Description
Hello,
I ran into an interesting problem with dotnet-script. It appears that it cannot use the 0.8.2 version of StateSmith because StateSmith uses a newer version of 'Microsoft.CodeAnalysis.CSharp`.
dbug: Dotnet.Script.Core.ScriptCompiler[0]
Suppressed diagnostic CS1705: error CS1705: Assembly 'StateSmith' with identity 'StateSmith, Version=0.8.2.0, Culture=neutral, PublicKeyToken=null' uses 'Microsoft.CodeAnalysis.CSharp, Version=4.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'Microsoft.CodeAnalysis.CSharp' with identity 'Microsoft.CodeAnalysis.CSharp, Version=4.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
I've created a minimal reproduction repo here: https://github.com/adamfk/dotnet-script-issue1
It has a proj directory for a regular C# project (that works), and a script directory for the dotnet-script equivalent which fails.
The script file test.csx is tiny:
#!/usr/bin/env dotnet-script
#r "nuget: StateSmith, 0.8.2-alpha"
using StateSmith.Output.Gil;
WriteLine("Started running...");
GilHelper.Compile("public class Blah{}", out var a, out var b);
WriteLine("Finished running.");When I run it with --debug --no-cache, here's the output I get:

I'm hopeful that I can simply downgrade the StateSmith Roslyn dependencies to 4.4.0. Any other ideas?
Sidebar: StateSmith generates state machine code written in C#, then I use Roslyn to transpile that C# to C99, and also a more efficient C# implementation. I'll be transpiling to javascript/typescript in a few weeks. I'm hoping to have StateSmith create state machines for most programming languages :)
Thanks for the awesome project!
