Tools install

I installed Silverlight 4 and now my C# projects that use some of the new .NET 4 classes like System.Threading.Parallel and System.Numerics.BigInteger don't appear to be present. Have tried switching between selected frameworks in the project properties, and downloading and running repair on the .NET 4 SDK, but didn't resolve the issue...

Silverlight 4 and TCP Sockets

Most of the software we develop has to communicate with hardware devices in the local network using TCP/IP, UDP/IP or serial ports. This is probably the only reason we still target WPF instead of Silverlight for our UI. Socket support in Silverlight 2/3 is poor at best and way to limited. I've read the updated desktop mode in Silverligh...

Native Integration in Silverlight 4

Hi, a question concerning the new concept of Trusted Applications in Silverlight 4: I gather that trusted applications run outside the browser with elevated trust. Will it therefore be possible to call arbitrary functions in unmanaged DLLs (by means of DllImport) from a trusted application or is this feature still reserved to proper de...
