Assistance with using the latest Milestone SDK

I want to use a windows credential (NTLM Authentication) with the Milestone API. Appears I need to use the .NET SDK to create the token. Is there any way to create a token with windows credentials without using the .NET SDK?

Confusingly there are two tokens in play, an Oauth token from the IDP and a legacy token from the Management Server.

Using the Rest API you generally use the first.

The description about the bearer token for a basic authentication user is here under Get started - https://doc.developer.milestonesys.com/mipvmsapi/api/config-rest/v1/#section/Introduction/Get-started

For NTLM this might be a hint
