Run into errors while opening the solution: Error: Cannot find an instance of the Microsoft.VisualStudio.Server.Services.MonoDevelop.SolutionUtilities+SolutionData service.

Describe the Issue

I have a asp.net core project. When I try to open it in VS code the C# Dev Kit extension gives me the following error message:

Run into errors while opening the solution: Error: Cannot find an instance of the Microsoft.VisualStudio.Server.Services.MonoDevelop.SolutionUtilities+SolutionData service.

Steps To Reproduce

I am not sure how to reproduce this, because it looks more of a bug.

Expected Behavior

The C# Dev Kit extension should load properly.

Start by opening the ASP.NET Core project in VS Code with C# Dev Kit 1.70.3 on the reported Windows and VS Code versions, then investigate the SolutionData service error shown during solution loading. Done means the C# Dev Kit extension loads the solution without this error; the issue provides no reliable reproduction steps or named files and tests.
