FYI … the NuGet website now allows you to filter by .NET target frameworks. Useful? What do you think?
You can’t do this in Visual Studio at the moment but the next steps according to the NuGet team are …
target framework awareness to the NuGet protocol so that clients like Visual Studio and CLI tooling can also provide rich experiences for filtering packages.
.. so hopefully it won’t be too long before we can filter in VS itself.
