ASP.NET Core Razor Pages and Markup

Razor is a concise markup language that integrates server-side code (C# or VB) into ASP.NET web pages seamlessly. It simplifies web development by blending code and HTML, enhancing productivity and maintainability.

@page
@model IndexModel
@{
    ViewData["Title"] = "Home page";
}
<h1>@ViewData["Title"]</h1>
<p>Welcome to my ASP.NET Core Razor Pages!</p>

In this code snippet, the @page directive specifies the page, @model defines the page's model, and @ViewData displays dynamic data within the Razor Page markup.

Config Injection & Options Pattern in Razor Page

Inject Configuration

To inject configuration settings in your ASP.NET Core application, use Microsoft.Extensions.Configuration and inject IConfiguration into your page or component. Access configuration values using Configuration["KeyName"].

@using Microsoft.Extensions.Configuration
@inject IConfiguration Configuration

<!-- Access configuration value -->
@Configuration["ApplicationInsights:InstrumentationKey"]

Options Pattern

For more structured configuration management, use the options pattern with Microsoft.Extensions.Options. Inject IOptionsMonitor<TOptions> with @inject and access configuration values through OptionsAccessor.Value.PropertyName.

@using Microsoft.Extensions.Options
@inject IOptionsMonitor<ApplicationInsightsOptions> ApplicationInsightsOptionsAccessor

<!-- Access configuration value -->
var instrumentationKey = ApplicationInsightsOptionsAccessor.Value.InstrumentationKey;

For detailed information, refer to the ASP.NET Core documentation on configuration options.
