NETSTANDARD 1.6 & NET47 cross compile support

I have a package built against both NETSTANDARD & NET47. Here is my csproj;

<Project Sdk="Microsoft.NET.Sdk">

When adding the package in LINQPad I get the following error;




This is strange because I'm using this package in many places, but cannot within LINQPad. Does LINQPad support framework 4.7 or netstandard 1.6?

Using LINQPad 5.22.02, and tried Beta 5.22.09 but got the same problem.

The LINQPad log has some errors in it;

I'm retrieving the package from a Visual Studio Online private NuGet feed.

I'm guessing the problem is not with the output assemblies, but with the NuGet package itself. In order for LINQPad to consume assemblies in a NuGet package, they must be packaged as reference assemblies (in the lib folder). Some NuGet packages do not have any reference assemblies, and use other tricks with scripts and msbuild to add references to the project. LINQPad does not use projects or msbuild, so it needs simple reference assemblies.
