A compile error form example AzureIoT about azure-sphere-samples

Hi - you need to configure the app to work with your IoT Central or to work with your IoT Hub.

If you switch to the "Output -> Build" panel in Visual Studio, you will see this advice:

1>------ Build started: Project: AzureIoT, Configuration: Debug ARM ------
1>Validating project app_manifest.json
1>CmdArgs is empty, this needs to contain the ScopeId for your IoT Hub/Central application
1>The app_manifest.json 'AllowedConnections' needs to contain:
1>  Your IoT Hub/Central application Endpoint address
1>The app_manifest.json file contains a placeholder 'DeviceAuthentication'
1>this needs to be replaced with your Azure Sphere Tenant Id
1>This can be obtained using the Azure Sphere Developer Command Prompt
1>'azsphere tenant show-selected'
...
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Please let us know if this solves the problem, thanks.

Thank you. The content in app_manifest.json can not be left blank when build the code. Now the demo code can runs with IoT central.
