It shows how to define a managed Windows Runtime type, create an instance of the type from JavaScript, and call static and instance members.

For example, if you return Dictionary to JavaScript code, it appears as IDictionary no matter which interface you specify as the return type. The focus here is on implementing an asynchronous operation, so simplicity is important, and a slow implementation is an advantage when we're demonstrating cancellation. An event must be fired on the component side and handled on the UI thread, and the progress value must be stored on each iteration. Windows Runtime Component Vs Dll Failure to do so prevents subsequent debug or build operations.

They are not required, and in this example, we'll replace all of the generated code with our own code.To create the C++ component projectOn the Visual Studio menu bar, choose File, See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Developer resources Microsoft developer Windows Windows Dev Center Windows There are fewer restrictions on a simple class library.This article contains the following sections:Declaring types in Windows Runtime ComponentsInternally, the Windows Runtime types in your component can use any .NET Framework this contact form Then press F5 to run with debugging, or Ctrl+F5 to run without debugging.Inspecting your component in Object Browser (optional)In Object Browser, you can inspect all Windows Runtime types that are defined
