C# Intellisense doesn't suggest anything unless namespace explicitly used

Problem is Intellisense doesn’t suggest anything unless it is included in the script with using keyword.

using RAPID.SerializationContracts;
namespace RAPID
{
    class Program
    {
        static void Main(string[] args)
        {
            XMLFactory // <-- Intellisense suggests XMLFactoryContract
        }
    }
}

namespace RAPID
{
    class Program
    {
        static void Main(string[] args)
        {
            XMLFactory // <-- Intellisense has no suggestions despite the fact the files in the same project, just different namespaces.
        }
    }
}

Steps to reproduce

Unsure how. It just happened one day 🤔 🤔 Closest event was installation .NET Core 3.1 However, opening a project in Visual Studio doesn’t fix the issue. So might be something wrong on my end 🤔

this has already shipped in OmniSharp - we forgot to close the issue here.

You can read more here https://www.strathweb.com/2020/09/support-for-unimported-types-in-omnisharp-and-c-extension-for-vs-code/

TL;DR - you need to set "omnisharp.enableImportCompletion": true as the feature is not switched on by default.
