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

Question

我有以下设置，但仍然无法将 mvmcross 库添加到我的项目中:

VS2013 更新 3

Nuget 包管理器 2.8.50313.46

PCL 配置文件 158(我也尝试过其他类似 78 等)

安装日志如下:

You are trying to install this package into a project that targets 'portable-net45+win+wp80+Xamarin.iOS10+MonoAndroid10+MonoTouch10', but the package does not contain any assembly references or content files that are compatible with that framework.

我将配置文件更改为 259，它正在工作。

如果有人不知道如何更改配置文件:

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。寻找线:

<TargetFrameworkProfile>Profile158</TargetFrameworkProfile> 

并将 Profile158 更改为 Profile259。确保它下面的行:

 <TargetFrameworkVersion>v4.5</TargetFrameworkVersion> 

设置为 v4.5 而不是 v4.0，否则您将在尝试重新加载项目时收到错误消息。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。
