How to apply this C# pattern in MVS?

Question

C++ / C#

Hello, tell me how and where to enter here? I googled that the first one is a template, but I did not find how to apply it. With NuGet packages, everything is more or less clear, but I didn’t figure out how to create a project.
First, you need to first create an ASP.NET Core web app:
dotnet new web -n fulfillment
And add Dialogflow NuGet package to the project. This package will allow us to parse requests from Dialogflow and generate responses:
dotnet add package Google.Cloud.Dialogflow.V2 --version 1.0.0-beta02

Answer 1

Win + run
cmd.exe
dotnet new web -n fulfillment
cd fulfillment
dotnet add package Google.Cloud.Dialogflow.V2 --version 1.0.0-beta02
run fulfillment.csproj
What is it all about?
