UWP应用程序的受限功能

Question

I want to make screen projection application. And according to MSDN I need a rescap namespace in Package.appxmanifest. I Wrote this xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities" , but namespace does not appears. Do I need something more?

Answer 1

In the Package.appxmanifest when you add the rescap namespace, add 'rescap' to the IgnorableNamespaces property.

<Package xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10" 
     xmlns:mp="http://schemas.microsoft.com/appx/2014/phone/manifest" 
     xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10" 
     xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
     IgnorableNamespaces="uap mp rescap">

Edited: VS tells you "Capability" aren't into "rescap" namespace and doesn't let you build the application. Adding the name to the IgnorableNamespaces let you use the "rescap" namespace without breaking the application and letting you use the restricted capability.

Answer 2

To Add "Screen Projection Capability", you can include following two lines in "package.manifest":

xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"

<Capabilities>
<rescap:Capability Name="screenDuplication "/>
</Capabilities>

Besides, you can find a projection sample , which use ProjectionManager and ApplicationViewSwitcher APIs.

To Cristian: I don't think his problem is related with "IgnorableNamespaces", which is more about backward capability.

开发者帐户不能使用特殊功能和受限功能，因为该公司帐户有需要。
