Question

我是Xamarin的新手，所以我用Xamarin安装了Visual Studio，当我创建一个新项目，然后在没有做任何事情的情况下运行它会给我这样的错误

C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(1410,2): error : Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'System.Collections.Concurrent, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Perhaps it doesn't exist in the Mono for Android profile?

有什么问题？

我运行此命令＆＃34; Install-Package System.Collections.Concurrent＆＃34;在包管理器控制台中。然后去添加引用，然后单击浏览，然后转到C： - ＆gt; windows-＆gt; microsoft.net-＆gt; Framework64-＆gt; v4.0.30319 folder-＆gt;选择system.colection.concurrent.dll-＆gt;单击OK。

无法加载程序集System.Collections.Concurrent版本4.0.0.0
