Published app in single file mode and in trimmed mode with embedded kernel crashes on creating kernel

[WhiteBlackGoose]

Describe the bug

I use Microsoft.DotNet.Interactive.CSharp in the app and dotnet publish it. For repro I made a dummy app which just runs the user's code.

Command:

dotnet publish -c release -r win-x64 -o testpub --self-contained

Program.cs

```cs using Microsoft.DotNet.Interactive.CSharp; using Microsoft.DotNet.Interactive; using Microsoft.DotNet.Interactive.Commands; using Microsoft.DotNet.Interactive.Events; using Microsoft.DotNet.Interactive.Formatting; Formatter.SetPreferredMimeTypeFor(typeof(object), "text/plain"); var kernel = new CSharpKernel(); var currInput = 0; while (true) { var currInputLocal = currInput; var code = ReadBlock("Your input", currInputLocal); var computed = await kernel.SendAsync(new SubmitCode(code)); computed.KernelEvents.Subscribe(e => { switch (e) { case (CommandSucceeded s): WriteBlock("Outcome", currInputLocal, "Success"); break; case (DisplayEvent display): WriteBlock("Result", currInputLocal, display.FormattedValues.First().Value); break; case (CommandFailed failed): WriteBlock("Error", currInputLocal, failed.Message); break; } }); currInput++; } static void WriteBlock(string prefix, int id, string text) { Console.WriteLine(); Console.Write($"{prefix} [{id}]: "); Console.Write(text); Console.WriteLine(); } static string ReadBlock(string prefix, int id) { Console.WriteLine(); Console.Write($"{prefix} [{id}]: "); var text = Console.ReadLine(); Console.WriteLine(); return text; } ```

hw.csproj

```xml Exe net6.0 enable enable true ```

Single file

When publishing in single file, I get

Unhandled exception. System.ArgumentNullException: Value cannot be null. (Parameter 'path')
   at System.IO.Directory.InternalEnumeratePaths(String , String , SearchTarget , EnumerationOptions )
   at Microsoft.DotNet.Interactive.CSharp.InteractiveWorkspace.ResolveRefAssemblies()

   at Microsoft.DotNet.Interactive.CSharp.CSharpKernel..ctor()
   at Program.<Main>$(String[] args) in D:\tmp\test\hw\Program.cs:line 9
   at Program.<Main>(String[] args)

(see Bug 1 in the csproj file from above)

Trimmed mode

And that's what I get for trimmed mode (link)

error CS0656: Отсутствует обязательный для компилятора член "System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AwaitOnCompleted"

(fuck exception localisation. It says "missing required member for the compiler")

(see bug 2 in the csproj file)

• OS
  • [x] Windows 10

[shadowmint]

This issue persists in the latest (1.0.0-beta.22175.2) version as well, although the error has moved slightly, it remains in ResolveRefAssemblies.

System.NullReferenceException: Object reference not set to an instance of an object.
   at Microsoft.DotNet.Interactive.CSharp.InteractiveWorkspace.TryParseVersion(String versionString, Version& v)
   at Microsoft.DotNet.Interactive.CSharp.InteractiveWorkspace.ResolveRefAssemblyPath()

   at Microsoft.DotNet.Interactive.CSharp.CSharpKernel..ctor(String name)
   at Microsoft.DotNet.Interactive.CSharp.CSharpKernel..ctor()

ie. Currently its not possible to use this package when in 'self-contained' mode.

[jonsequitur]

We don't currently plan to make these libraries trimmable and many of their dependencies are not yet trimmable.

If the API allowed the user to supply the MetaDataReference's, like the CSharpCompilation.CreateScriptCompilation API, it could probably work in single file mode. Although it is still not pretty.
