Hi @david langford ,
Per my research, if you want to build SharePoint 2016 WebParts, you must create it in SharePoint 2016 environment. But SharePoint 2016 doesn't support win10. It only support following operating systems :
Windows Server 2012 R2 Standard or Datacenter
Windows Server 2016 Standard or Datacenter
Windows Server 2019 Standard or Datacenter
And I feel regretful to inform you that it turns out to be a by-design one. I also noticed that some end users have also proposed the same request, it is highly recommended that you can vote this ticket. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding.
