Using SilverLight (WPF/E) creates clear images
Remember migrating from .net 2.0 from 1.1 at your ISP? Our ISP created a separate server with .net 2.0 libraries and selected clients moved their applications to that server. Of course, if the application included Web Service, Web Pages and Windows Client, ALL code had to be converted to .net 2.0 before it was deployed.
Migrating to Microsoft .net 3.0 is MUCH simpler, because the ASPX server is still a ASP.net 2.0 Server. Of course, our ISP seems to be taking a 'measured' approach. But does that stop us from playing with .net 3.0 and wanting to show our endeavors? Of course not.
Do you get annoyed when images are not clear on web pages because of rescaling? The really cool facet of .net 3.0 is Managed Code directly accessing un-managed code, namely DirectX. Use XAML - a new, mark-up language to build user interfaces with.net 3.0 libraries. Images can be displayed with amazing clarity.
Using Microsoft Expression Design, we created a simple WPF/E image control that displays thumbnails and allows the user to select an image that scales. Look at the clarity of this image. So how did this code reach the web?
1. Post code to ISP. Problem - XAML file type not recognized and hence the control did not display at all.
2. Change XAML file type to XML file type - control now displays!
3. Login to ISP technical page and chat with support staff. Ask them to add the XAML file type to the web server (use same characteristics as XML file type).
4. WPF/E control now displays in a web page from our ISP.
5. Go to 'virgin' PC (one that hasn't used .net 3.0). Open web page with WPF/E control. Because this control is a WPF/E control, the page displays a note that the WPF/E plugin needs to be downloaded. Click to download.
6. View fantastic WPF/E image selector control with great image clarity.
