无法在 Visual Studio 2013 上为 PCL 配置文件 158 安装包 MvvmCross.PortableSupport 3.2.1

我有以下设置，但仍然无法将 mvmcross 库添加到我的项目中：

1. VS2013更新3
2. Nuget 包管理器 2.8.50313.46
3. PCL Profile 158（我也尝试过其他像 78 等）

安装日志如下：

我将配置文件更改为 259 并且它正在工作。

如果有人不知道如何更改个人资料：

在“解决方案资源管理器”中，右键单击项目名称并选择“编辑项目配置文件”。寻找该行：

<TargetFrameworkProfile>Profile158</TargetFrameworkProfile> 

并将 Profile158 更改为 Profile259。确保其下方的行：

 <TargetFrameworkVersion>v4.5</TargetFrameworkVersion> 

设置为 v4.5 而不是 v4.0，否则在尝试重新加载项目时会收到​​错误消息。要重新加载项目，只需在解决方案资源管理器中再次右键单击项目名称，然后选择重新加载项目。
