aardio 范例: 调用 UWP 接口

//调用 UWP 接口 
//标准库 dotNet.ocr, 扩展库 dotNet.toastListener 都运用了以下方法编译 DLL 。
import dotNet.uwpCompiler  

/*
如果参数@2 未指定 Windows.winmd，默认在 C:\Program Files (x86)\Windows Kits\10\UnionMetadata 
最新版本SDK目录下查找此文件，生成的DLL程序集并不依赖 Windows.winmd 文件，仅编译时需要。
*/
var uwpCompiler = dotNet.uwpCompiler( "\ocr.dll" )//"~\lib\dotNet\ocr\.res\ocr.dll" 

//启用编译优化
uwpCompiler.Parameters.CompilerOptions = "/optimize"

//设置待编译C#源码
