Razor View Engine & Razor Syntax in ASP NET Core

Another explanation can be found on this helpful StackOverflow article. In the above code, we’re telling the View which Model it should be using. The important thing to note here is that, contrary to what you may be more used to, we’re not telling the View to directly use the ViewModel. Instead, we’re adding a reference to a base-model (which we’ll talk about shortly).

That means we can’t merely transplant our MVC views into a console application and hope it all works. If you need the security behaviour of named pipes, then that’s a clear reason for choosing them. But we actually use named pipes in the Datadog .NET Azure App Service (AAS) Extension, and it has nothing to do with the security features. If that’s something you need, then it may be easier to use named pipes to razor engine .net core get these features, though I suspect there’s not a massive need for that these days. You can think of a duplex named pipe as being similar to a TCP/IP connection, in that you can send data to the server and can receive a response. Named pipes are a Windows kernel feature, so they’re not specific to .NET, although they have been accessible from .NET since .NET Framework 3.5 (to a greater or lesser extent).

Generate Outputs with Razor Engine in .NET Core

This approach can handle more complex rendering scenarios like partial views and injecting objects into views as well, although I’ll just demonstrate a simple example below. I would like to use Razor as a templating engine in a .NET console application that I’m writing in .NET Core. 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. You should either pick one of the available implementations or write your own. Both core team members and external contributors send pull requests which go through the same review process.

View engines play a crucial role in separating the presentation logic from the application’s business logic, promoting clean code architecture and maintainability. Razor Markup refers to the syntax used in Razor view templates in ASP.NET web applications to combine server-side code with HTML markup. Razor Markup allows developers to embed C# code directly within HTML, making generating dynamic and data-driven content for web pages easier. The Razor Markup syntax is designed to be concise, readable, and intuitive, enabling seamless integration of code and markup. The reason is the same as the issue with linked assets I mentioned before. You could setup a web server which would serve those files or probably even add Controller in your ASP.NET Core app, but this time converting the image to base64 string should work as well.

Hang on, why two helper classes?

In a more complicated system, you would persist the dynamic compilation, either by saving to disk semi-permanently or caching for longer periods. Dynamic compilation is a powerful tool to have at your disposal, but careless integration https://remotemode.net/ could cause you severe performance headaches. The act of bringing Roslyn into the runtime and the actual compilation step itself is computationally expensive, so you want to avoid repeating this work as much as possible.

  • The razorTemplateBaseFolder constant is used to define the name of the folder, in the host project, where we expect to find the .cshtml template file.
  • Impersonation in particular is a feature which sounds great on the surface, but which also kind of sounds like a privilege escalation issue waiting to happen.
  • At the end of this article, you will understand the following pointers.
  • In this Razor tutorial, we will take a quick tour of the Razor View Engine in ASP.NET Core MVC.
  • So the benefit you get from a static type will most likely not compensate the additional compile time.

Embedded logic, such as iteration and conditional branching, is a compelling feature to have at your disposal. Any HTML Elements inside the Razor code block is correctly identified by the Razor engine as shown below. The Variables are declared using the var keyword or using the c# data type. The int, float, decimal, bool, DateTime & string keywords can be used to store strings, numbers, and dates, etc.

Additionally Raw method is added, which mimics behavior of MVC’s HTML.Raw. You could omit and add properties for your model in RazorTemplate class. We use Activator.CreateInstance to create a new object, specifying that we now use the Assembly that we previously compiled to do this job. It is this mechanism that ultimately extends the base model with all of the RazorEngine functionality.
