I installed VS 2017
along with .NET Core SDK
on Windows 10. But it did not install ASPNETCoreModule
as shown in figure 2 below. I thought
ASP.NET Core Module is installed separately from the SDK
It's not true since the release of 2.1. I'm experiencing the same issue on Windows Server 2016. The module was installed on developer PC after uninstalling old versions / installing 2.1 a few times, but still struggling with the same issue in 2016. %SystemRoot%\system32\inetsrv\aspnetcore.dll is still missing.
