You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.3', but the package does not contain any assembly references that are compatible with that framework. For more information, contact the package author. At line:1 char:16 + Install-Package <<<< ServiceStack + CategoryInfo : NotSpecified: (:) [Install-Package], InvalidOperationException + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

Answer 1

I was facing the same issue and while searching for a solution came to this thread. Based on @mythz's comments of checking the NuGet version I was able to resolve the issue.

You need to go to Tools -> Extensions and Updates -> Updates tab. Find Nuget Package Manager and click the Update button. Once NuGet is updated, you should be able to install ServiceStack.Interfaces without any issues.
