Hi. Hoping someone can help me with this. Recently I set up an MDS website and database using SQL Server 2016 Master Data Services Configuration Manager. Everything worked, happy days!
Everything continued working until Monday morning when, after invoking the web app, I got the following error:-
Stack Trace:[InvalidCastException: Specified cast is not valid.]
Microsoft.MasterDataServices.WebUI.MDSApplication.Application_Start(Object sender, EventArgs e) +519
[HttpException (0x80004005): Specified cast is not valid.]
System.Web.HttpApplicationFactory.EnsureAppStartCalledForIntegratedMode(HttpContext context, HttpApplication app) +522

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET
Version:4.7.3429.0
In between it working and not working I have changed absolutely nothing at all on the server. I suspect that our remote IT Support dept may have changed something, and I am going to chase this up with them, but in the meantime was wondering if anyone else
had encountered this error or knew what it means?
Many Thanks.
Brian.
