can't debuging and execute demo app

[박상훈]

Hi. I have some question.

An exception occurred while debugging the ExecutiveDashboard demo source code.

exception text : 
System.InvalidOperationException: 'An error occurred while processing this request.'
DataServiceTransportException: The request was aborted: Could not create SSL/TLS secure channel.
WebException: The request was aborted: Could not create SSL/TLS secure channel.



An error occurred while downloading and installing the ExecutiveDashboard demo app(setup.exe).

The same problem occurred with the SalesDashboard demo source code and app.

What caused the problem?

Hello,

We had an issue on the server where the services of the sample applications are deployed. We fixed that yesterday, so the demos should work now. Can you try them again and let me know if they are okay?
