Answer 2

You have to upgrade your nuget installer to latest version.

https://www.nuget.org/packages/Microsoft.EntityFrameworkCore.SqlServer.NetTopologySuite/

https://www.nuget.org/downloads

If you are using Azure Devops, you can add a task step into your pipeline.

- task: UseDotNet@2
      inputs:
        packageType: sdk
        version: 5.0.x

- task: NuGetToolInstaller@1
      inputs:
        versionSpec: ''
        checkLatest: true

Answer 3

I had a global.json file in my project. After removing it problem was fixed because it mentioned a .net core 3.1 sdk.

Open .csproj file in notepad and change the target version from 3.1 to 2.1 From
