I receive the "Invalid URI: The format of the URI could not be determined." when running a VB.Net app that connects to Microsoft CRM v 1.2. This app was originally written to connect to Microsoft CRM v 1.0. I need to update the app co connect to 1.2. The original app was written VB.Net 2002, using the DotNet Framework 1.0. 1.2 requires the 1.1 Framework, so I opened the app in VB.Net 2003 and used the 1.2 dlls instead of the 1.0 dlls (Microsoft.Crm.Platform.Proxy and Microsoft.Platform.Types respectively). The app builds ok, but when I run the portion of the app that generates an XML query, I get the above error. The original app connectiong to CRM 1.0 works fine.
