Using Razor outside of MVC in .NET Core
You can use Razor outside of MVC in .NET Core by creating a new Razor Page or Razor View and rendering it manually in your application code. Here's an example of how you can do this: Create a new Razor Page or Razor View in your project. You can do this by adding a new file with the .cshtml extension to a folder in your project, such as the Views folder. Write the Razor code for your page or view. You can use the same Razor syntax that you would use in an MVC application, including C# code blocks, HTML helpers, and layout pages. In your application code, create a new instance of the RazorViewEngine class and use it to find and compile your Razor Page or Razor View. csharpusing Microsoft.AspNetCore.Mvc.Rendering; using Microsoft.AspNetCore.Mvc.ViewEngines; using Microsoft.AspNetCore.Mvc.ViewFeatures; using Microsoft.Extensions.DependencyInjection; // Create a new service provider var serviceProvider = new ServiceCollection() .AddSingleton() .BuildServiceProvider(); // Create a new ViewEngineResult for the Razor Page or Razor View var viewEngine = serviceProvider.GetRequiredService(); var viewName = "MyPage"; // Replace with the name of your Razor Page or Razor View var viewResult = viewEngine.GetView(null, viewName, false); // If the view was not found, return a 404 error if (!viewResult.Success) { return NotFound(); } // Create a new ViewDataDictionary with any necessary model data var viewData = new ViewDataDictionary(new EmptyModelMetadataProvider(), new ModelStateDictionary()) { Model = model // Replace with your model data, if any }; // Create a new TempDataDictionary var tempData = new TempDataDictionary(); // Create a new ViewContext with the required information var viewContext = new ViewContext( new ActionContext(HttpContext, RouteData, new Microsoft.AspNetCore.Mvc.Abstractions.ActionDescriptor()), viewResult.View, viewData, tempData, TextWriter.Null, new HtmlHelperOptions()); // Render the Razor Page or Razor View to a string using (var writer = new StringWriter()) { await viewResult.View.RenderAsync(viewContext); return writer.ToString(); }In this example, we create a new instance of the RazorViewEngine class and use it to find and compile a Razor Page or Razor View called "MyPage". We then create a new ViewDataDictionary and TempDataDictionary with any necessary model data, and create a new ViewContext with the required information. Finally, we render the Razor Page or Razor View to a string using a StringWriter, and return the resulting string. Note that you can replace TextWrite.Null with any TextWriter instance that you want to use to capture the rendered output. This approach allows you to use Razor for generating HTML or other types of text output in your .NET Core application, without having to use the full MVC framework.
