Cannot get SQL Server 2019 MDS Model values to display in the Model drop list on MDS Website Title Page. Was able to get Models to display in SQL Server 2017 MDS OK. Managed to configure both MDS 2019 Website and MDS 2019 Web Service and Excel MDS 2019 Add-in successfully connecting to SQL Server 2019 MDS, but very frustrated with models not displayed in Model drop list on Title Page of MDS 2019 Website and in MDS 2019 Website System Administration Section, However, Models are available in User and Group Permission Section of MDS 2019 Website. Had to do a good deal of configuration of MDS 2019 web.config and IIS Site applicationhost.config authentication and MDS 2019 configuration sections to get MDS 2019 Website and MDS 2019 Service working OK. If you can help then I will greatly appreciate it. Cheers Pete.
