4 Deployment Problems Installing client apps is fragile Will the install of app1 break app2? Traditional DLL hell problem Installing client apps is hard & expensive Must touch every client Both for 1 st time install & subsequent updates Installing client apps is fragile Will the install of app1 break app2?

5 ClickOnce Vision Bring the ease & reliability of web application deployment to client applications.

11 Install Goals Reduce install fragility Allow what’s low impact Ex. App file copy, start menu integration, etc… Can always undo what was installed Disallow what’s not low impact Apps never run with admin rights (LUA) Driver registration, COM objects, etc.. Custom actions; large source of install uncertainty Expand the definition of “low impact” Requires OS Changes. Starts with Longhorn Reduce install fragility Allow what’s low impact Ex.

21 Security: The Sandbox (SEE) Apps run in secure sandbox by default Similar to IE javascript Ensures applications are safe to run Increased sandbox size “Longhorn” > “Whidbey” >.NET V1.1 VS helps author for the sandbox Debug in Zone PermissionCalc Security Exception helper Apps run in secure sandbox by default Similar to IE javascript Ensures applications are safe to run Increased sandbox size “Longhorn” > “Whidbey” >.NET V1.1 VS helps author for the sandbox Debug in Zone PermissionCalc Security Exception helper

22 Security: Sandbox Restrictions Some apps need more permission Un-managed code access Export to Excel or any MS Office integration Un-restricted file access Un-restricted network access Some apps need more permission Un-managed code access Export to Excel or any MS Office integration Un-restricted file access Un-restricted network access

23 Security: Policy Deployment Application level policy “Trust this app” “App” defined by it’s app manifest Baked into core CLR security Trust Licenses License issued by admin, deployed with app License indicates admin says app is trusted Requires only one-time (ever) client touch To configure trusted license issuer Application level policy “Trust this app” “App” defined by it’s app manifest Baked into core CLR security Trust Licenses License issued by admin, deployed with app License indicates admin says app is trusted Requires only one-time (ever) client touch To configure trusted license issuer

24 User Consent Admins should make trust decisions, but… Not always possible Home users are their own admin Users make trust decisions all the time Putting a CD in their computer Installing software Submitting a Credit card to a web page Admins should make trust decisions, but… Not always possible Home users are their own admin Users make trust decisions all the time Putting a CD in their computer Installing software Submitting a Credit card to a web page

25 User Consent Design App request permissions needed Requests specified in app manifest VS helps identify needed permissions Prompt is simple & binary Happens at install / 1 st launch Combined Install & Trust Prompt User prompted if: App needs permissions above the sandbox Admin has configured to allow prompting App request permissions needed Requests specified in app manifest VS helps identify needed permissions Prompt is simple & binary Happens at install / 1 st launch Combined Install & Trust Prompt User prompted if: App needs permissions above the sandbox Admin has configured to allow prompting
