Release separate nuget packages for netcore.
Hello. I cannot to use ServiceStack.Api.Swagger in VS2017 because it automagically selects net461 version of the library. This can be a quite generic problem for packages containing dll for several platforms. VS2017 project format disallows me to use hint path (it uses target framework attribute) to explicitly select library. Thus, if your net461 exe app refers to netstandard project that uses Servicestack.Core you cannot refer any "mixed" nuget from exe. Please fix it for swagger. Thank you for consideration.

All the available .NET Core only NuGet packages are listed on: http://docs.servicestack.net/templates-corefx#reference-core-packages
Swagger is not included because it implements the older and deprecated Swagger 1.2 spec. Reference ServiceStack.Api.OpenApi.Core NuGet package instead to reference the newer Swagger 2.0 version.
If for some reason you need to use the older version you can build it from https://github.com/ServiceStack/ServiceStack/tree/master/src/ServiceStack.Api.Swagger
