Windows IIS

Solution: Install the hosting bundle.

Reason: Although the SDK normally contains the runtime, however, it seems the SDK installer is not registering the runtime correctly on the server.

Workaround (not recommended):

Change AspNetCoreModuleV2 to AspNetCoreModule inside web.config.

Azure platform hosting

Install the .NET Core runtime extension by selecting Extensions and then installing .NET Core Runtime.
