如何安装ServiceStack.Interfaces？

Question

我尝试过在ServiceStack框架 4.0和.Net 4.5应用程序上安装.Net。我两次都犯了同样的错误：

Install failed. Rolling back...
Install-Package : Could not install package 'ServiceStack.Interfaces 4.0.31'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any 
assembly references that are compatible with that framework. For more information, contact the package author.

和

怎么回事？

Answer 1

ServiceStack.Interfaces发生的主要变化是，它现在是一个支持最受支持的平台(Profile136)的可移植库( v4.0.30 )：

• .NET 4.0+
• Xamarin.iOS
• Xamarin.Android
• 窗口商店
• 银灯5

如果NuGet报告说它无法为受支持的平台找到必要的程序集引用，那么很可能您使用的是不包含PCL支持的旧版本的NuGet，这可以由升级到最新的NuGet解决。

Answer 2

“升级Nuget”选项不适用于我。事实证明，ServiceStack的版本确实有.NET限制。我们的应用程序是.NET 4.0，所以ServiceStack.Interfaces 4.062是我们可以安装的最高版本。
