You will need to have IIS set up in order to get it to work correctly.
You also need to ensure you are using the .NET Core Windows Server Hosting Bundle
Then:
Restart the system or execute net stop was /y, followed by net start w3svc from a command shell. Restarting IIS picks up a change to the system PATH, which is an environment variable, made by the installer.
After that open the command prompt as Administrator and type:
C:\Windows\System32> iisreset
Then publish the app to a folder and open the command prompt there. Run the application by typing
C:\Temp\publish> dotnet YourApplicationName.dll
You can now go to the browser and type in http://localhost:port/ and it will display your .Net Core app.

Using sql server auth worked for me.
I use connection string like this:
Server=.;
Database=myDB;
User Id=sa2;
Password=myPass;
