无法解析类型＆＃39; Microsoft.ApplicationInsights.TelemetryClient＆＃39;

Question

我已将我的Web项目从RC1迁移到RC2，但我遇到此错误：

  

无法解析类型的服务   ＆＃39; Microsoft.ApplicationInsights.TelemetryClient＆＃39;在尝试时   启用   ＆＃39; Microsoft.ApplicationInsights.AspNetCore.ExceptionTrackingMiddleware＆＃39;

有什么想法吗？

Answer 1

您需要将"Microsoft.ApplicationInsights.AspNetCore": "1.0.0-rc2-final"添加到project.json，然后添加到Startup班级：

public void ConfigureServices(IServiceCollection services)
{
    ...
    // Add framework services.
    services.AddApplicationInsightsTelemetry(Configuration);
    ...
}

public void Configure(IApplicationBuilder app)
{
        ...
        app.UseApplicationInsightsRequestTelemetry();
        app.UseApplicationInsightsExceptionTelemetry();

        ...
        app.UseMvc();
}
