Possible to run .NET Core 3.1-preview1 in LINQPad?

Recently .NET Core 3.1-preview1 has released:
https://dotnet.microsoft.com/download/dotnet-core/3.1

I tried to switch file "C:\Program Files\LINQPad6\LINQPad.GUI.runtimeconfig.json" into this, but seems not working😂:

{
  "runtimeOptions": {
    "tfm": "netcoreapp3.1",
    "framework": {
      "name": "Microsoft.WindowsDesktop.App",
      "version": "3.1.0-preview1.19506.1"
    }
  }
}

Testing code:

typeof(int).Assembly.Location

Output:

C:\Program Files\dotnet\shared\Microsoft.NETCore.App\3.0.0\System.Private.CoreLib.dll

I expect the output should be: "C:\Program Files\dotnet\shared\Microsoft.NETCore.App\3.1.0-preview1.19506.1\...".

And I tried to modify the "C:\Users\MyUserName\AppData\Local\LINQPad\6.3.1\ProcessServer\3.0.0-x64\LINQPad6.Query.runtimeconfig.json", but seems it is a auto-generated file😂

Is it possible to using .NET Core 3.1 within latest LINQPad 6?

I've been working on it. There will soon be a checkbox in Edit | Preferences > Query to enable the 3.1 beta.

Note that the LINQPad host itself will still preference the 3.0 RTM; only your queries will run under 3.1

There's now a beta with this option. Let me know how you get along.
