Not Able to run C# code #1942

I'm trying to run code-sever on google cloud shell and working on C#. I'm not able to run any C# program.
The DEBUG CONSOLE says

Here is the output of dotnet --info

Following are some of the specs of my working environment:

• Web Browser: Chrome
• Local OS: Windows 64-bit
• Remote OS: debian version 10
• Remote Architecture: x86_64
• code-server --version 3.4.1 48f7c2724827e526eeaa6c2c151c520f48a61259:

I had checked Differences compared to VS Code. But the extensions are working well. So I do not understand what can be done.

When I googled a bit on this I read dotnet/vscode-csharp#3775 (comment) and checked https://github.com/OmniSharp/omnisharp-vscode/wiki/Microsoft-.NET-Core-Debugger-licensing-and-Microsoft-Visual-Studio-Code. It says that we have to uninstall the existing VS Code and install the fresh new VS Code from Microsoft. But that will not let me use code-sever or rather I do not know as to how I can combine Microsoft's VS Code with code-server. Is it that I have to install a different extension for working with C# in code-server? Can someone please help how to sort out this issue?
