🛠️ Creating the ShoppingBasket Solution

🧱 2. Create the Shopping Basket Web API Project

dotnet new webapi -n EvenTicket.Services.ShoppingBasket --use-controllers -o src/EvenTicket.Services.ShoppingBasket
dotnet sln add src/EvenTicket.Services.ShoppingBasket/EvenTicket.Services.ShoppingBasket.csproj
dotnet sln list

Here we have to pass unnecessary property which events service can be converted into graphql
