In Browser Trusted Apps SL4: OOB apps run trusted with user consent SL5: in-browser trusted apps with admin consent Set permissions via group policy Uses Authenticode certificate No prompts or installs

Creating a Trusted App Just like SL4 trusted OOB

Creating a Trusted App Sign the.xap Same as for a trusted OOB In Visual Studio or on command line signtool.exe sign /v /f nameOfCert.pfx /p " " nameOfApp.xap signtool.exe sign /v /f nameOfCert.pfx /p " " nameOfApp.xap or

Permissions in Group Policy Actually, only one permission – trusted or not Network admin specifies which publishers are trusted Same as ClickOnce Xaps are associated with publishers by Authenticode Apps from localhost: are automatically trusted

Unrestricted File Access

P/Invoke P/Invoke lets you call native code COM (SL4) also lets you call native code Anything you can do with COM can also be done with P/Invoke Strongly typed No COM registration P/Invoke is optimized for Win32 APIs & native C/C++ code COM is optimized for COM Automation APIs, eg Office COM & P/Invoke are available on Windows to trusted apps

P/Invoke Works exactly like it does in.NET Framework [DllImport("kernel32.dll")] static extern int GetDriveType(string lpRootPathName); … int type = GetDriveType(drive);

WebBrowser In-Browser Use HTML inside Silverlight apps To reuse existing HTML/ASP.NET content To integrate with outside websites In SL4, only OOBs got WebBrowser (WebOC) In SL5, in-browser WebBrowser support (WebOC/IE) Trusted only!

Performance Faster Startup Multi ‐ core background JIT support for improved startup performance. XAML Parser performance optimizations Improved Graphics stack The graphics stack has been re ‐ architected Bring over improvements from WP7, such as Independent Animations. Network Latency optimizations Text layout performance improvements Hardware acceleration is enabled in windowless mode with Internet Explorer 9

64-bit Support 64-bit machines & apps are becoming increasingly common SL5 can run in a 64-bit process 64-bit browsers Sidebar on 64-bit Windows
