应用错误收集

我正在尝试遵循官方的xamarin教程来使用Xamarin Form PCL项目中的WCF服务（URL /指南/跨平台/ application_fundamentals / web_services / walkthrough_working_with_WCF /在Xamarin网站上）

但是，在引用System.ServiceModel nuget包时，我收到以下错误，并且没有安装包：

无法安装包'System.ServiceModel 1.0.0'。您正在尝试将此软件包安装到以“.NETPortable，Version = v4.5，Profile = Profile7”为目标的项目中，但该软件包不包含任何与该框架兼容的程序集引用或内容文件。有关更多信息，请与软件包作者联系。

我也没有运气尝试了配置文件78（因为没有WCF支持，我按照here的说明删除了Windows Phone 8.1。

我按照here的说明为PCL项目尝试了不同的配置文件，但没有成功。

另外，我尝试使用Package Management Console并得到类似的错误：

我如何知道需要选择哪个配置文件才能成功安装System.ServiceModel nuget包？

请注意我使用的是Visual Studio 2015 Professional和最新的Xamarin。
