Naming conventions 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 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.
For example, a WeakRef object can reference a file object.

Microsoft. Wrl Architects Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Microsoft. Herb Sutter, C++ expert at Microsoft, explained during his session on C++ at the 2011 Build conference that the WinRT metadata is CLI metadata. 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. Windows Runtime C++ C++ Copy EventSource
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. 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.
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.
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
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.
