RazorLight VS RazorEngine

Yes, I have used Razor pages in non-website applications before where I needed to load the cshtml templates from a different source. I have written Line of Business apps (think WinForms or WPF) where the reporting spits out HTML with tables and charts. There are a number of similar projects to yours out there which I have used in the past such as RazorLight or RazorMachine.

Your mileage may vary but I've had good luck with the RazorLight library for generating HTML emails from a template with data merged in. Under the hood, it uses the ASP.NET Razor engine for applying a model to a template.

We use https://github.com/toddams/RazorLight in combination with serverless functions.

you could use a razor based engine to generate html based on a view model (your data). take a look at: https://github.com/toddams/RazorLight i use it to generate html emails

Rails has a templating system for generating emails (standard HTML/ERB files). If you're running an ASP.NET Web API (not MVC) the best way of doing that I've found is via Razorlight which you have to set up manually - https://github.com/toddams/RazorLight

With Rails the standard is pretty much Devise or Omniauth (or both) - does everything for you. I've never found anything for ASP like Devise which gives you an entire login system with all the required views/migrations in a couple commands.

I use RazorLight: https://github.com/toddams/RazorLight

Razor Light

There's a load of packages to do it for example https://github.com/Antaris/RazorEngine

For HTML, you can use Razor from ASP.NET, either by making a web application you call with the data to get backthe page (microservice approach) or by shoving the Razor engine into your current application and rendering to strings.

Sorry! I only realised the need on Monday when my .NET Standard Library that contains .cshtml templates broke when I added .razor support. I use RazorLight and used to use RazorEngine before that.
