BC Integration with Dataverse - altpgen failing

(0) ShareShare
ReportReport
Posted on by 335

Hi, 

I am trying to set up the integration between BC and Dataverse - I ran the initial setup from the Assisted Setup and looks good. I would like to extend and customize the integration using the AL Table Proxy Generator (altpgen) as explained in this MS Documentation; 

https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-al-table-proxy-generator

however as soon as I run the altpgen command, it asks me to authenticate which I do but then fails as per below error in powershell; 

Authenticating Dataverse using ServiceUri=https://orgxxxxxxxx.crm.dynamics.com/
error CDS0001: Error connecting to Dataverse.
Microsoft.Dynamics.Nav.Xrm.Common.XrmException: Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=5.2.7.0, Cultu
re=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

This is using BC SaaS and the AL Extension in VS Code is updated to the latest too. 

Any idea what could be the issue here, please? 

Thanks in advance!
