Question

我尝试在.Net 4.0和.Net 4.5应用程序上安装ServiceStack Framework。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.

    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

和

是什么给出了？

Answer 1

ServiceStack.Interfaces发生的重大变化是它现在是portable library as of v4.0.30支持大多数支持的平台（Profile136）：

.NET 4.0 +
Xamarin.iOS
Xamarin.Android
Windows应用商店
Silverlight 5

如果NuGet报告它无法为受支持的平台找到必要的程序集引用，那么您可能正在使用不包含PCL支持的旧版NuGet，这可以通过{{3来解决}}

Answer 2

升级Nuget＆＃34;选项不适合我。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，因此ServiceStack.Interfaces 4.062是我们可以安装的最高版本。

如何安装ServiceStack.Interfaces？
