Noticed this feature was available in VS2015, but didn't see as most of my class projects are portable. This would be nice to add to portable and .NET Core v1 projects.

Any chance to get it soon? It is very frustrating when something excellent from previous version is removed in new.

What... How is this not a priority?

[reinux]

Are there any workarounds for this?

So far, to use Entity Framework for SQLite, I've loaded all this manually, testing after each #r to see if it'll finally run:

```#r "C:\Users\rei.nuget\packages\microsoft.extensions.caching.abstractions\1.1.1\lib\netstandard1.0\Microsoft.Extensions.Caching.Abstractions.dll"

r "C:\Users\rei.nuget\packages\microsoft.extensions.options\1.1.1\lib\netstandard1.0\Microsoft.Extensions.Options.dll"

r "C:\Users\rei.nuget\packages\system.interactive.async\3.0.0\lib\netstandard1.0\System.Interactive.Async.dll"

... And it's still asking for more, so I gave up. I imagine this is a deal-breaker for a lot of people. Are people just not using CSI?

@reinux Maybe a bit off topic, but I personally never use it. It's too stunted; easier to just make a new console application as a scratchpad.

[shaggygi]

Not to be a thorn... Just wanted to ping again to add my vote that this is such a great feature. Hope to get with .NET Core/Standard projects at some point. CC @davkean

@reinux This is why I'm not using it. When this works right it's a crucial tool.

[davkean]

Microsofties this PR: https://devdiv.visualstudio.com/DevDiv/_git/CPS/pullrequest/122409?_a=overview makes this feature show up the new project system when the project is targeting .NET Framework. I'm going to file a new bugs against Roslyn to make it work for platforms other than .NET Framework.

[davkean]

Filed https://github.com/dotnet/roslyn/issues/26934 for the work to add support for .NET Core/.NET Standard. There is no more work on the project system side, the rest is on Roslyn.

[davkean]

This has been merged, dotnet/roslyn#26934 is tracking making this work for .NET Core/.NET Standard. This currently only works in new project system when targeting .NET Framework.
