In WinRT, interfaces are passed by reference; all other types are passed by value. HString domainName; hr = uri->get_Domain(domainName.GetAddressOf()); if (FAILED(hr)) { return PrintError(__LINE__, hr); } // Print the domain name and return. If you’ve inherited a code base that uses COM, or one that doesn’t use exceptions, you might find that the WRL is a more natural way to work with the Windows Method overloading All WinRT languages (.NET, C++, JavaScript) support overloading on parameters .NET and C++ also support overloading on type. have a peek here

Naming conventions[edit] The naming conventions for the components (classes and other members) in the API are heavily influenced by the .NET naming conventions which uses camel case (specifically PascalCase). This documentation is archived and is not being maintained. Restrictions and rules[edit] Since Windows Runtime is projected to various languages, some restrictions on fundamental data types exist so as to host all such languages. This is made possible by the metadata.

Herb Sutter, C++ expert at Microsoft, explained during his session on C++ at the 2011 Build conference that the WinRT metadata is CLI metadata.[8] Native code (i.e., processor-specific machine code) cannot

It defines a programming model that makes it possible to write object-oriented code that can be shared across programming languages, and enables services like reflection.

Although you can use JavaScript to access the Windows Runtime APIs, JavaScript cannot easily access native C++ libraries or .NET Framework class library functionality.

For example, you might create a component in C++ that uses a third-party library to perform some computationally expensive operations. When coding a WinRT app in JavaScript, its features are adapted to follow JavaScript naming conventions, and namespaces are also mapped to JavaScript objects. Wrl Racing

In WinRT, only parameter number is used for overloading. Channel9.msdn.com. 2011-09-14. The application dispatches the API call, which returns immediately, freeing the application to perform other tasks while waiting for results.[16] The asynchronous model requires new programming language constructs (keyword async and http://evollux.net/windows-runtime/windows-runtime-library.html C++ Copy // Initialize the Windows Runtime.

One of the major additions to WinRT relative to COM is the cross-application binary interface (ABI), .NET-style generics.

But there are those situations where some people will want/need to avoid C++/CX (whether for portability reasons or for exception avoidance or whatever) and in those cases there's WRL.

This is why C++ is back in fashion."I seriously doubt developers using .NET are going to jump ship and start programming in the new COM"Too bad, .NET is already legacy, your C++ Copy // Create a string that represents a URI. For example, WinRT objects may be allocated with ref new, which is the counterpart of gcnew from C++/CLI. Windows Runtime Api The reason for that is that, as you pointed out, WRL (like COM) has a lot of repetition and boilerplate code.

In terms of COM/WRL C9 conversations, have you watched these? ->http://channel9.msdn.com/Shows/C9-GoingNative/GoingNative-2-C-at-BUILD-Windows-Runtime-LibraryWRL-Meet-Tarek-and-Sridharhttp://channel9.msdn.com/Shows/C9-GoingNative/GoingNative-4-Jim-Springfield-on-ATL-GoingNative-Conference-Register-TodayI'll try to see if we can get Erik to interrogate (in a nice way) somebody who actively maintains COM in Windows 8 app developer blog.

You can use your component in Universal Windows Platform (UWP) apps with C++, JavaScript, Visual Basic, or C#.

When authoring a WinRT component in a managed language, some extra, COM-style rules must be followed, e.g. .NET framework collection types cannot be declared as return types, but only the WinRT Sure, some tools make it easier to make mistakes if you don't have enough experience using them, but you can't blame the saw for removing your finger - it just did The WindowsGetStringRawBuffer function retrieves the underlying Unicode form of the URI string.Here's the complete example: C++ Copy // wrl-consume-component.cpp // compile with: runtimeobject.lib #include #include #include #include I'm in the process of watching Herb Sutter's video on Windows Runtime.

You might be comfortable with WRL if you're familiar with ATL.WRL supports the COM functionality that is required for Windows 8.x Store apps. If you are writing standard GUI apps, I don't see what the point is.
