咨询ASP.NET Core下Application Insights实时指标流对应的.NET Core包

Absolutely, there's a dedicated solution for enabling Live Metric Stream in .NET Core applications—you don't need to rely on the .NET Framework-only Microsoft.ApplicationInsights.Web package.

Here's what you need to know:

• The official, .NET Core-compatible package is Microsoft.ApplicationInsights.AspNetCore. This is the core SDK for integrating Application Insights into ASP.NET Core apps, and it includes built-in support for Live Metric Stream out of the box.
• For non-ASP.NET Core .NET Core apps (like console services or background workers), you can use the base Microsoft.ApplicationInsights package, then configure telemetry settings to enable Live Metrics (setup is a bit more manual compared to web apps, but fully supported).

Quick Setup for ASP.NET Core Apps: #

1. Install the package via NuGet:

   Install-Package Microsoft.ApplicationInsights.AspNetCore
   # Or use .NET CLI
   dotnet add package Microsoft.ApplicationInsights.AspNetCore
   

2. Configure Application Insights in your code:
   • For .NET 6+ (top-level statements in Program.cs):

     var builder = WebApplication.CreateBuilder(args);
     // Add Application Insights telemetry
     builder.Services.AddApplicationInsightsTelemetry();
     // Rest of your app configuration...
     

   • For older .NET Core versions (using Startup.cs):

     public void ConfigureServices(IServiceCollection services)
     {
         services.AddApplicationInsightsTelemetry(Configuration["ApplicationInsights:InstrumentationKey"]);
         // Other service setups...
     }
     

3. Once configured, Live Metric Stream will be enabled by default. You can access it directly from your Application Insights resource in the Azure portal—no extra packages or complex tweaks required.

A key point to note: Live Metric Stream in .NET Core supports all the core features you'd get with the .NET Framework version, including real-time request rates, exception tracking, and custom metric streaming.
