我在将Application Insights连接到ASP WEB API Core时遇到了麻烦。按照标准手册，我仍无法在AppInsights帐户中找到任何记录。我使用了很多手册，但它们完全相同，并描述了如何为ASP Core（而不是API Core）配置App Insights。所以我想知道是否需要一些特殊配置（或nuget包或其他）来使AppInsights跟踪我的API服务请求？

一旦我无法使AppInsights无法正常工作，我仍然可以创建TelemetryClient实例并手动发布数据，但在我的情况下这是不可取的。

重要提示：我正在使用VS 2017 RC，Web APi Core项目（csproj）

Startup.cs中的配置：

    public class Startup
    {
        public Startup(IHostingEnvironment env)
        {
            var builder = new ConfigurationBuilder()
                .SetBasePath(env.ContentRootPath)
                .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);

            if (env.IsDevelopment())
            {
                // This will push telemetry data through Application Insights pipeline faster, allowing you to view results immediately.
                builder.AddApplicationInsightsSettings(true);
            }

            builder.AddEnvironmentVariables();

            Configuration = builder.Build();
        }

        public IConfigurationRoot Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();

            services.AddApplicationInsightsTelemetry(Configuration);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug(LogLevel.Trace);
            loggerFactory.AddConsole(LogLevel.Error);

            app.UseApplicationInsightsExceptionTelemetry();

            app.UseMvc();
        }

Answer 1

如果你在VS2017中使用“新的”asp.net核心，那么旧指令是错误的，因为它们适用于之前基于xproj的asp.net核心实现。

如果您在VS2017中创建新 asp.net核心Web项目，ApplicationInsights将从一开始就安装，应该是版本：

<PackageReference Include="Microsoft.ApplicationInsights" Version="2.2.0" />
<PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.0.0" />

（或更新，如果asp.net核心团队完全更新了它们）

这些项目已经将Application Insights连接起来，而不是Startup.cs（这是旧的方式），但是在Program.cs中：

new WebHostBuilder()
   ...
   .UseApplicationInsights() // this starts up appinsights in asp.net core now
   ...
   .UseOtherThings();

可能在网页模板中，例如：

 @inject Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet JavaScriptSnippet

位于顶部，

 @Html.Raw(JavaScriptSnippet.FullScript)

在<head>标记的底部。

如果您从以前版本的asp.net核心和应用洞察迁移，您还必须删除以下内容：

@Html.ApplicationInsightsJavaScript(TelemetryConfiguration)

从_Layout.cshtml

并用上面的行替换它们，你可以删除所有的行，如：

app.UseApplicationInsightsExceptionTelemetry（）;

在Startup.cs中（如果您使用的是2.x版本的软件包，我相信这些项目也会显示弃用警告，因为它们不再需要）

VS2017的官方发行说明将此信息作为"known issues" for application insights

中的一部分

Answer 2

由于article

，这个问题已经解决了

我的配置错过了2点：
1.在csproj中应该引用包＆＃34; Microsoft.ApplicationInsights.AspNetCore＆＃34;版本=＆＃34; 2.0.0-β1＆＃34;
2.在Startup类中，方法配置我错过了添加app.UseApplicationInsightsRequestTelemetry（）;

当我更改上述内容时，AppInsights已开始跟踪所有请求
