Unable to use C# 9 in a script project

[germanftorres]

Hi!,

I'm trying to use the 'records' feature and others latest additions of C# 9 in a script project, but OmniSharp seems to be configured with LanguageVersion.CSharp8 hardcoded in ScriptProjectProvider and complaints about the feature not being available in C# 8.

omnisharp-roslyn/src/OmniSharp.Script/ScriptProjectProvider.cs

Line 46 in 93d2807

private static readonly CSharpParseOptions ParseOptions = new CSharpParseOptions(LanguageVersion.CSharp8, DocumentationMode.Parse, SourceCodeKind.Script);

Not sure if this value can be updated to CSharp9 or Latest without breaking existing projects. Any chance this may be configured throught omnisharp.json in it's script section?

Thanks!!

Germán
