Data8.PowerPlatform.Dataverse.Client 2.2.0

Data8 .NET Core Client SDK for On-Premise Dynamics 365/CRM

The Microsoft.PowerPlatform.Dataverse.Client package provides an SDK for connecting to Dataverse & Dynamics 365 instances from .NET Core, but relies on OAuth authentication. This poses a problem when you need to connect to an on-premise instance that either does not support OAuth, or where the OAuth tokens regularly expire and cannot be automatically refreshed.

This package Data8.PowerPlatform.Dataverse.Client builds on top of the Microsoft one and offers an alternative IOrganizationService implementation using WS-Trust. This allows you to connect using the URL of the organization service, username and password without any additional configuration.

Because this OnPremiseClient implements the same IOrganizationService as the standard ServiceClient implementation your code can work with either as shown in the sample code below.

Sample

using Data8.PowerPlatform.Dataverse.Client;
using Microsoft.PowerPlatform.Dataverse.Client;
using Microsoft.Xrm.Sdk;

var onPremIfd = new OnPremiseClient("https://org.crm.contoso.com/XRMServices/2011/Organization.svc", "AD\\username", "password!");
var onPremAD = new OnPremiseClient("https://crm.contoso.com/org/XRMServices/2011/Organization.svc", "AD\\username", "password!");
var online = new ServiceClient("AuthType=ClientSecret;Url=https://contoso.crm.dynamics.com;ClientId=637C79F7-AE71-4E9A-BD5B-1EC5EC9F397A;ClientSecret=p1UiydoIWwUH5AdMbiVBOrEYn8t4RXud");

CreateRecord(onPremIfd);
CreateRecord(onPremAD);
CreateRecord(online);

void CreateRecord(IOrganizationService svc)
{
	var entity = new Entity("account")
	{
		["name"] = "Data8"
	};

	entity.Id = svc.Create(entity);
}

Compatibility

This package is designed to be used with on-premise Dynamics 365 instances. Supported authentication types are:

  • Integrated Windows Authentication
  • Claims-Based Authentication
  • Internet Facing Deployment

The package targets .NET Core 3.1 or later. It can also be used on .NET Framework 4.6.2 or later.

Notes on Integrated Windows Authentication

If claims-based authentication is not configured on your Dynamics 365 instance, you will be using Integrated Windows Authentication. This library can authenticate to these instances, but only where the client is either:

  • running on Windows, or
  • running on Linux under .NET 7 and with the gss-ntlmssp package installed

You can choose to supply a username (in the format DOMAIN\Username or username@domain) and password, or leave both blank to authenticate as the currently logged on user.

Thanks

Many thanks to Data8 for the time to develop this library and release it for public use.

This project builds on the work of the NSspi library to handle the internals of working with the Windows authentication functions pre-.NET 7. Unfortunately the latest release of NSspi was missing a few required methods, so it is currently including some code from a fork of that library.
