RenderViewToString HostBuilder setup

[genifycom]

I am trying to get the renderviewtostring sample working in DotNet Core 3.1 in a console application i.e. running Razor standalone.

The first statement in Main gives 'HostBuilder' does not contain a definition for 'ConfigureWebHost' ...

What is the correct setup for this sample in DotNet Core 3.1 ?

Thanks
