  1. Clean the Imaging project.
  2. In the DemoCs project, add a reference to platform.winmd.  Browse to "Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\platform.winmd" and add a reference
  3. Now add a reference to Imaging project.
  4. Try rebuild

This worked for me using your project.

What you are observing is possibly a temporary bug in the Developer Preview.  But if you can send me your app, I can certainly take a look.

  • The components you create using C++/CX as shown in this video are fully native components.  There is no managed aspect to them.
  • The fact that underlying technology is COM (not pInvoke btw) is irrelevant.  The whole point is that the developer doesn't need to care about that.  He can write regular C++ language and libraries constructs (with some new additions off course) and he gets language interop for free
  • What's wrong with calling an app that uses both JavaScript and C++, a hybrid app?  Who said that the word "hybrid" is reserved for native+managed interop?

Now before I answer your questions, let me just ensure that you understand a few things: you can use several tools to build applications for Windows 8.  XAML with C#, XAML with C++, DirectX with C++ and HTML/JavaScript are some of those.  Using compiled languages like C# and C++ you could always tap into the OS.  Now you can do it using JavaScript also.  But do understand that when you are creating application with HTML/JavaScript, you are NOT extending the browser.  The application you write is a standalone application that runs directly on the OS.

Also, the purpose of this video was very specific.  If you understand and like the concept of building Metro style app (not browser plug-ins) using HTML and JavaScript, then you can use C++/CX for computation intensive jobs that you app may want to perform.

Now to your questions (those I can answer):

> Can you create NEW C++/CX UI Controls?

For apps written using HTML/JS you cannot, but for apps using XAML for the UI, you can.

> Can you write a game in the browser?

Once again, the browser doesn't come into the pictire in the traditional sense.  If your question is whether you can create apps that are games using HTML/JS, yes you can.

Thank you

Raman Sharma, Visual C++

About your second question: All Metro style apps run in their own sandbox and are thus safe to the extent that is afforded by the sandbox.  This sandbox prevents unauthorized access to system resources.  This means your C++/CX code can execute whatever calls it is allowed to by the Metro style SDK.  If your app package (containing all your app contents like HTML, JS, C++/CX DLLs etc.) passes App-Store validation, then it is safe to run on any machine.  In this sense these apps are more secure than ActiveX controls since there never was any validation that ActiveX is doing the right thing.

For Metro style apps on the other hand, we have three levels of validations: at build time, at package upload time and at runtime.
