.NET components are not the same as namespaces. – Parapet

@MarkRansom: I think he is using C++/CLI – Syncretize

Are you running on windows8 and Vs2012 this are the min requirements if you want to use Windows::Networking::Connectivity – Fatuity

I don't know how one uses Windows 8 apps components, but the MSDN page for a class in this namespace mentions: "Metadata: Windows.winmd ". There is probably something to include or reference in your project. – Veedis

I think you want to use C++/CX (not C++/CLI). The languages are practically identical (in terms of how their syntax looks). But building them is not the same: you enable C++/CX by using the /ZW compiler option (which is turned on by default when you create a Windows Store App).

In the UI, the /ZW option is listed as "Consume Windows Runtime Extension"

well how do I specify that in visualstudio8. I mean the /zw compiler thing? I am running windows8 and visualstudi8. – Cloudburst

@Part, Right-click on Project->Properties. Go to Configuration Properties->C/C++->General and you'll see "Consume Windows Runtime Extension". Set this to "Yes". – Kylynn

there are the following fields Additional Include Directory; Resolve#using reference; Debug Information Format; Suppress Start-up Banner; Warning Level; . . . and the like ... But nothing called "Consume Windows Runtime Extension" – Cloudburst

@Part, I see you said you are on Windows 8 and Visual Studio 8 (not sure what you mean by Visual Studio 8 (hopefully you don't mean Visual Studio 2005). You are required to have Visual Studio 2012 to use C++/CX. – Kylynn

I meant Visual Studio 2008. Thanx for the Information anyways, got a round about way of what I was trying to do. – Cloudburst
