3. Add and use a NuGet package

NuGet packages included in your project are specified in your csproj file. Instead of manually editing the list of packages and versions, you can use the dotnet tool to make the changes for you.

<PackageReference Include="Swashbuckle.AspNetCore" Version="3.0.0" />

Open https://localhost:5001/swagger/ in a web browser to see documentation for your API.
