Hi,
Since we did not release the article of how to use Silverlight within the new SDK, I will only give a hint that will help you pass the barrier and then you will continue from there and read the entire manual when it is aired today.
Firstly, in order to have Silverlight support you must select "Silverlight" under SDK and you must make sure that you install "Visual WebGui Projects" component under the "Visual Studio Integration" feature.
A normal "Visual WebGui Project" is also a Silverlight project, this means that in order to activate VWG/Silverlight application you should open a regular project of Visual WebGui and right click on the project to "Enable Visual WebGui" and show the additional project tabs.
Then, within the Deployment tab you should select "Silverlight (GPL)" support. In addition you should add a reference to "Gizmox.WebGUI.Server.Silverlight" assembly (which is deployed by the SDK).
And then if you browse to your form with a .swgx extension, it should work...
But as I mentioned, the article will cover it all later today!
Hope this helps you out...
Regards,
Itzik Spitzen
