Referencing a package with X.Y.* version in .csproj results in Omnisharp not loading.

Issue Description

Referencing a package with a “starred” version (i.e. : 12.0.*) in the .csproj file results in Omnisharp failing to load.
A colleague of mine had the same issues on another project in another environment (Windows 10) and we fixed it in the same way by replacing the * by an actual version. All of this was done in .Net projects, I could not test it in another framework.

Steps to Reproduce

• dotnet new console test
• Open project.csproj file
• Add <ItemGroup> <PackageReference Include="Newtonsoft.Json" Version="12.0.*" /> </ItemGroup>
• Reload Omnisharp

Expected Behavior

Omnisharp normally loading and being functioning.

Actual Behavior

Omnisharp is not available anywhere in the project.

Thanks for reporting the problem. There is a new build since yesterday that should fix this. Could you try setting "omnisharp.path": "1.32.19-beta.25" in your VS Code settings and confirm? This will download the new OmniSharp from the master branch. Thanks.

@filipw thanks for your advice. Changing (for me, INCLUDING) “omnisharp.path”: “1.32.19-beta.25” on setting.json solved the problem!
