This sample shows how to create an in-process DLL component in Microsoft Visual C++ that's used in C++/CX, JavaScript, and C# client code.

The OvenServer project contains a runtime class named Oven, which implements an IOven interface and an IAppliance interface and shows how to declare properties, methods, and events by using the Microsoft::WRL namespace. For more info, see Windows Runtime C++ reference.

The WRLInProcessWinRTComponent_server project produces a DLL named Microsoft.SDKSamples.Kitchen.dll. The WRLInProcessWinRTComponent_server project is built into the Visual C++ component extensions (C++/CX) project by including the generated header file, Microsoft.SDKSamples.Kitchen.h. The WRLInProcessWinRTComponent_server project and its corresponding proxy/stub project are referenced directly in the provided JavaScript and C# projects.

Also, the sample shows how to use the RoOriginateError function to report an error and an informative string to an attached debugger.

You can implement an out-of-process server by using the Microsoft::WRL namespace. For more info, see Creating a Windows Runtime EXE component sample (C++). Also, you can implement a component by using C++/CX. For more info, see Creating a Windows Runtime in-process component sample (C++/CX).

To obtain an evaluation copy of Windows 8.1, go to Windows 8.1.

To obtain an evaluation copy of Microsoft Visual Studio 2013, go to Visual Studio 2013.

Note  For Windows 8 app samples, download the Windows 8 app samples pack. The samples in the Windows 8 app samples pack will build and run only on Microsoft Visual Studio 2012.
