hi :wave: @robyle

I think you'll get a quicker response on the Q & A site section for .NET. Right now, it's unclear where to update any of the relevant docs to address this. Please let us know if you've found an answer, or can point to the docs that led you astray.

Hi，I just follow the offical website: https://learn.microsoft.com/zh-cn/dotnet/spark/how-to-guides/connect-to-mongo-db

I run it，it will get the problem like my uploaded picture.
