      Summary

      When using MongoDB Driver from NuGet, v 2.22.0

      When instantiating an **

      new MongoClient(connectionString)

       instance, with a connection string pointing to

      mongodb://localhost:27017

      The MongoClient object is called from a .Net 2.0 Standard library with 4.8 as Target, it runs as a Windows Service.
       
      I get the following error.
       

      "exception": "System.NullReferenceException: Object reference not set to an instance of an object.

      The same library has no issues connecting to the same Mongo instance when running inside of an Asp.Net 4.8 service.
