CRM Connection Error: Value cannot be null. Parameter name: authenticationCredentials.SupportingCredentials

I just published a blog post on my company's blog site, which explains the reason why you might encounter the "Value cannot be null. Parameter name: authenticationCredentials.SupportingCredentials" error when connecting to CRM discovery service.

This error could happen when you use CRM SDK code, Plugin Registration Tool, or CRM Developer Toolkit to discover CRM organizations.

Since the blog post particularly discusses the usage SSIS Integration Toolkit and relevant screenshots, so I will keep the post there, but provide a link here.

Hope this helps.

CRM Developer Chat with Fellow MVPs and Resource Links

Today, I had the privilege to do a Google Hangout with three fellow CRM MVPs (Donna Edwards, Dave Berry and Jamie Miley) to talk about some CRM development practices, including development tools, HTML5 vs Silverlight, CRM Polaris and Orion releases, JavaScript, JSON, etc.

I had a lot of fun during the session, particularly when Jamie decided to put a pirate hat on himself.

You can watch the recording of the session below.
