At Build 2014, Microsoft introduced features of Windows 8.1 Update that help enterprise developers move apps to modern, touch-enabled, mobile devices while still receiving the value of long-term investments in existing business logic code.
Brokered Windows Runtime Components make this possible by allowing side-loaded Windows Store apps to interoperate with desktop processes outside of the app container. Microsoft provides a
whitepaper, “Brokered Windows Runtime Components for Side-loaded Windows Store Apps” that provides more details.
The instructions in the whitepaper involve many manual customizations on Visual Studio project files and build scripts to make it all work. To simplify these customizations and automate the build process, Microsoft has developed Brokered WinRT Component Project Templates that can be downloaded from the Visual Studio extensions
gallery. They can also be installed from Visual Studio by selecting Tools > Extensions and Updates and searching for “Brokered WinRT Component.” They are listed under Online > Visual Studio Gallery > Templates > Visual C++ > Visual Studio Extensions.
The two project templates include:
1. A C# project template to create the Desktop Windows Runtime components that are used to bridge modern application and pre-existing desktop code.
2. A C++ project template to generate the IPC proxy stub that will be used in the application.
