As it turns out, we still have no immediate plans to develop controls specifically designed for LightSwitch. At this time what we recommend is using the components from our UI for Silverlight suite. You can use them to build Silverlight custom controls and add these controls in the LightSwitch screens. We have a few blog posts describing this approach:
I understand that this approach might not be what you're really looking for but it is currently the only approach available for utilizing our Silverlight components within LightSwitch. Still, we are actively monitoring our customers' demands and therefore we will keep discussing the LightSwitch support during our planning meetings in future. I would encourage you to follow the UI for Silverlight roadmap
to keep track of the latest development plans for the suite.
Lastly, regarding the missing LightSwitch pages you mentioned, I want to shed some light onto why we had to take them down. Basically we created them when LightSwitch was first released and unfortunately the approach they described was very outdated and didn't work with the latest version of LightSwitch. This is why we instead created the blog posts I described above to demonstrate a sample implementation of a few common scenarios which our customers often have to implement in LightSwitch. I hope they will help you as well and in case you encounter any issues while using our components, please do not hesitate to describe them through our support ticketing system. We will gladly assist you in overcoming them and moving forward with your application.
