Hi, I'm using ASPNET CORE & Angular (single solution) v5.5.2.

I followed the instruction from Getting Started (for MacOSX) to run the project.

But I'm getting this exception when I was trying to run the project in Visual Studio for Mac:

I've found out the root caused, which is when trying to get the configuration from appsettings.json:

Thanks. /Tommy

    Hi ryancyq.

    It's my bad that running v5.5.2 but following v6.2.0 tutorial. It's working fine after I downloaded the latest version, which is v6.2.0.

    Thanks. /Tommy
