The library has a static engine accessible through Engine.Razor, but we can also create an instance of the Razor engine for use in our applications. Keep your templates as simple as possible, if you need to inject “unusual” assemblies most likely you are doing it wrong. Writing @using System.IO in template will not reference System.IO assembly, use builder to manually reference it. For reasons I don’t understand without looking at the source CreateEmbedded requires a class in the same location as the views or it will error when looking for the views. However, this is used in several different projects, and by default RazorViewEngine seems to only look in the Views folder for the Web project in question.

  • The Razor engine does not have many of the features found in ASP.NET MVC.
  • Building on @turdus-merula’s answer, I wanted the temp files to be cleaned up when the default AppDomain is unloaded.
  • You then implement the two methods of the IViewEngine interface, namely GetView and FindView.
  • The two are separate technologies, although ASP.NET MVC does utilize Razor as its HTML rendering engine.
  • Starting with ASP.NET Core 3.0, MVC Views or Razor Pages aren’t served by default if the RazorCompileOnBuild or RazorCompileOnPublish MSBuild properties in the project file are disabled.
  • When you create a custom view engine, you might often want to remove the default view engines.

In this method, we define a dynamic project that is to be compiled. I have included the class SampleEmailTemplateCollectionItem, which is there purely to demonstrate iteration in the view using a strongly-typed object. In this article, I’ll show you how to use Roslyn, the .NET compiler, to leverage the Razor Engine in other project types, and define your project in a way that better suits you. The API is designed around the idea that you do not have the templates sitting around in the source code
(while you can do that as seen above). The main interface to provide RazorEngine with templates is the ITemplateManager interface.

Build and test the project

There is no MVC in that piece of code, so, no View, no .cshtml files, no Controller, just Razor source parsing and compiled runtime execution. RazorLight is not currently designed to support such integration tests. Then, you can mock in your integration tests any dependencies asp net razor tutorial on RazorLight. If you store your templates in database – it is recommended to create custom RazorLightProject that is responsible for gettings templates source from it. RazorLight will use it to resolve Layouts, when you specify it inside the template.

razor engine .net core

This method is responsible for rendering the view engine at runtime. A view engine translates a server-side template into HTML markup and renders it in the web browser when triggered by a controller’s action method. ASP.NET MVC initially shipped with the ASPX View Engine, but the Razor View Engine was added in later versions. The Razor View Engine is now the default view engine for ASP.NET Core MVC applications.

EmbeddedResource source

This approach has the advantage that there is no need to mess with path strings, and it keeps everything nicely contained in the one project. Suggest you move this logic into the model being passed into the view, rather than altering the cshtml. Obvious SOLID principle benefits and far easier to test the models in isolation.
