升级到.NET Core 1.1.1后，ASP.NET Core MVC应用程序见解停止工作 [英] ASP.NET Core MVC application insights stopped working after upgrade to .NET Core 1.1.1

问题描述

2016年12月，我有一个简单的ASP.NET Core应用程序正在使用.它可以很好地与应用程序见解和遥测结合使用.

I have one simple ASP.NET Core application I was working on back in December 2016. It worked just fine with application insights and telemetry.

现在四个月后，我想开始这项工作，并开始从.NET Core 1.1.0升级到1.1.1.在此过程中，软件包Microsoft.ApplicationInsights.AspNetCore从版本1.0.2更新到了版本2.0.0.

Now after 4 months I wanted to pick up this work and started with upgrade from .NET Core 1.1.0 to 1.1.1. In this process package Microsoft.ApplicationInsights.AspNetCore got updated from version 1.0.2 to version 2.0.0.

不幸的是，这导致我的应用程序停止运行，尤其是出现此错误:

This unfortunately caused my app to stop working, in particular I get this error:

An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately.

/Views/Shared/_Layout.cshtml

'IHtmlHelper<dynamic>' does not contain a definition for 'ApplicationInsightsJavaScript' and no extension method 'ApplicationInsightsJavaScript' accepting a first argument of type 'IHtmlHelper<dynamic>' could be found (are you missing a using directive or an assembly reference?)
+
    @Html.ApplicationInsightsJavaScript(TelemetryConfiguration)

namespace AspNetCore
{
#line 1 "/Views/_ViewImports.cshtml"

屏幕:

从project.json升级到新的csproj并使用新的Visual Studio 2017没有帮助.

Upgrade from project.json to new csproj and using new Visual Studio 2017 doesn't help.

看来ApplicationInsightsJavaScript已从API中基本删除.那我该如何启用javascript应用程序见解?

It looks like ApplicationInsightsJavaScript was basically removed from API. How do I enable javascript application insights then?

推荐答案

从ApplicationInsights 1.x到2.x的重大更改已在GitHub

There are breaking changes from ApplicationInsights 1.x to 2.x which are documented on GitHub release notes.

• 此版本包含对SDK内部的重写，以实现更好的.NET 核心集成和初始化.
• UseApplicationInsightsRequestTelemetry已过时，它使用的逻辑 现在将自动处理要执行的操作，并调用此方法 应该从Startup.cs中删除.
• UseApplicationInsightsExceptionTelemetry已过时，异常 遥测现在在内部自动处理.你应该删除 从Startup.cs对此方法的调用，否则您将得到重复 报告了异常遥测.
• JavaScript的MVC依赖项 代码段已被删除，以便包含JavaScript代码段 现在您需要进行以下更改:
  • 在_ViewImports.cshtml中，将@inject Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration TelemetryConfiguration替换为@inject Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet JavaScriptSnippet
  • 在_Layout.cshtml中替换 @Html.ApplicationInsightsJavaScript(TelemetryConfiguration)和@Html.Raw(JavaScriptSnippet.FullScript)

• This release contains a rewrite of the SDK internals for better .NET Core integration and initialization.
• UseApplicationInsightsRequestTelemetry is obsolete, the logic it used to perform is handled automatically now and calls to this method should be deleted from Startup.cs.
• UseApplicationInsightsExceptionTelemetry is obsolete, exception telemetry is handled automatically internally now. You should delete calls to this method from Startup.cs otherwise you will get duplicate exception telemetry reported.
• The MVC dependency for the JavaScript snippet has been removed so in order to include the JavaScript snippet now you need to make the following changes:
  • In _ViewImports.cshtml replace @inject Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration TelemetryConfiguration with @inject Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet JavaScriptSnippet
  • In _Layout.cshtml replace @Html.ApplicationInsightsJavaScript(TelemetryConfiguration) with @Html.Raw(JavaScriptSnippet.FullScript)
