System.IO.FileNotFoundException：未能加载程序集...也许不会在单声道存在Android的个人资料？ [英] System.IO.FileNotFoundException: Could not load assembly...perhaps doesn't exist in the Mono for Android Profile?

问题描述

我试图从Visual Studio（我用Xamarin插上）编译我的Android应用程序时，收到以下错误。

I am getting the following error when trying to compile my Android App from Visual Studio (I am using Xamarin plug in).

2的错误时出现异常装载组件：System.IO.FileNotFoundException：未能加载程序集PresentationUI，版本= 4.0.0.0，文化=中性公钥= 31bf3856ad364e35'。 ？在
Xamarin.Android.Tuner.DirectoryAssemblyResolver.Resolve'PresentationUI.dll：也许它不会在单声道Android的配置文件是否存在。

Error 2 Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'PresentationUI, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Perhaps it doesn't exist in the Mono for Android profile?

文件名（AssemblyNameReference

File name: 'PresentationUI.dll' at Xamarin.Android.Tuner.DirectoryAssemblyResolver.Resolve(AssemblyNameReference

参考，ReaderParameters参数）在
Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences（List`1

reference, ReaderParameters parameters) at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(List`1

组件，装配AssemblyDefinition，布尔TOPLEVEL）在
Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences（List`1

assemblies, AssemblyDefinition assembly, Boolean topLevel) at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(List`1

组件，装配AssemblyDefinition布尔的顶层）在
Xamarin.Android.Tasks.ResolveAssemblies.Execute（）

assemblies, AssemblyDefinition assembly, Boolean topLevel) at Xamarin.Android.Tasks.ResolveAssemblies.Execute()

我身边有一看，发现这论坛帖子它看起来像一个类似的问题。我找不到PresentationUI.dll装配寿。

I had a look around and found this forum post which looks like a similar problem. I couldn't find the PresentationUI.dll assembly tho.

这是为什么我收到此错误，以及如何解决它的任何建议？

Any suggestion on why am I getting this error and how to fix it?

更新

我发现这个问题其实来自于使用DelegateCommand微软.Practices.Prism.dll
是不是因为这个组件不支持Xamarin？

I found that the problem actually comes from using DelegateCommand from Microsoft.Practices.Prism.dll Is it because this assembly is not supported by Xamarin?

干杯，

推荐答案

PresentationUI是WPF的一部分（UI框架在Windows上），这是不是可以在移动平台，如Xamarin.Android。

PresentationUI is part of WPF (UI framework on Windows), which is not available on mobile platforms, such as Xamarin.Android.

您需要重新创建应用程序的移动设备兼容的用户界面，以便Android的准备

You have to recreate a mobile compatible UI of your application so as to be Android ready.

微软棱镜设计与WPF工作，所以是的，你不能在Xamarin.Android项目中使用它。

Microsoft designs Prism to work with WPF, so yes you cannot use it in a Xamarin.Android project.
