.NET Core 3 support

[TFTomSun]

Can you please add .net core 3 support for the global tool? Background: I use scripting in a CI/CD pipeline. Since I upgraded to the .net core 3 docker image from microsoft, i can't install the dotnet script tool anymore. I think its just a small change in the TargetFrameworks msbuild property to support both, .net core 2.1 and .net core 3.

We are currently working with .Net Core 3 support.
It is however not as easy as adding another target framework.
The 3.0 SDK introduces some changes with regards to how we collect runtime assemblies for executing a script. This also affects compilation assemblies which we need in OmniSharp to provide intellisense and language services in OmniSharp (C# extension).

You can follow this branch for the progress on this.

Is there any way to run a preview version of the .Net Core 3 version?

Looking forward to this! I have built an EF 6.3 code generator for .NET Core using CSX files, but the assembly loading mechanism in 3.0 is causing some problems. You can see it demonstrated here: https://github.com/robertmclaws/EDMXParsingSample.

I'm actually glad it happened because it exposed a flaw in the EF6.3 metadata parsing code, but it's slowed my plans for releasing my framework. I'm generating the code with a dotnet tool in the meantime, but will be great when the scripts can work too.

Thanks for all your efforts on this project!

The branch you're mentioning in your link is gone. What is the progress so far?

[seesharper]

That is because we have merged it to master. We are working on the final bits now

We have just released version 0.50.0 adding support for .Net Core 3.0

@seesharper , are there any upgrade instructions?

From what I can tell, the two places that need updates are in the omnisharp.json and launch.json file

omnisharp.json

{
  "script": {
    "enableScriptNuGetReferences": true,
-   "defaultTargetFramework": "netcoreapp3.1"
+   "defaultTargetFramework": "netcoreapp3.1"
  }
}

launch.json

{
    "name": ".NET Script",
    "type": "coreclr",
    "request": "launch",
    "program": "dotnet",
    "args": [
        "exec",
-       "~/.dotnet/tools/.store/dotnet-script/0.52.0/dotnet-script/0.52.0/tools/netcoreapp2.1/any/dotnet-script.dll",
+       "~/.dotnet/tools/.store/dotnet-script/0.52.0/dotnet-script/0.52.0/tools/netcoreapp3.1/any/dotnet-script.dll",
        "${file}"
    ],
    "cwd": "${workspaceRoot}",
},

dotnet script init in the script folder should update those values.. If not try to delete the omnisharp.json file and the .vscode folder and then do a dotnet script init
