将 StructureMap 与 Xamarin.Forms 一起使用
Using StructureMap with Xamarin.Forms
我正在开发基于 Xamarin Forms 的跨平台应用程序。
在我的应用程序中，我想为 IoC 使用 StructureMap。
我制作了一个示例应用程序。添加 StructureMap 包 (4.6.1) 后，部署时出现错误：

Failed to debug your app.
我使用 Visual Studio 2017 (15.7.1) 和 Xamarin Forms 3.0.0.482510.
我对 Entity Framerwork Core SQLite 也有同样类型的问题
你遇到过这个错误吗？
我建议您不要在 Xamarin.Forms 上使用 StructureMap，因为它不受支持：
StructureMap 4.5+ will not work on Xamarin iOS because it depends on
System.Reflection.Emit, which is not available in MonoTouch.
StructureMap 4.4 works for at least basic scenarios on that platform.
Nobody in the core StructureMap team is currently working with Xamarin
mobile runtimes, but we are interested in verifying StructureMap on
new platforms if any volunteers are interested in helping us out.
