Creating custom dotnet new templates is nothing new, but you might not realise just how easy and how powerful they can be. You might think they are only for new .NET projects, but they're not! The dotnet new engine works with all text-based files, including XML, Markdown and YAML. You can publish them to Nuget as Lotte has done for the popular open-source .NET CMS Umbraco, share them within your organisation, or use them personally to speed up your development. In this session we shall walk through creating and testing a new 'project' template from a working application, and explore how 'item' templates can add features to existing projects. If you hate doing the same thing twice, want to accelerate the start of new projects, or aim to ensure consistency across all your projects, this session is for you. You’ll leave with the knowledge to create your own templates and plenty of ideas on how to use them. It’s time to retire those old PowerShell scripts!
