I'm using Visual Studio 2017 RC and started a new ASP.NET Core project targeting the full .NET Framework.

This line of code will not compile.

```
 dynamic handler = _container.GetService(handlerType);

 if (handler == null) _logger.LogError("Can't find handler to handle " + cmd.GetType().Name);

```

I get the following error

```
CS0656  Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create'

```

After some Googling it looks like this is because I'm missing the Microsoft.CSharp Assembly. There are plenty of people who have stumbled into his issue but not seemingly with .NET Core 1.1.

So I did this `Install-Package Microsoft.CSharp` and got version 4.3.0. My project still won't build.

If I add an Assembly Reference to Microsoft.CSharp (the GAC'd version) then it Compiles and runs.

Is this a Bug? I would have expected the NuGet package to fix this?
