The fastest way to encourage adoption is to get Silverlight on as many platforms as possible -- Windows Mobile, iPhone, Mac (all flavors), Linux, Android, Windows Embedded, MCML, and so forth. The more platforms, the better.

Get Silverlight on the iPhone
It would be great if we could write Silverlight apps for consumption on the iPhone. Even being able to write apps for the app store. Think if Microsoft could beat Flash to the iPhone.

Consolidate WPF & Silverlight Programming Models
As a WPF developer, moving to Silverlight has been like learning a whole new platform, and while I realize there are some things I might not be able to do related to network access or security, the fact that simple things like how a ComboBox works is different, has me pulling my hair out. So whe... more

Encoding and streaming to Media Server / IIS
To make some use for the webcam/mic support announced for Silverlight 4, some video/audio encoders should be built in (for example Windows Media or h264/AAC). Also there should be built in support for streaming audio/video to either a Windows Media server or to IIS using live smooth streaming.

Add file output support for Excel, PDF, XPS, etc.
In addition to being able to print and offer basic reporting, Line of Business apps need to easily be able to output to Excel, PDF, XPS. If I show a data grid with Sales Data to a VP at my company, they are going to want that data in Excel in one click.

Enhance the rendering bitmap API and GPU usage also using shaders on the GPU
Right now the bitmap APi is primitive and needs more functionality as well as performance enhancements. We also need more functionality on the GPU, especially the shaders and 3D abilities in WPF. This would give game developers some serious power instead of what we have now.

Media Playback variable speed/rate
Ability to change the playback speed of the media element engine, allowing users to listen / view media at 1.5, 2 times the normal playback rate. Needed for playback of long recordings (think lectures) where you want to review lots of material. Akin to WMP implementation where you can set the playback rate

JPEG decoder
Actually, the only way to get the pixels of an image is to load it in a BitmapImage and use the Writeable bitmap. But this has to be done on UI thread. This is restrictive because we cannot load and manipulate image(s) in a background thread before creating the final BitmapSource. The worst case ... more

JPEG Encoder
Actually, it is not possible to generate a bitmap image (using WriteableBitmap) and send the rendered image to a server (or write it in the IsolatedStorage). We have to rely on some 3rd-party library to encode the image. A solution would be to have a JPEG encoder class which simply receive a Pixe... more
